Overview

2020 PN1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 PN1 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 PN1 orbits the sun every 365 days (1.00 years), coming as close as 0.87 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2020 PN1 is probably between 0.014 to 0.062 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 PN1's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2020 PN1 has 65 close approaches predicted in the coming decades:
