Overview

2015 YG is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2015 YG 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.

2015 YG orbits the sun every 236 days (0.65 years), coming as close as 0.38 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2015 YG is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2015 YG'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.

2015 YG has 39 close approaches predicted in the coming decades:
