Overview

513138 (2002 CY58) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 CY58 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.

2002 CY58 orbits the sun every 583 days (1.60 years), coming as close as 0.84 AU and reaching as far as 1.89 AU from the sun. Based on its brightness and the way it reflects light, 2002 CY58 is probably between 0.162 to 0.361 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2002 CY58's orbit is 0.06 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.

2002 CY58 has 18 close approaches predicted in the coming decades:
