Overview

363790 (2005 JE46) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 JE46 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 JE46 orbits the sun every 959 days (2.63 years), coming as close as 0.85 AU and reaching as far as 2.95 AU from the sun. Based on its brightness and the way it reflects light, 2005 JE46 is probably between 0.715 to 1.600 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

2005 JE46's orbit is 0.03 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.

2005 JE46 has 11 close approaches predicted in the coming decades:
