Overview
2023 GM is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 GM as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2023 GM orbits the sun every 1,180 days (3.23 years), coming as close as 0.65 AU and reaching as far as 3.73 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2023 GM is probably between 0.080 to 0.179 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2023 GM's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2023 GM has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 17, 2023 | 3,235,375 | 20.087 |
| Oct. 11, 2026 | 19,147,167 | 24.512 |
| Oct. 6, 2094 | 7,777,817 | 21.991 |
Images and Observations
2023 GM's orbit is determined by observations dating back to April 9, 2023. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 194 observations used to determine its orbit.
