Kepler-20 (NORAD 56217, COSPAR 2023-054AR) was a CA satellite that re-entered Earth's atmosphere on 19 Sep 2025, launched on 15 Apr 2023 on the Transporter-7 mission. It was operated by KEPLER as part of the Kepler programme. The spacecraft was built by KEPLER/UTIAS on the Cubesat 6U bus, with a mass of 15 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
