Overview

2018 VP1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 VP1 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 VP1 orbits the sun every 731 days (2.00 years), coming as close as 0.91 AU and reaching as far as 2.27 AU from the sun. Based on its brightness and the way it reflects light, 2018 VP1 is probably between 0.002 to 0.004 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2018 VP1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2018 VP1 has 1 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Nov. 2, 2020 419,130 9.711

NASA Sentry has assessed impact risk for 3 very close approach scenarios. Here are the top scenarios ordered by probability of impact:

Date Distance from Earth (km) Distance Error (km) Probability of Impact (%) Impact Energy (Mt)
Nov. 2, 2020 4,994.76 ±0.61 0.40780 0.0004192
Nov. 2, 2025 4,615.98 ±0.68 0.00003 0.0004192
Nov. 2, 2025 5,360.70 ±0.58 0.00003 0.0004193
