\nThe Japanese space agency (JAXA) just shared an image from the Hayabusa2 mission to asteroid Torifune. On July 5, 2026, the space probe flew within 6.2 miles (10 km) of the asteroid and sent back the image above. The asteroid appears to be what astronomers call a contact binary<\/em>, or 2 asteroids stuck together. Just days earlier, the Chinese space agency also made a flyby of a different asteroid, 2016 HO3 Kamo\u2019oalewa. See the pic below. These 2 asteroid flybys came within 3 days of each other.

2 asteroid flybys yield new closeup images<\/h3>\n
Space agencies from both China and Japan have just shared images from flybys of two different asteroids in our solar system. On July 2, 2026, China\u2019s Tianwen-2 probe flew past asteroid Kamo\u2019oalewa from a distance of just 12.5 miles (20 km). Then on July 5, 2026, Japan\u2019s Hayabusa2 flew past asteroid Torifune from a mere 6.2 miles (10 km) distant.<\/p>\n
Both space agencies caught images of the asteroids. Kamo\u2019oalewa might be a chunk of the moon ejected in a giant impact. And Torifune revealed itself to be two rubble piles joined together, or what astronomers call a contact binary<\/em>.<\/p>\n

On July 6, 2026, the China National Space Administration said: <\/p>\n
\n
The Tianwen-2 probe has arrived at its target asteroid and begun scientific exploration.<\/p>\n<\/blockquote>\n
Tianwen-2\u2019s target is the asteroid Kamo\u2019oalewa, which is a near-Earth asteroid. The asteroid has a strange orbit that keeps it in unison with Earth. This resonant orbit makes it a quasi-satellite of Earth. A 2024 study showed Kamo\u2019oalewa might have once been a part of the moon that blasted off during an impact that formed the lunar crater Giordano Bruno.<\/p>\n
China\u2019s mission to the asteroid began back on May 29, 2025, with the launch of Tianwen-2. After a journey of what the space agency called about 400 days and 1 billion kilometers (621 million miles), Tianwen-2 will now: <\/p>\n
\n
\u2026 conduct more detailed scientific explorations to obtain information on the asteroid\u2019s shape, material composition, and internal structure, providing support for preparations for sampling.<\/p>\n<\/blockquote>\nThe China National Space Administration said on July 6, 2026, that it had recently captured this image of the asteroid Kamo\u2019oalewa. Tianwen-2 took this image on July 2, 2026. Image via China National Space Administration.<\/figcaption><\/figure>\n
Flyby of asteroid Torifune<\/h3>\n
Hayabusa2\u2019s journey to Torifune has taken much longer. The mission launched to space in December 2014. At that time, its target was the asteroid Ryugu. In 2020, Hayabusa2 rendezvoused with Ryugu and took samples that it sent back to Earth. Analysis of the samples show they are rich in primitive organic material.<\/p>\n
After Ryugu, JAXA sent the Hayabusa2 probe on an extended mission to Torifune. The probe arrived at 18:30 Japan Standard Time on July 5, 2026. Hayabusa2 made several observations during its flyby. JAXA is still acquiring this data, so expect more revelations about the asteroid to come!<\/p>\n
But Hayabusa2\u2019s extended mission is not over. After a couple swings past Earth, the space probe is headed for the tiny asteroid 1998 KY26. The asteroid is just 11 meters (36 feet) in diameter. Hayabusa2 should arrive at the asteroid in 2031.<\/p>\n
Bottom line: Japanese and Chinese space agencies both completed asteroid flybys in early July, 2026. See the closeup images here.<\/p>\n
