Overview

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

Huma orbits the sun every 701 days (1.92 years), coming as close as 1.06 AU and reaching as far as 2.03 AU from the sun. Huma is about 0.7 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of Huma has been observed. It completes a rotation on its axis every 10.40 hours.

Close Approaches

Huma's orbit is 0.18 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.

Huma has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Sept. 16, 2082 29,596,751 7.234
Sept. 16, 2130 28,936,385 6.810
Sept. 17, 2178 28,601,188 6.510

Images and Observations

Huma's orbit is determined by observations dating back to June 4, 1986. It was last officially observed on March 3, 2022. The IAU Minor Planet Center records 562 observations used to determine its orbit.

Accessibility and Exploration

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