Overview

312070 (2007 TA19) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2007 TA19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 TA19 orbits the sun every 340 days (0.93 years), coming as close as 0.47 AU and reaching as far as 1.44 AU from the sun. 2007 TA19 is about 0.6 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

2007 TA19's orbit is 0.02 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.

2007 TA19 has 13 close approaches predicted in the coming decades:
