Overview

250458 (2004 BO41) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 BO41 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.

2004 BO41 orbits the sun every 375 days (1.03 years), coming as close as 0.52 AU and reaching as far as 1.52 AU from the sun. 2004 BO41 is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2004 BO41 has been observed. It completes a rotation on its axis every 16.19 hours.

Close Approaches

2004 BO41'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.

2004 BO41 has 10 close approaches predicted in the coming decades:
