Overview

2015 DR215 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2015 DR215 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2015 DR215 orbits the sun every 199 days (0.54 years), coming as close as 0.35 AU and reaching as far as 0.98 AU from the sun. Based on its brightness and the way it reflects light, 2015 DR215 is probably between 0.232 to 0.518 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2015 DR215's orbit is 0.04 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.

2015 DR215 has 31 close approaches predicted in the coming decades:
