Key Facts


175113 (2004 PF115) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2004 PF115 as potentially hazardous because its orbit does not bring it close to Earth.

2004 PF115 orbits the sun every 89,700 days (245.59 years), coming as close as 36.82 AU and reaching as far as 41.62 AU from the sun. Based on its brightness and the way it reflects light, 2004 PF115 is probably between 319.562 to 714.562 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of South Dakota.

No Close Approaches

2004 PF115's orbit is 35.90 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

2004 PF115's orbit is determined by observations dating back to June 4, 1992. It was last officially observed on Nov. 4, 2020. The IAU Minor Planet Center records 279 observations used to determine its orbit.

Accessibility and Exploration

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