Overview

528159 (2008 HS3) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2008 HS3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2008 HS3 orbits the sun every 573 days (1.57 years), coming as close as 1.05 AU and reaching as far as 1.65 AU from the sun. Based on its brightness and the way it reflects light, 2008 HS3 is probably between 0.087 to 0.388 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

The rotation of 2008 HS3 has been observed. It completes a rotation on its axis every 10.68 hours.

Close Approaches

2008 HS3's orbit is 0.04 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.

2008 HS3 has 10 close approaches predicted in the coming decades:

Images and Observations

2008 HS3's orbit is determined by observations dating back to April 30, 2008. It was last officially observed on Aug. 10, 2019. The IAU Minor Planet Center records 1,141 observations used to determine its orbit.

Accessibility and Exploration

2008 HS3 can be reached with a journey of 370 days. This trajectory would require a delta-v of 11.329 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 33 potential trajectories and launch windows to this asteroid.
