Overview

2014 EQ49 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 EQ49 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 EQ49 orbits the sun every 449 days (1.23 years), coming as close as 0.91 AU and reaching as far as 1.39 AU from the sun. 2014 EQ49 is about 0.4 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.

Close Approaches

2014 EQ49'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.

2014 EQ49 has 12 close approaches predicted in the coming decades:
