Key Facts

Overview

Comet C/1846 J1 (Brorsen) is an object whose orbit does not match any defined comet orbit class. NASA JPL has not classified Brorsen as potentially hazardous because its orbit does not bring it close to Earth.

Brorsen orbits the sun every 197,000 days (539.36 years), coming as close as 0.63 AU and reaching as far as 131.59 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

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

Images and Observations

Brorsen's orbit is determined by observations dating back to May 2, 1846. It was last officially observed on June 12, 1846. The IAU Minor Planet Center records 170 observations used to determine its orbit.

Accessibility and Exploration

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