Overview

153201 (2000 WO107) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 WO107 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 WO107 orbits the sun every 318 days (0.87 years), coming as close as 0.20 AU and reaching as far as 1.62 AU from the sun. Its orbit is highly elliptical. 2000 WO107 is about 0.5 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

2000 WO107's spectral type None (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

Close Approaches

2000 WO107's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2000 WO107 has 28 close approaches predicted in the coming decades:
