Overview

153195 (2000 WB1) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 WB1 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.

2000 WB1 orbits the sun every 542 days (1.48 years), coming as close as 0.50 AU and reaching as far as 2.11 AU from the sun. 2000 WB1 is about 1.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.

Close Approaches

2000 WB1's orbit is 0.09 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.

2000 WB1 has 9 close approaches predicted in the coming decades:
