Dorrit

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the San Francisco Bay
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Dorrit is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Dorrit as potentially hazardous because its orbit does not bring it close to Earth.

Dorrit orbits the sun every 970 days (2.66 years), coming as close as 1.52 AU and reaching as far as 2.31 AU from the sun. Based on its brightness and the way it reflects light, Dorrit is probably between 5.255 to 11.750 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Dorrit has been observed. It completes a rotation on its axis every 2.57 hours.

Dorrit's spectral type None (Tholen) / Sa (SMASSII) indicates that it is likely to contain and .

No Close Approaches

Dorrit's orbit is 0.62 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

Dorrit's orbit is determined by observations dating back to Nov. 8, 1931. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 3,909 observations used to determine its orbit.

Accessibility and Exploration

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