Key Facts

Overview

Comet 452P/Sheppard-Jewitt is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 452P/Sheppard-Jewitt as potentially hazardous because its orbit does not bring it close to Earth.

452P/Sheppard-Jewitt orbits the sun every 7,160 days (19.60 years), coming as close as 4.16 AU and reaching as far as 10.38 AU from the sun.

No Close Approaches

452P/Sheppard-Jewitt's orbit is 3.17 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

452P/Sheppard-Jewitt's orbit is determined by observations dating back to Feb. 2, 2003. It was last officially observed on April 18, 2023. The IAU Minor Planet Center records 218 observations used to determine its orbit.

Accessibility and Exploration

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