But there are still many more waiting to be discovered.<\/li>\n<li><strong>Astronomers used new simulator software called Sorcha<\/strong> to predict that the upcoming Vera C. Rubin Observatory will discover millions of new small solar system objects. And it will observe them in full color, unlike previous surveys.<\/li>\n<li><strong>Rubin will observe our solar system and cosmos for 10 years.<\/strong> It will create a new time-lapse \u201cmovie\u201d of the universe.<\/li>\n<\/ul>\n<h3>Millions of new small solar system objects<\/h3>\n<p>Our solar system is filled with millions of objects, from planets and moons to asteroids and comets. And now astronomers are poised to find millions more. An international team of researchers, led by Queen\u2019s University Belfast in Ireland, have completed a new study showing that the upcoming Vera C. Rubin Observatory in Chile is predicted to reveal millions more small asteroids, comets and other minor planets. The researchers said on June 4, 2025, that Rubin will revolutionize our knowledge about our solar system\u2019s small bodies.<\/p>\n<p>Rubin will spend the next 10 years observing the Southern Hemisphere\u2019s night sky, producing the Legacy Survey of Space and Time (LSST). The LSST will consist of a time-lapse \u201cmovie\u201d of the cosmos. It will also create a dataset that astronomers can use to map the solar system, in new technicolor. As well as objects in our solar system, Rubin will observe pulsating stars and supernova explosions and delve into the mysteries of dark energy and dark matter.<\/p>\n<p>Vera C. Rubin is a new observatory under construction on the Cerro Pach\u00f3n ridge in northern Chile. It is scheduled to begin observations later this year. It includes the fastest-moving telescope, equipped with the world\u2019s largest digital camera with a resolution of 3.2 gigapixels. In fact, a single image from the telescope covers a patch of sky about 45 times the area of the full moon.<\/p>\n<p>In addition, the team also created Sorcha, an innovative new open-source software that the astronomers will use to predict what discoveries Rubin will likely make.<\/p>\n<p>The research team has written a series of new peer-reviewed papers, which have been accepted for publication in <em>The Astronomical Journal<\/em>.

These include asteroids, comets and other minor planets. Overall, these are the numbers predicted:<\/p>\n<ul>\n<li><strong>127,000 near-Earth objects.<\/strong> Those are asteroids and comets that come close to, or intersect with, Earth\u2019s orbit. Currently, about 38,000 are known. Rubin can help astronomers detect more than 70% of potentially hazardous bodies larger than 140 meters that might pose a danger to Earth.<\/li>\n<li><strong>More than 5 million main-belt asteroids.<\/strong> We already know of about 1.4 million bodies in the main asteroid belt between Mars and Jupiter. Now, Rubin will find many more and obtain precise color and rotation data for about one in three of them.<\/li>\n<li><strong>109,000 Jupiter Trojans.<\/strong> Those are bodies that share Jupiter\u2019s orbit, clustered ahead of and behind the planet at stable Lagrange points. Objects at Lagrange points remain in stable positions. Soon, Rubin will increase the number of known Trojans seven-fold.<\/li>\n<li><strong>37,000 trans-Neptunian objects.<\/strong> These objects are way out in the distant Kuiper Belt, where Pluto resides. Rubin will find 10 times as many as astronomers currently know about.<\/li>\n<li><strong>1,500-2,000 Centaurs.<\/strong> These are a bit closer, in the middle of the solar system. They are on short-lived orbits that cross the orbits of the giant planets. Eventually, most of them will be ejected from the solar system entirely. A few, however, will become comets.<\/li>\n<\/ul>\n<p>Meg Schwamb, at Queen\u2019s University Belfast, led the new study. She said:<\/p>\n<blockquote>\n<p>Our knowledge of what objects fill Earth\u2019s solar system is about to expand exponentially and rapidly.<\/p>\n<\/blockquote>\n<figure id=\"attachment_512665\" aria-describedby=\"caption-attachment-512665\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><figcaption id=\"caption-attachment-512665\" class=\"wp-caption-text\">View larger. | Artist\u2019s illustration of an asteroid belt.

