Key Facts

Overview

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

Murdin orbits the sun every 1,690 days (4.63 years), coming as close as 2.45 AU and reaching as far as 3.11 AU from the sun. Based on its brightness and the way it reflects light, Murdin is probably between 1.781 to 3.981 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

Murdin's orbit is 1.44 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

Murdin's orbit is determined by observations dating back to Nov. 3, 2000. It was last officially observed on July 30, 2022. The IAU Minor Planet Center records 446 observations used to determine its orbit.

Accessibility and Exploration

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