Overview

2018 EB is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 EB as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2018 EB orbits the sun every 374 days (1.02 years), coming as close as 1.00 AU and reaching as far as 1.03 AU from the sun. Based on its brightness and the way it reflects light, 2018 EB is probably between 0.111 to 0.248 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

The rotation of 2018 EB has been observed. It completes a rotation on its axis every 1.22 days.

Close Approaches

2018 EB's orbit is 0.01 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 EB has 24 close approaches predicted in the coming decades:
