Key Facts


Comet C/1885 Y1 (Brooks) is an object with a trajectory through the solar system likely originating from the Oort Cloud. NASA JPL has not classified Brooks as potentially hazardous because its orbit does not bring it close to Earth.

Brooks orbits the sun every days ( years), coming as close as -0.00 AU and reaching as far as -244800.00 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

Brooks's orbit is 0.16 AU from Earth's orbit at its closest point. This means that there is an 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

Brooks's orbit is determined by observations dating back to Dec. 29, 1885. It was last officially observed on Feb. 4, 1886. The IAU Minor Planet Center records 6 observations used to determine its orbit.

Accessibility and Exploration

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