Overview

2020 GE1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 GE1 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 GE1 orbits the sun every 363 days (0.99 years), coming as close as 0.91 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2020 GE1 is probably between 0.007 to 0.030 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 GE1's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2020 GE1 has 30 close approaches predicted in the coming decades:

Images and Observations

2020 GE1's orbit is determined by observations dating back to April 4, 2020. It was last officially observed on April 16, 2020. The IAU Minor Planet Center records 90 observations used to determine its orbit.

Accessibility and Exploration

2020 GE1 can be reached with a journey of 362 days. This trajectory would require a delta-v of 4.761 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 1,520,051 potential trajectories and launch windows to this asteroid.
