Key Facts

Overview

10P/Tempel 2 is a relatively small comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 10P/Tempel 2 as potentially hazardous because its orbit does not bring it close to Earth.

10P/Tempel 2 orbits the sun every 1,962 days (5.37 years), coming as close as 1.42 AU and reaching as far as 4.71 AU from the sun. 10P/Tempel 2 is about 10.6 kilometers in diameter, making it larger than most asteroids, comparable in size to the city of Boston.

The rotation of 10P/Tempel 2 has been observed. It completes a rotation on its axis every 8.93 days.

No Close Approaches

10P/Tempel 2's orbit is 0.41 AU from Earth's orbit at its closest point. This means that there is an 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

10P/Tempel 2's orbit is determined by observations dating back to March 7, 2003. It was last officially observed on March 7, 2019. The IAU Minor Planet Center records 3,479 observations used to determine its orbit.

Accessibility and Exploration

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