Key Facts

Overview

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

Pornwasu orbits the sun every 1,270 days (3.48 years), coming as close as 1.96 AU and reaching as far as 2.64 AU from the sun. Based on its brightness and the way it reflects light, Pornwasu is probably between 1.308 to 2.924 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of Pornwasu has been observed. It completes a rotation on its axis every 87.78 hours.

No Close Approaches

Pornwasu's orbit is 0.97 AU from Earth's orbit at its closest point. This means that there is a 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

Pornwasu's orbit is determined by observations dating back to May 4, 1994. It was last officially observed on May 26, 2023. The IAU Minor Planet Center records 937 observations used to determine its orbit.

Accessibility and Exploration

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