52381 (1993 HA) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1993 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.
1993 HA orbits the sun every 528 days (1.45 years), coming as close as 1.09 AU and reaching as far as 1.46 AU from the sun. Based on its brightness and the way it reflects light, 1993 HA is probably between 1.740 to 7.780 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of 1993 HA has been observed. It completes a rotation on its axis every 4.11 days.
1993 HA's orbit is 0.17 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.
1993 HA has 10 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|

1993 HA's orbit is determined by observations dating back to April 17, 1993. It was last officially observed on May 31, 2019. The IAU Minor Planet Center records 369 observations used to determine its orbit.
1993 HA can be reached with a journey of 378 days. This trajectory would require a delta-v of 10.304 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 4,012 potential trajectories and launch windows to this asteroid.
