Overview
2022 RC7 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 RC7 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 RC7 orbits the sun every 291 days (0.80 years), coming as close as 0.61 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2022 RC7 is probably between 0.037 to 0.166 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2022 RC7'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 RC7 has 19 close approaches predicted in the coming decades:

Images and Observations
2022 RC7's orbit is determined by observations dating back to Sept. 15, 2022. It was last officially observed on Oct. 22, 2022. The IAU Minor Planet Center records 29 observations used to determine its orbit.
Accessibility and Exploration
2022 RC7 can be reached with a journey of 346 days. This trajectory would require a delta-v of 9.158 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 38,247 potential trajectories and launch windows to this asteroid.
