Overview

510190 (2011 CX7) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 CX7 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.

2011 CX7 orbits the sun every 541 days (1.48 years), coming as close as 0.88 AU and reaching as far as 1.72 AU from the sun. Based on its brightness and the way it reflects light, 2011 CX7 is probably between 0.206 to 0.461 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2011 CX7's orbit is 0.11 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.

2011 CX7 has 15 close approaches predicted in the coming decades:
