Overview
2022 MM1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2022 MM1 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 MM1 orbits the sun every 363 days (0.99 years), coming as close as 0.66 AU and reaching as far as 1.33 AU from the sun. Based on its brightness and the way it reflects light, 2022 MM1 is probably between 0.019 to 0.085 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2022 MM1's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2022 MM1 has 23 close approaches predicted in the coming decades:

Images and Observations
2022 MM1's orbit is determined by observations dating back to May 21, 2018. It was last officially observed on June 25, 2023. The IAU Minor Planet Center records 39 observations used to determine its orbit.
Accessibility and Exploration
2022 MM1 can be reached with a journey of 434 days. This trajectory would require a delta-v of 10.112 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 5,207 potential trajectories and launch windows to this asteroid.
