Key Facts

Overview

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

Janesick orbits the sun every 1,190 days (3.26 years), coming as close as 1.40 AU and reaching as far as 2.99 AU from the sun. Janesick is about 7.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Janesick has been observed. It completes a rotation on its axis every 173.40 hours.

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

No Close Approaches

Janesick's orbit is 0.59 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

Janesick's orbit is determined by observations dating back to July 7, 1978. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 3,072 observations used to determine its orbit.

Accessibility and Exploration

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