Overview

2018 VB10 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 VB10 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 VB10 orbits the sun every 360 days (0.99 years), coming as close as 0.81 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2018 VB10 is probably between 0.120 to 0.540 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to a football field.

Close Approaches

2018 VB10'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 VB10 has 10 close approaches predicted in the coming decades:

Images and Observations

2018 VB10's orbit is determined by observations dating back to Nov. 14, 2018. It was last officially observed on Nov. 19, 2018. The IAU Minor Planet Center records 66 observations used to determine its orbit.

Accessibility and Exploration

2018 VB10 can be reached with a journey of 354 days. This trajectory would require a delta-v of 10.279 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 4,262 potential trajectories and launch windows to this asteroid.
