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 0.781 to 1.746 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 29,733,865 11.774
Feb. 16, 2139 27,761,825 11.726
Feb. 16, 2168 25,885,434 11.637
Feb. 15, 2197 25,238,956 11.605

Images and Observations

Almeria's orbit is determined by observations dating back to Feb. 8, 1992. It was last officially observed on July 7, 2021. The IAU Minor Planet Center records 1,152 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
