Overview
477519 (2010 DJ56) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 DJ56 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2010 DJ56 orbits the sun every 510 days (1.40 years), coming as close as 0.94 AU and reaching as far as 1.56 AU from the sun. 2010 DJ56 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 DJ56'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.
2010 DJ56 has 8 close approaches predicted in the coming decades:
