Overview

2022 RO is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2022 RO 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 RO orbits the sun every 1,590 days (4.35 years), coming as close as 1.07 AU and reaching as far as 4.28 AU from the sun. Based on its brightness and the way it reflects light, 2022 RO is probably between 0.031 to 0.069 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 RO's orbit is 0.12 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 RO has 1 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Sept. 22, 2022 17,964,162 9.147

Images and Observations

2022 RO's orbit is determined by observations dating back to Aug. 30, 2022. It was last officially observed on Sept. 3, 2022. The IAU Minor Planet Center records 17 observations used to determine its orbit.

Accessibility and Exploration

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