Overview

416195 (2002 TR190) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 TR190 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 TR190 orbits the sun every 408 days (1.12 years), coming as close as 0.90 AU and reaching as far as 1.25 AU from the sun. Based on its brightness and the way it reflects light, 2002 TR190 is probably between 0.344 to 0.769 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.

Close Approaches

2002 TR190'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.

2002 TR190 has 22 close approaches predicted in the coming decades:
