Summarize this article for a 10 year old
Kwangmyŏngsŏng-1 or Gwangmyeongseong-1 (Korean: 광명성 1호, Hanja: 光明星 1號, meaning Bright Star 1) was a satellite allegedly launched by North Korea on 31 August 1998. While the North Korean government claimed that the launch was successful, no objects were ever tracked in orbit from the launch,[1] [self-published source] and outside North Korea it is considered to have been a failure.[2][3] It was the first satellite to be launched as part of the Kwangmyŏngsŏng program, and the first satellite that North Korea attempted to launch.

It was launched from Musudan-ri using a Paektusan rocket, at 03:07 GMT on 31 August 1998, a few days before the 50th anniversary of North Korea's independence from Japan. On 4 September, the Korean Central News Agency announced that the satellite had successfully been placed into low Earth orbit.
The China National Space Administration was involved in the development of Kwangmyŏngsŏng-1, which had a 72-faced polyhedral shape, similar to Dong Fang Hong I, the first Chinese satellite.[4][self-published source] The mass of the satellite is unclear, with estimates ranging from 6 kilograms (13 lb) to 170 kilograms (370 lb).
