Overview

468727 (2010 JE87) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2010 JE87 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 JE87 orbits the sun every 314 days (0.86 years), coming as close as 0.51 AU and reaching as far as 1.30 AU from the sun. 2010 JE87 is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to a football field.

Close Approaches

2010 JE87's orbit is 0.04 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.

2010 JE87 has 13 close approaches predicted in the coming decades:
