Overview

2014 HS124 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 HS124 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.

2014 HS124 orbits the sun every 573 days (1.57 years), coming as close as 0.95 AU and reaching as far as 1.75 AU from the sun. Based on its brightness and the way it reflects light, 2014 HS124 is probably between 0.046 to 0.205 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2014 HS124's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2014 HS124 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
April 22, 2025 4,101,367 8.875
May 3, 2050 7,856,888 7.276
April 14, 2097 18,420,595 11.304
April 20, 2144 9,062,680 9.707

Images and Observations

2014 HS124's orbit is determined by observations dating back to April 25, 2014. It was last officially observed on Oct. 15, 2014. The IAU Minor Planet Center records 33 observations used to determine its orbit.

Accessibility and Exploration

2014 HS124 can be reached with a journey of 354 days. This trajectory would require a delta-v of 11.101 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 54 potential trajectories and launch windows to this asteroid.