Rubin will see the small solar system objects in \u201cnew\u201d color too. Previous solar system surveys have typically used just one-color filter. But Rubin will use multiple color filters.<\/p>\n<p>Co-author Joe Murtagh, also at Queen\u2019s University Belfast, said:<\/p>\n<blockquote>\n<p>With the LSST catalog of solar system objects, our work shows that it will be like going from black-and-white television to brilliant color.<\/p>\n<\/blockquote>\n<figure id=\"attachment_512669\" aria-describedby=\"caption-attachment-512669\" style=\"width: 500px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/earthsky.org\/upl\/2025\/06\/Meg-Schwamb-Queens-University-Belfast.jpg\" alt=\"Smiling woman with long hair and wearing an oval pendant.\" width=\"500\" height=\"666\" class=\"size-full wp-image-512669\" srcset=\"https:\/\/earthsky.org\/upl\/2025\/06\/Meg-Schwamb-Queens-University-Belfast.jpg 500w, https:\/\/earthsky.org\/upl\/2025\/06\/Meg-Schwamb-Queens-University-Belfast-225x300.jpg 225w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\"\/><figcaption id=\"caption-attachment-512669\" class=\"wp-caption-text\">Meg Schwamb at Queen\u2019s University Belfast in Ireland led the new study about Rubin and small solar system bodies.

Using Rubin\u2019s planned observing schedule, it applies assumptions on how Rubin observes. It can then detect astronomical sources in its images to determine the best model of what the solar system and its small bodies look like today. As Schwamb explained:<\/p>\n<blockquote>\n<p>Accurate simulation software like Sorcha is critical. It tells us what Rubin will discover and lets us know how to interpret it.<\/p>\n<\/blockquote>\n<p>Co-author Siegfried Eggl at the University of Illinois Urbana-Champaign added:<\/p>\n<blockquote>\n<p>Only by debiasing LSST\u2019s complex observing pattern can we turn raw detections into a true reflection of the solar system\u2019s history; where the planets formed, and how they migrated over billions of years. Sorcha is a game changer in that respect.<\/p>\n<\/blockquote>\n<p>Since the Sorcha code is open source, you can use it, too. The website also includes simulated catalogs, animations and pre-prints of the published papers.<\/p>\n<figure id=\"attachment_512663\" aria-describedby=\"caption-attachment-512663\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/earthsky.org\/upl\/2025\/06\/Rubin-C-Observatory-night-Chile-July-20-2022.jpg\" alt=\"Large L-shaped building on a rocky mountain top, with mountains in the distance and stars in a dark blue sky above.\" width=\"800\" height=\"537\" class=\"size-full wp-image-512663\" srcset=\"https:\/\/earthsky.org\/upl\/2025\/06\/Rubin-C-Observatory-night-Chile-July-20-2022.jpg 800w, https:\/\/earthsky.org\/upl\/2025\/06\/Rubin-C-Observatory-night-Chile-July-20-2022-300x201.jpg 300w, https:\/\/earthsky.org\/upl\/2025\/06\/Rubin-C-Observatory-night-Chile-July-20-2022-768x516.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\"\/><figcaption id=\"caption-attachment-512663\" class=\"wp-caption-text\">View larger\/ full image. | The Vera C.

As Jake Kurlander at the University of Washington, who led one of the prediction studies, noted:<\/p>\n<blockquote>\n<p>This is what makes Rubin unique: it scans the sky comprehensively and quickly. It took 225 years to detect the first 1.5 million asteroids; we show that Rubin will double that in less than a year.<\/p>\n<\/blockquote>\n<p>Mario Juric, also at the University of Washington, said:<\/p>\n<blockquote>\n<p>Rubin Observatory\u2019s LSST is our once-in-a-generation chance to fill in the missing pieces of our solar system. Our simulations predict that Rubin will expand known small-body populations by factors of 4\u20139x, delivering an unprecedented trove of orbits, colors and light curves. With this data, we\u2019ll be able to rewrite the textbooks of solar system formation and vastly improve our ability to spot \u2013 and potentially deflect \u2013 the asteroids that could threaten Earth.<\/p>\n<\/blockquote>\n<p>Rubin will reveal its first peek at the cosmos at a First Look event on June 23, 2025. Hundreds of venues around the globe will be hosting watch parties that include a public viewing of the live stream.<\/p>\n<p>Bottom line: A new predictive research study said the Vera C.
