Overview

523818 (2010 SH13) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2010 SH13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 SH13 orbits the sun every 484 days (1.33 years), coming as close as 1.04 AU and reaching as far as 1.37 AU from the sun. Based on its brightness and the way it reflects light, 2010 SH13 is probably between 0.097 to 0.433 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2010 SH13'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.

2010 SH13 has 10 close approaches predicted in the coming decades:

Images and Observations

2010 SH13's orbit is determined by observations dating back to Sept. 27, 2010. It was last officially observed on Nov. 15, 2022. The IAU Minor Planet Center records 147 observations used to determine its orbit.

Accessibility and Exploration

2010 SH13 can be reached with a journey of 354 days. This trajectory would require a delta-v of 11.672 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 5 potential trajectories and launch windows to this asteroid.
