Overview

Amor is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Amor 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.

Amor orbits the sun every 971 days (2.66 years), coming as close as 1.08 AU and reaching as far as 2.75 AU from the sun. Amor is about 1.0 kilometers in diameter, making it a small to average asteroid, comparable in size to the Golden Gate Bridge.

Close Approaches

Amor's orbit is 0.11 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

Amor has 11 close approaches predicted in the coming decades:
