Key Facts

Overview

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

Hawking orbits the sun every 1,234 days (3.38 years), coming as close as 2.09 AU and reaching as far as 2.42 AU from the sun. Hawking is about 2.0 kilometers in diameter, making it larger than most asteroids, comparable in size to Mount Everest.

No Close Approaches

Hawking's orbit is 1.10 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.

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

Images and Observations

Hawking's orbit is determined by observations dating back to Oct. 27, 1978. It was last officially observed on Sept. 6, 2018. The IAU Minor Planet Center records 1,068 observations used to determine its orbit.

Accessibility and Exploration

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