Overview

153415 (2001 QP153) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 QP153 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.

2001 QP153 orbits the sun every 307 days (0.84 years), coming as close as 0.70 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2001 QP153 is probably between 1.011 to 2.260 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

Close Approaches

2001 QP153's orbit is 0.07 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2001 QP153 has 14 close approaches predicted in the coming decades:
