2021 GM1 is a near-Earth asteroid which at absolute magnitude 30.4 is the smallest Solar System body observed over multiple years. After it was discovered in April 2021, a precovery position was found for May 2020 which constrains the orbit significantly. Its next close approach to Earth is in 2049.[1]
