Hathor is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified Hathor as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Hathor orbits the sun every 283 days (0.77 years), coming as close as 0.46 AU and reaching as far as 1.22 AU from the sun. Hathor is about 0.3 kilometers in diameter, making it a small to average asteroid, comparable in size to a football field.
The rotation of Hathor has been observed. It completes a rotation on its axis every 3.35 hours.
Hathor's spectral type CSU (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .
Hathor's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
Hathor has 27 close approaches predicted in the coming decades:
