2023 GC2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2023 GC2 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.
2023 GC2 orbits the sun every 365 days (1.00 years), coming as close as 0.85 AU and reaching as far as 1.15 AU from the sun. Based on its brightness and the way it reflects light, 2023 GC2 is probably between 0.006 to 0.027 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2023 GC2's orbit is 0.01 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.
2023 GC2 has 12 close approaches predicted in the coming decades:

2023 GC2's orbit is determined by observations dating back to April 14, 2023. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 17 observations used to determine its orbit.
2023 GC2 can be reached with a journey of 378 days. This trajectory would require a delta-v of 5.566 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 558,261 potential trajectories and launch windows to this asteroid.
