Key Facts

Overview

Pulliah is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Pulliah as potentially hazardous because its orbit does not bring it close to Earth.

Pulliah orbits the sun every 1,270 days (3.48 years), coming as close as 2.14 AU and reaching as far as 2.44 AU from the sun. Pulliah is about 3.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of Pulliah has been observed. It completes a rotation on its axis every 9.47 hours.

No Close Approaches

Pulliah's orbit is 1.17 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

Pulliah's orbit is determined by observations dating back to Aug. 28, 1986. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 3,589 observations used to determine its orbit.

Accessibility and Exploration

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