Overview

2010 HA is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2010 HA 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.

2010 HA orbits the sun every 343 days (0.94 years), coming as close as 0.77 AU and reaching as far as 1.15 AU from the sun. 2010 HA is about 0.0 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.

Close Approaches

2010 HA's orbit is 0.03 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.

2010 HA has 33 close approaches predicted in the coming decades:

Images and Observations

2010 HA's orbit is determined by observations dating back to April 16, 2010. It was last officially observed on July 21, 2011. The IAU Minor Planet Center records 62 observations used to determine its orbit.

Accessibility and Exploration

2010 HA can be reached with a journey of 370 days. This trajectory would require a delta-v of 6.319 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 603,711 potential trajectories and launch windows to this asteroid.
