Overview

2020 YP is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 YP 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.

2020 YP orbits the sun every 304 days (0.83 years), coming as close as 0.76 AU and reaching as far as 1.01 AU from the sun. Based on its brightness and the way it reflects light, 2020 YP is probably between 0.032 to 0.071 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 YP's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2020 YP has 14 close approaches predicted in the coming decades:
