Key Facts


2020 PJ75 is a mid-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2020 PJ75 as potentially hazardous because its orbit does not bring it close to Earth.

2020 PJ75 orbits the sun every 12,200 days (33.40 years), coming as close as 4.54 AU and reaching as far as 16.16 AU from the sun. Based on its brightness and the way it reflects light, 2020 PJ75 is probably between 2.982 to 6.669 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

2020 PJ75's orbit is 3.56 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

2020 PJ75's orbit is determined by observations dating back to Aug. 9, 2020. It was last officially observed on March 1, 2022. The IAU Minor Planet Center records 87 observations used to determine its orbit.

Accessibility and Exploration

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