Conjunction of the Moon and Jupiter<\/strong> in Aries on October 1.<\/li>\n
Conjunction of the Moon and Venus<\/strong> in Leo on October 10.<\/li>\n
Conjunction of the Moon and Saturn<\/strong> in Aquarius on October 24.<\/li>\n
Conjunction of the Moon and Jupiter<\/strong> in Aries on October 29.<\/li>\n<\/ol>\n
October 1: Conjunction of the Moon and Jupiter<\/h2>\n
The Moon and Jupiter will be at conjunction by sharing the same right ascension and passing within 3\u00b023\u2032 of each other.<\/p>\n
At nearly the same time the two bodies will also make a close approach (appulse) reaching 3\u00b008\u2032 from each other, but no longer sharing the same right ascension.<\/p>\n
Both celestial bodies will be visible in the constellation of Aries with apparent magnitudes of -12.6 for the Moon and -2.8 for Jupiter. The Moon will be 16 days old or waning gibbous.<\/p>\nAries Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg). License: CC BY 3.0.<\/figcaption><\/figure>\n
October 2: Asteroid 29 Amphitrite at opposition<\/h2>\n
Asteroid 29 Amphitrite will reach opposition, when it lies opposite to the Sun in the sky, reaching the highest point in the sky around midnight local time, regardless of where in the world you are located.<\/p>\n
This asteroid will come within 1.426 AU of us, reaching a peak brightness of magnitude 8.8. Unfortunately it\u2019s much too dim to be visible to the naked eye, so a telescope of moderate aperture will be needed. Point it at the constellation of Pisces. The bright Moon will interfere as it will be waning gibbous at 17 days old.<\/p>\nPisces Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg).

Amphitrite was discovered in 1854 by Albert Marth and named after a sea goddess, consort of Poseidon and symbolic representation of the sea in Greek mythology.<\/p>\n
It is an S-type asteroid, with a mean diameter of just over 200 km, which would make it the fifth largest asteroid in the belt.<\/p>\nA three-dimensional model of 29 Amphitrite that was computed using light curve inversion techniques by Josef \u010eurech and Vojt\u011bch Sidorin from the Astronomical Institute of the Charles University.

October 2: The Andromeda Galaxy at its highest point in the sky<\/h2>\n
The largest galaxy in the local group, Andromeda (Messier 31, M31, or NGC 224), will reach its highest point in the sky at around midnight local time.<\/p>\n
It will reach apparent magnitude 3.4, but unfortunately the Moon will be interfering with observation because it will be waning gibbous at 17 days old. It would be very difficult to spot with the naked eye, but quite easy with a pair of binoculars or a small telescope. Look in the constellation of Andromeda, after which the galaxy was named.<\/p>\n
The Andromeda Galaxy looks like such a small pinprick of light when observed from Earth, but in reality you\u2019re looking at one trillion stars there!<\/p>\nAndromeda Constellation Map.

October 6: October Camelopardalid meteor shower peak<\/h2>\n
The October Camelopardalids are a small variable meteor shower that will peak on October 6. It is one of the shortest meteor showers with only two days in total. It will start on October 5 and end on October 6.<\/p>\n
The meteors will appear to radiate from a point between the constellations of Camelopardalis and Draco at an average speed of 46 km\/s. The Moon will be a waning crescent at 21 days old.<\/p>\nCamelopardalis Constellation Map IAU. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg).

October 8: Draconid meteor shower peak<\/h2>\n
The Draconids will peak on October 8 with a variable rate of meteors. Some meteors will also be visible from October 6 to October 10 and they will appear to radiate from the constellation of Draco at an average speed of 20 km\/s. They originate from debris left by the comet 21P\/Giacobini\u2013Zinner. The Moon will be a waning crescent at\u00a024 days old.<\/p>\nDraco Constellation Map.

