Overview

234145 (2000 EW70) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 EW70 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 EW70 orbits the sun every 332 days (0.91 years), coming as close as 0.64 AU and reaching as far as 1.24 AU from the sun. 2000 EW70 is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.

The rotation of 2000 EW70 has been observed. It completes a rotation on its axis every 33.00 hours.

Close Approaches

2000 EW70's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2000 EW70 has 25 close approaches predicted in the coming decades:
