Overview
2022 NR is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 NR 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 NR orbits the sun every 551 days (1.51 years), coming as close as 0.96 AU and reaching as far as 1.67 AU from the sun. Based on its brightness and the way it reflects light, 2022 NR is probably between 0.012 to 0.052 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2022 NR has been observed. It completes a rotation on its axis every 0.07 hours.
Close Approaches
2022 NR'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 NR has 8 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 10, 2022 | 383,998 | 8.298 |
| July 30, 2025 | 15,822,746 | 7.095 |
| Sept. 11, 2028 | 28,129,276 | 7.336 |
| July 1, 2084 | 12,409,431 | 9.954 |
| July 14, 2087 | 4,625,518 | 7.731 |
| Aug. 22, 2090 | 23,841,485 | 7.170 |
| June 27, 2137 | 21,729,203 | 11.460 |
| July 12, 2140 | 1,772,487 | 8.056 |
Images and Observations
2022 NR's orbit is determined by observations dating back to June 29, 2022. It was last officially observed on July 9, 2022. The IAU Minor Planet Center records 159 observations used to determine its orbit.
Accessibility and Exploration
2022 NR can be reached with a journey of 354 days. This trajectory would require a delta-v of 10.701 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 78 potential trajectories and launch windows to this asteroid.
