Overview

2018 AV2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 AV2 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 AV2 orbits the sun every 382 days (1.04 years), coming as close as 1.00 AU and reaching as far as 1.06 AU from the sun. Based on its brightness and the way it reflects light, 2018 AV2 is probably between 0.032 to 0.140 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2018 AV2's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2018 AV2 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
July 10, 2037 6,558,393 0.769
April 29, 2057 4,745,870 0.484
April 19, 2078 4,508,414 0.452
Feb. 5, 2099 5,355,050 0.606

Images and Observations

2018 AV2's orbit is determined by observations dating back to Dec. 12, 2017. It was last officially observed on March 10, 2018. The IAU Minor Planet Center records 102 observations used to determine its orbit.

Accessibility and Exploration

2018 AV2 can be reached with a journey of 450 days. This trajectory would require a delta-v of 3.905 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 2,714,570 potential trajectories and launch windows to this asteroid.
