Overview
Almeria is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Almeria 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.
Almeria orbits the sun every 756 days (2.07 years), coming as close as 1.16 AU and reaching as far as 2.09 AU from the sun. Based on its brightness and the way it reflects light, Almeria is probably between 0.795 to 1.778 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
The rotation of Almeria has been observed. It completes a rotation on its axis every 21.97 hours.
Close Approaches
Almeria's orbit is 0.17 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.
Almeria has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Feb. 14, 2021 | 29,733,882 | 11.774 |
| Feb. 16, 2139 | 27,761,765 | 11.726 |
| Feb. 16, 2168 | 25,885,400 | 11.637 |
| Feb. 15, 2197 | 25,238,954 | 11.605 |
Images and Observations
Almeria's orbit is determined by observations dating back to Feb. 8, 1992. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 1,661 observations used to determine its orbit.