October 10: Conjunction of the Moon and Venus<\/h2>\n
The Moon and Venus will be in conjunction because they will have the same right ascension and will pass within 6\u00b029\u2032 of each other.<\/p>\n
Around the same time, the two bodies will make a close approach (appulse), reaching 5\u00b054\u2032 from each other but no longer sharing the same right ascension.<\/p>\n
Both celestial bodies will be visible in the constellation of Leo with apparent magnitudes of -10.6 for the Moon and -4.5 for Venus. The Moon will be a waning crescent at 25 days old.<\/p>\nLeo Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg). License: CC BY 3.0.<\/figcaption><\/figure>\n
October 10: Southern Taurid meteor shower peak<\/h2>\n
The Southern Taurids are a small meteor shower with an average of 5 meteors per hour during the peak if conditions are ideal. However small it is during the peak, this meteor shower is very long lasting: from September 10 all the way to November 20.<\/p>\n
Meteors will appear to radiate from the constellation of Taurus at an average speed of 27 km\/s. They originate from debris of the comet Encke. During the peak, the Moon will be a waning crescent at 25 days old.<\/p>\nTaurus Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg).

October 11: \u03b4-Aurigid meteor shower peak<\/h2>\n
The Delta Aurigids are another small meteor shower with a peak of only 2 meteors per hour on average, assuming ideal conditions. During the peak the Moon will be a waning crescent at\u00a026 days old.<\/p>\n
Some meteors may also be seen between October 10 and 18. They will appear to radiate from the constellation of Auriga at the fast speed of 64 km\/s on average.<\/p>\nAuriga Constellation Map.

October 14: Annular solar eclipse<\/h2>\n
An annular solar eclipse happens when the Moon is too far away from the Earth to completely cover the Sun. This creates a ring of light around the darkened Moon. The corona is not visible during an annular eclipse.<\/p>\n
The eclipse will begin in the Pacific Ocean off the coast of southern Canada and continue across the southwestern United States, Central America, Columbia, and Brazil. A partial eclipse will also be visible across much of North and South America.<\/p>\n
Be careful to not look directly at the Sun and especially not to point a telescope at it. This is very dangerous to your eyes.<\/p>\n
<\/p>\n
October 15: The Triangulum Galaxy at its highest point in the sky<\/h2>\n
The Triangulum Galaxy (Messier 33, M33, or NGC 598) will reach its highest point in the sky at around midnight local time. It can be found in the Triangulum constellation, not far from its neighbor the Andromeda Galaxy.<\/p>\nTriangulum Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg). License: CC BY 3.0.<\/figcaption><\/figure>\n
It will reach apparent magnitude 5.8 with almost no interference from the Moon, which will be only one day old or a very thin waxing crescent. Even so, it would be extremely difficult to spot with the naked eye, so a pair of binoculars or a small telescope would be recommended.<\/p>\n
The Triangulum Galaxy is the third-largest galaxy in the Local Group, after Andromeda and Milky Way. It is 3.2 million light-years away from us and contains an estimated 40 billion stars.<\/p>\nThe VLT Survey Telescope (VST) at ESO\u2019s Paranal Observatory in Chile has captured this beautifully detailed image of the Triangulum Galaxy.

October 18: \u03b5-Geminid meteor shower peak<\/h2>\n
The Epsilon Geminids are a small meteor shower with only 3 meteors on average during the peak if conditions are perfect. Although the peak is on October 18, some meteors could also be spotted between October 14 and 27.<\/p>\n
The meteors will appear to radiate from the constellation of Gemini at the fast average speed of 70 km\/s. They originate from debris of the comet C\/1964 N1 (Ikeya).<\/p>\nGemini Constellation Map.

October 18: Dwarf planet Eris at opposition<\/h2>\n
On the night of October 18, the dwarf planet 136199 Eris will reach a point opposite to the Sun in the sky, known as an opposition. This will happen around midnight local time, regardless of where in the world you are.<\/p>\n
With an apparent magnitude of 18.6, you will most definitely need a powerful telescope. If you have access to one, look in the constellation of Cetus. The Moon won\u2019t be interfering much because it will be a thin waxing crescent at 4 days old.<\/p>\nCetus Constellation Map.

