  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

2022 RD2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 RD2 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.

2022 RD2 orbits the sun every 376 days (1.03 years), coming as close as 1.00 AU and reaching as far as 1.04 AU from the sun. Based on its brightness and the way it reflects light, 2022 RD2 is probably between 0.003 to 0.015 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 RD2's orbit is 0.02 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.

2022 RD2 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Sept. 3, 2022 3,208,904 0.818
Dec. 22, 2022 5,320,731 1.128
Jan. 26, 2044 988,060 1.056
June 25, 2044 1,034,265 0.945
