Overview

345722 (2007 BG29) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2007 BG29 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.

2007 BG29 orbits the sun every 278 days (0.76 years), coming as close as 0.55 AU and reaching as far as 1.11 AU from the sun. 2007 BG29 is about 0.7 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

Close Approaches

2007 BG29'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.

2007 BG29 has 17 close approaches predicted in the coming decades:
