Overview
152787 (1999 TB10) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1999 TB10 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.
1999 TB10 orbits the sun every 581 days (1.59 years), coming as close as 1.05 AU and reaching as far as 1.68 AU from the sun. Based on its brightness and the way it reflects light, 1999 TB10 is probably between 0.486 to 1.087 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
1999 TB10'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.
1999 TB10 has 7 close approaches predicted in the coming decades:
