Overview

142563 (2002 TR69) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2002 TR69 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2002 TR69 orbits the sun every 781 days (2.14 years), coming as close as 1.09 AU and reaching as far as 2.23 AU from the sun. 2002 TR69 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

Close Approaches

2002 TR69's orbit is 0.10 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.

2002 TR69 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 10, 2059 28,457,267 11.745
March 5, 2074 15,409,200 11.716
Feb. 28, 2089 28,162,550 13.109
March 7, 2151 15,583,469 11.650
March 2, 2166 26,451,104 12.957
