Overview

2020 GE is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 GE 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 GE orbits the sun every 368 days (1.01 years), coming as close as 0.96 AU and reaching as far as 1.04 AU from the sun. Based on its brightness and the way it reflects light, 2020 GE is probably between 0.041 to 0.190 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 GE'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 GE has 14 close approaches predicted in the coming decades:

Images and Observations

2020 GE's orbit is determined by observations dating back to March 29, 2020. It was last officially observed on April 16, 2020. The IAU Minor Planet Center records 37 observations used to determine its orbit.

Accessibility and Exploration

2020 GE can be reached with a journey of 362 days. This trajectory would require a delta-v of 3.64 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 5,077,734 potential trajectories and launch windows to this asteroid.
