Key Facts


269278 (2008 RH108) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2008 RH108 as potentially hazardous because its orbit does not bring it close to Earth.

2008 RH108 orbits the sun every 2,500 days (6.84 years), coming as close as 3.34 AU and reaching as far as 3.87 AU from the sun. 2008 RH108 is about 5.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

2008 RH108's orbit is 2.35 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2008 RH108's orbit is determined by observations dating back to Sept. 23, 2001. It was last officially observed on Oct. 24, 2021. The IAU Minor Planet Center records 203 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
