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 0.112 to 0.250 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

The rotation of 2018 EB has been observed. It completes a rotation on its axis every 3.16 hours.

Close Approaches

2018 EB's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2018 EB has 25 close approaches predicted in the coming decades:
