Overview

387733 (2003 GS) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2003 GS 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.

2003 GS orbits the sun every 308 days (0.84 years), coming as close as 0.70 AU and reaching as far as 1.09 AU from the sun. 2003 GS is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to the U.S. Capitol building.

The rotation of 2003 GS has been observed. It completes a rotation on its axis every 2.47 hours.

Close Approaches

2003 GS's orbit is 0.09 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.

2003 GS has 22 close approaches predicted in the coming decades:

Images and Observations

2003 GS's orbit is determined by observations dating back to April 4, 2003. It was last officially observed on May 3, 2020. The IAU Minor Planet Center records 791 observations used to determine its orbit.

Accessibility and Exploration

2003 GS can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.754 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 28 potential trajectories and launch windows to this asteroid.
