Key Facts

Overview

110P/Hartley 3 is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 110P/Hartley 3 as potentially hazardous because its orbit does not bring it close to Earth.

110P/Hartley 3 orbits the sun every 2,500 days (6.84 years), coming as close as 2.46 AU and reaching as far as 4.74 AU from the sun. 110P/Hartley 3 is about 4.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 110P/Hartley 3 has been observed. It completes a rotation on its axis every 10.15 hours.

No Close Approaches

110P/Hartley 3's orbit is 1.48 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

110P/Hartley 3's orbit is determined by observations dating back to Aug. 11, 2013. It was last officially observed on May 13, 2023. The IAU Minor Planet Center records 2,416 observations used to determine its orbit.

Accessibility and Exploration

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