Overview

418900 (2009 BE2) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 BE2 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.

2009 BE2 orbits the sun every 711 days (1.95 years), coming as close as 1.01 AU and reaching as far as 2.11 AU from the sun. Based on its brightness and the way it reflects light, 2009 BE2 is probably between 0.384 to 0.859 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2009 BE2's orbit is 0.06 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.

2009 BE2 has 6 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 26, 2019 15,327,636 15.197
June 28, 2056 23,858,496 16.231
June 12, 2058 27,856,180 12.881
June 16, 2095 18,280,190 13.145
June 17, 2132 15,742,389 13.265
June 16, 2169 21,190,471 13.052
