Overview
2022 GT3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 GT3 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 GT3 orbits the sun every 373 days (1.02 years), coming as close as 0.84 AU and reaching as far as 1.19 AU from the sun. Based on its brightness and the way it reflects light, 2022 GT3 is probably between 0.011 to 0.051 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2022 GT3's orbit is 0.04 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 GT3 has 11 close approaches predicted in the coming decades:

Images and Observations
2022 GT3's orbit is determined by observations dating back to March 31, 2022. It was last officially observed on April 22, 2022. The IAU Minor Planet Center records 45 observations used to determine its orbit.
Accessibility and Exploration
2022 GT3 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.521 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 195 potential trajectories and launch windows to this asteroid.
