Overview

2020 EN is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 EN as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2020 EN orbits the sun every 1,080 days (2.96 years), coming as close as 0.92 AU and reaching as far as 3.20 AU from the sun. Based on its brightness and the way it reflects light, 2020 EN is probably between 0.632 to 1.413 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2020 EN's orbit is 0.05 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.

2020 EN has 6 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 29, 2031 8,135,453 11.925
Oct. 28, 2034 20,962,052 8.990
Dec. 25, 2099 6,781,020 10.858
Oct. 17, 2102 20,873,882 9.489
Dec. 27, 2155 6,383,409 10.962
Oct. 1, 2158 21,520,601 11.850
