Key Facts


C/1080 P1 is a large comet with an extremely long orbital period, likely originating from the Oort Cloud. NASA JPL has not classified C/1080 P1 as potentially hazardous because its orbit does not bring it close to Earth.

C/1080 P1 orbits the sun every 0 days (0.00 years), coming as close as 0.00 AU and reaching as far as 0.00 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, C/1080 P1 is probably between 2658.000 to 5943.469 kilometers in diameter, making it the largest asteroid/dwarf planet, very roughly comparable in size to the U.S. state of Alaska.

No Close Approaches

C/1080 P1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

C/1080 P1's orbit is determined by observations dating back to Aug. 10, 1080. It was last officially observed on Aug. 27, 1080. The IAU Minor Planet Center records 4 observations used to determine its orbit.

Accessibility and Exploration

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