Key Facts

Overview

Comet C/1999 K4 (LINEAR) is an object with a medium-length orbit that is highly inclined to the ecliptic plane of the solar system. NASA JPL has not classified LINEAR as potentially hazardous because its orbit does not bring it close to Earth.

LINEAR orbits the sun every 26,200 days (71.73 years), coming as close as 1.44 AU and reaching as far as 33.10 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

LINEAR's orbit is 0.44 AU from Earth's orbit at its closest point. This means that there is a 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

LINEAR's orbit is determined by observations dating back to May 17, 1999. It was last officially observed on May 22, 1999. The IAU Minor Planet Center records 18 observations used to determine its orbit.

Accessibility and Exploration

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