Overview

2020 KR is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 KR 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 KR orbits the sun every 624 days (1.71 years), coming as close as 0.78 AU and reaching as far as 2.08 AU from the sun. Based on its brightness and the way it reflects light, 2020 KR is probably between 0.006 to 0.014 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 KR'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 KR has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 20, 2020 397,481 13.771
Oct. 19, 2025 15,893,879 11.799

Images and Observations

2020 KR's orbit is determined by observations dating back to May 16, 2020. It was last officially observed on May 20, 2020. The IAU Minor Planet Center records 33 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