At about the same time, Eris will also make its closest approach to the Earth (perigee) at a distance of 94.75 AU, making this the best time to observe the dwarf planet.<\/p>\n
Eris was discovered in 2005 by the team of Mike Brown, Chad Trujillo, and David Rabinowitz and named after the Greek goddess of strife and discord. It has an estimated mean diameter of 2326 and an equatorial surface gravity of 0.084. It is only slightly smaller in diameter, yet much more massive than Pluto.<\/p>\n
A large moon has also been discovered around the dwarf planet and named Dysnomia after the daughter of the Greek goddess Eris. It has a mean diameter of about 615 km.<\/p>\nArtist\u2019s impression of the dwarf planet Eris in the distance with its moon Dysnomia in the foreground. Credit: ESO\/L.

October 22: Orionid meteor shower peak<\/h2>\n
The Orionids are a medium sized meteor shower with an average of 15 meteors during the peak if conditions are optimal. Although the peak of this meteor shower is October 22, some meteors can also be seen between October 2 and November 7.<\/p>\n
The meteors will appear to radiate from the constellation of Orion at the fast speed of 66 km\/s on average. They originate from debris left behind by the famous Halley\u2019s Comet. The Moon will be waxing gibbous at\u00a08 days old.<\/p>\nOrion Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg).

October 22: Comet 2P\/Encke at perihelion<\/h2>\n
The comet Encke (official designation: 2P\/Encke) will make its closest approach to the Sun (known as perihelion) on October 22, at a distance of 0.34 AU. It will be located in the constellation of Virgo at an apparent magnitude of 6.2. As mentioned earlier, the Moon will be waxing gibbous at 8 days old.<\/p>\n
Comet Encke was discovered in 1786 by Pierre M\u00e9chain, who didn\u2019t know it was a periodic comet. This fact was only discovered in 1819 by Johann Franz Encke when he calculated the orbit of the comet.<\/p>\n
Encke is a periodic comet that completes an orbit of the Sun once every 3.3 years. Such a short orbital period means that this comet spends most of its time in the asteroid belt, never crossing Jupiter\u2019s orbit, and periodically dipping sunward into the inner solar system.<\/p>\nVirgo Constellation Map.

October 24: Conjunction of the Moon and Saturn<\/h2>\n
The Moon and Saturn will be at conjunction by reaching 2\u00b046\u2032 from each other while sharing the same right ascension. The pair will be too far apart to be visible together using a telescope, but they will be viewable with the naked eye or a pair of binoculars.<\/p>\n
Shortly after the conjunction, the Moon and Saturn will get even closer to each other at 2\u00b032\u2032 during the appulse, but no longer sharing the same right ascension.<\/p>\n
The two bodies can be seen in the constellation of Aquarius with an apparent magnitude of -12.4 for the Moon and 0.5 for Saturn. The Moon will be waxing gibbous at 10 days old.<\/p>\nAquarius Constellation Map. Credit: IAU and Sky & Telescope magazine (Roger Sinnott & Rick Fienberg).

October 24: Leonis Minorid meteor shower peak<\/h2>\n
The Leonis Minorids are the final meteor shower to peak this month of October. It is a small one with only 2 meteors per hour on average during the peak, with ideal viewing conditions. Unfortunately the viewing conditions will not be ideal because of the Moon\u2019s interference. It will be waxing gibbous at 11 days old.<\/p>\n
Some meteors can also be seen between October 19 and 27, radiating from the constellation of Leo Minor at the high average speed of 62 km\/s.

October 28: Partial lunar eclipse<\/h2>\n
A partial lunar eclipse happens when the Moon passes through the Earth\u2019s partial shadow, or penumbra, but only a part of it passes through the darkest shade, or umbra. During this type of eclipse, a section of the Moon will darken as it passes into the Earth\u2019s shadow.<\/p>\n
The eclipse will be visible throughout Europe, Asia, Africa, and western Australia, but unfortunately not to us here in North America.<\/p>\n
<\/p>\n
October 29: Conjunction of the Moon and Jupiter<\/h2>\n
The Moon and Jupiter will be at conjunction again this month of October by sharing the same right ascension and passing within 3\u00b008\u2032 of each other.<\/p>\n
At around the same time the two bodies will also make a close approach (appulse) reaching 2\u00b053\u2032 from each other, but not sharing the same right ascension.<\/p>\n
Both bodies will be visible in the constellation Aries with the Moon at apparent magnitude of -12.7 and Jupiter at -2.9. The Moon will be 15 days old or waning gibbous.<\/p>\n
