Key Facts

Overview

Robinbock is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Robinbock as potentially hazardous because its orbit does not bring it close to Earth.

Robinbock orbits the sun every 1,610 days (4.41 years), coming as close as 1.98 AU and reaching as far as 3.41 AU from the sun. Robinbock is about 7.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

Robinbock's orbit is 0.98 AU from Earth's orbit at its closest point. This means that there is a very 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

Robinbock's orbit is determined by observations dating back to June 30, 1998. It was last officially observed on June 6, 2023. The IAU Minor Planet Center records 2,005 observations used to determine its orbit.

Accessibility and Exploration

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