Overview

2010 TV149 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 TV149 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 TV149 orbits the sun every 809 days (2.21 years), coming as close as 0.82 AU and reaching as far as 2.58 AU from the sun. Based on its brightness and the way it reflects light, 2010 TV149 is probably between 0.479 to 1.072 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

2010 TV149'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 TV149 has 14 close approaches predicted in the coming decades:
