Overview

613403 (2006 GB) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2006 GB as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2006 GB orbits the sun every 343 days (0.94 years), coming as close as 0.79 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2006 GB is probably between 0.156 to 0.700 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2006 GB has been observed. It completes a rotation on its axis every 11.83 hours.

Close Approaches

2006 GB'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.

2006 GB has 28 close approaches predicted in the coming decades:

Images and Observations

2006 GB's orbit is determined by observations dating back to April 2, 2006. It was last officially observed on July 24, 2023. The IAU Minor Planet Center records 525 observations used to determine its orbit.

Accessibility and Exploration

2006 GB can be reached with a journey of 354 days. This trajectory would require a delta-v of 8.26 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 48,125 potential trajectories and launch windows to this asteroid.
