Delivery time 2023-11-08 10:04 Twin satellites confirmed by taking pictures at 6-minute intervals… Exploration of asteroids around Jupiter in 2027 (Seoul = Yonhap News) Reporter Lee Joo-young = NASA’s asteroid exploration spacecraft Lucy is flying to explore the ‘Jupiter Trojan asteroids’, a group of asteroids around Jupiter. A unique asteroid with twin satellites has been captured and is attracting attention. A photo of the Dinkinesh asteroid and its twin satellites taken 6 minutes apart. This photo was taken by NASA’s asteroid probe Lucy while flying close to the Dinkinesh asteroid 480 million km away. Among these photos taken on the 1st, a satellite was captured rising like a moon behind the Dinkinesi asteroid on the left, and the photo on the right, taken 6 minutes later, shows that the satellite is in the form of two similarly sized objects attached to each other.

NASA and the Southwest Research Institute (SwRI), in charge of the Lucy project, analyzed photos taken by Lucy as it passed by the Dinkinesi asteroid on the 7th (local time) and found that the asteroid’s satellite is shaped like two rocks of similar size close together. It was revealed that it was. The research team released the first photo of the Dikinesi asteroid taken by Lucy on the 1st on the 4th, followed by the second photo taken 6 minutes following the first photo was taken on the same day. The first photo was taken 435 km away from Dinkinesi by Lucy, which is currently flying 480 million km away from the Earth, and shows a 220m-sized satellite rising like the moon behind the 790m-sized Dinkinesi. Dr. John Spencer of SwRI, deputy director of the Lucy project, said, “As we approached Dinkinesi, we saw strange changes in brightness and got a hint that it might have a moon. But we had no idea that this asteroid system would look so bizarre.” The second photo was taken following Lucy passed the closest point of Dinkinesi and flew another 1,500 km for 6 minutes, 1,630 km away from Dinkinesi. NASA Lucy probe’s Dinkinesh asteroid and satellite images The NASA Lucy probe (white circle) flew along the red line and reached point A, 435 km away from the Dinkinesi asteroid, at 1,630 at 12:55 p.m. on the 1st (Eastern U.S. time). The Dinkinesh asteroid and the satellites orbiting around it were photographed at point B, which was 1 km away. The distance between the two points is approximately 1,500 km, and the difference in shooting time is 6 minutes.

This photo shows the 220m-sized satellites orbiting the Dinkinesi asteroid so close together that they actually look like two similarly sized objects stuck together. Dr Hal Levison of SwRI, the leader of the Lucy project, said: “I never expected a system to look like this. I don’t understand why the two satellites are similar in size. It will be interesting to find out. “He said. The main goal of the Lucy probe is to investigate the ‘Trojan asteroids’, a group of asteroids around Jupiter that have never been explored. It was launched on October 16, 2021, and is scheduled to explore Trojan asteroids orbiting Jupiter from August 2027. Dinkinesi and its moon were the first asteroids explored by Lucy. Lucy is scheduled to fly close to Earth in December 2024 to gain propulsion with the help of Earth’s gravity, and will head to Jupiter following exploring the ‘Donald Johansson’ asteroid in the asteroid belt in 2025.
