Key Facts

Overview

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

Janmitchener orbits the sun every 2,070 days (5.67 years), coming as close as 2.74 AU and reaching as far as 3.61 AU from the sun. Janmitchener is about 7.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Janmitchener has been observed. It completes a rotation on its axis every 30.97 hours.

No Close Approaches

Janmitchener's orbit is 1.76 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

Janmitchener's orbit is determined by observations dating back to Nov. 29, 1978. It was last officially observed on Feb. 3, 2023. The IAU Minor Planet Center records 1,544 observations used to determine its orbit.

Accessibility and Exploration

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