Overview
2022 GN5 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 GN5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2022 GN5 orbits the sun every 726 days (1.99 years), coming as close as 0.94 AU and reaching as far as 2.22 AU from the sun. Based on its brightness and the way it reflects light, 2022 GN5 is probably between 0.500 to 1.117 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2022 GN5'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 GN5 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 30, 2078 | 27,873,351 | 21.912 |
| Oct. 26, 2080 | 17,014,088 | 20.717 |
| Oct. 23, 2082 | 7,637,390 | 19.770 |
| Oct. 20, 2084 | 4,146,141 | 19.055 |
| Oct. 17, 2086 | 12,343,135 | 18.410 |
| Oct. 13, 2088 | 22,413,996 | 17.922 |
Images and Observations
2022 GN5's orbit is determined by observations dating back to March 21, 2010. It was last officially observed on May 19, 2022. The IAU Minor Planet Center records 74 observations used to determine its orbit.
