Key Facts

Overview

2013 HA is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2013 HA as potentially hazardous because its orbit does not bring it close to Earth.

2013 HA orbits the sun every 3,530 days (9.66 years), coming as close as 1.72 AU and reaching as far as 7.36 AU from the sun. Based on its brightness and the way it reflects light, 2013 HA is probably between 1.272 to 2.845 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2013 HA's orbit is 0.73 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2013 HA's orbit is determined by observations dating back to Jan. 18, 2013. It was last officially observed on June 22, 2013. The IAU Minor Planet Center records 79 observations used to determine its orbit.

Accessibility and Exploration

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