Zijin Mountain Observatory newly discovered two near -earth planets

Recently, the International Small Star Center issued an announcement to confirm that the Zijin Mountain Observatory of the Chinese Academy of Sciences was newly discovered on July 23 and 24, two near -ground planets -2022 OS1 and 2022 on1. The two asteroids were observed by the Celestial Telescope of the Celestial Observation Station of Zijin Mountain Observatory. At this point, the telescope found a total of 32 near -earth planets.

(2022 OS1)

The asteroid 2022 OS1 was observed for the first time on July 23. At that time, the brightness of the view was about 20.9, and the speed was 0.895 degrees/day. The estimated diameter reached 230m. The asteroid 2022 On1 was observed for the first time on July 24. At that time, the brightness of the view was about 20.5, and the speed was 0.681 degrees/day. The estimated diameter was about 45m. The speed of the two near -ground asteroids is much higher than that of the asteroids of the ordinary main main stars. By sharing data to drive the follow -up observation of domestic and foreign observation equipment, its orbit parameters have been determined, and two AMOR -type small planets have been confirmed.

It is understood that the Celestial Telescope of Zijin Mountain Observatory is the only dedicated device at present in my country nearly land monitoring, and it is also the only backbone equipment for my country to join the international asteroid early warning network to carry out data sharing. Improved the ability to monitor and early warning in my country's near -ground stars has laid a solid foundation.
