Overview

2013 TT135 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 TT135 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 TT135 orbits the sun every 1,150 days (3.15 years), coming as close as 0.86 AU and reaching as far as 3.43 AU from the sun. Based on its brightness and the way it reflects light, 2013 TT135 is probably between 0.111 to 0.248 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2013 TT135'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.

2013 TT135 has 8 close approaches predicted in the coming decades:
