Key Facts

Overview

Comet C/2016 X1 (Lemmon) is an object whose orbit is approximately between Jupiter and Neptune. NASA JPL has not classified Lemmon as potentially hazardous because its orbit does not bring it close to Earth.

Lemmon orbits the sun every 41,026,202 days (112,323.62 years), coming as close as 7.56 AU and reaching as far as 4648.35 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

Lemmon's orbit is 6.64 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

Lemmon's orbit is determined by observations dating back to Nov. 26, 2016. It was last officially observed on May 2, 2019. The IAU Minor Planet Center records 218 observations used to determine its orbit.

Accessibility and Exploration

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