Overview
2020 GE3 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 GE3 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.
2020 GE3 orbits the sun every 313 days (0.86 years), coming as close as 0.69 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2020 GE3 is probably between 0.010 to 0.047 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2020 GE3's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2020 GE3 has 9 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| May 4, 2020 | 7,322,362 | 5.234 |
| May 9, 2026 | 4,254,604 | 5.951 |

Images and Observations
2020 GE3's orbit is determined by observations dating back to April 15, 2020. It was last officially observed on April 27, 2020. The IAU Minor Planet Center records 27 observations used to determine its orbit.
Accessibility and Exploration
2020 GE3 can be reached with a journey of 346 days. This trajectory would require a delta-v of 7.202 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 218,716 potential trajectories and launch windows to this asteroid.
