Overview

2007 MG is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 MG 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 MG orbits the sun every 526 days (1.44 years), coming as close as 0.68 AU and reaching as far as 1.87 AU from the sun. Based on its brightness and the way it reflects light, 2007 MG is probably between 0.152 to 0.339 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2007 MG's orbit is 0.10 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 MG has 13 close approaches predicted in the coming decades:
