- Classified as a Near Earth Asteroid (NEA)
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2020 OP is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 OP 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 OP orbits the sun every 275 days (0.75 years), coming as close as 0.49 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2020 OP is probably between 0.056 to 0.125 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2020 OP's orbit is 0.13 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.
2020 OP has 19 close approaches predicted in the coming decades:
