2019 YM is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 YM 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.
2019 YM orbits the sun every 1,160 days (3.18 years), coming as close as 0.70 AU and reaching as far as 3.61 AU from the sun. Based on its brightness and the way it reflects light, 2019 YM is probably between 0.017 to 0.038 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 YM'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.
2019 YM has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Dec. 21, 2019 | 2,126,542 | 17.137 |
| May 26, 2023 | 20,060,090 | 21.731 |
| May 22, 2058 | 11,634,568 | 19.865 |
NASA Sentry has assessed impact risk for 2 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| Dec. 21, 2117 | 0.00009 | 0.717 |
| Dec. 20, 2041 | 0.00000 | 0.7053 |
2019 YM's orbit is determined by observations dating back to Dec. 19, 2019. It was last officially observed on Dec. 21, 2019. The IAU Minor Planet Center records 31 observations used to determine its orbit.
