2018 GE is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 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.
2018 GE orbits the sun every 324 days (0.89 years), coming as close as 0.83 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2018 GE is probably between 0.006 to 0.025 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 GE's orbit is 0.01 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.
2018 GE has 8 close approaches predicted in the coming decades:

NASA Sentry has assessed impact risk for 2 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| May 23, 2111 | 0.00002 | 0.02513 |
| June 17, 2111 | 0.00000 | 0.02512 |
2018 GE's orbit is determined by observations dating back to April 5, 2018. It was last officially observed on April 23, 2018. The IAU Minor Planet Center records 44 observations used to determine its orbit.
2018 GE can be reached with a journey of 450 days. This trajectory would require a delta-v of 5.006 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 795,549 potential trajectories and launch windows to this asteroid.
