Overview

2015 TB145 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 TB145 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2015 TB145 orbits the sun every 1,110 days (3.04 years), coming as close as 0.29 AU and reaching as far as 3.91 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2015 TB145 is probably between 0.262 to 0.586 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2015 TB145 has been observed. It completes a rotation on its axis every 2.94 hours.

Close Approaches

2015 TB145's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
