Key Facts

Overview

Comet 311P/PANSTARRS is an object whose orbit brings it closer to the sun than Jupiter. NASA JPL has not classified 311P/PANSTARRS as potentially hazardous because its orbit does not bring it close to Earth.

311P/PANSTARRS orbits the sun every 1,183 days (3.24 years), coming as close as 1.94 AU and reaching as far as 2.44 AU from the sun.

No Close Approaches

311P/PANSTARRS's orbit is 0.95 AU from Earth's orbit at its closest point. This means that there is an 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

311P/PANSTARRS's orbit is determined by observations dating back to Jan. 17, 2005. It was last officially observed on March 7, 2018. The IAU Minor Planet Center records 191 observations used to determine its orbit.

Accessibility and Exploration

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