2022 SU7 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 SU7 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 SU7 orbits the sun every 372 days (1.02 years), coming as close as 0.83 AU and reaching as far as 1.19 AU from the sun. Based on its brightness and the way it reflects light, 2022 SU7 is probably between 0.004 to 0.017 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2022 SU7's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2022 SU7's orbit is determined by observations dating back to Sept. 23, 2022. It was last officially observed on Sept. 28, 2022. The IAU Minor Planet Center records 37 observations used to determine its orbit.
2022 SU7 can be reached with a journey of 362 days. This trajectory would require a delta-v of 4.551 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 1,853,950 potential trajectories and launch windows to this asteroid.
