Overview

2018 WV1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 WV1 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 collision.

2018 WV1 orbits the sun every 387 days (1.06 years), coming as close as 0.98 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2018 WV1 is probably between 0.02 to 0.07 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus.

Close Approaches

2018 WV1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2018 WV1 has 18 close approaches predicted in the coming decades:

Images and Observations

2018 WV1's orbit is determined by observations dating back to Nov. 29, 2018. It was last officially observed on Dec. 13, 2018. The IAU Minor Planet Center records 90 observations used to determine its orbit.

Accessibility and Exploration

2018 WV1 can be reached with a journey of 370 days. This trajectory would require a delta-v of 3.94 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 1,274,011 potential trajectories and launch windows to this asteroid.
