Key Facts

Overview

Comet Ikeya-Zhang is an object whose orbit does not match any defined comet orbit class. NASA JPL has not classified Ikeya-Zhang as potentially hazardous because its orbit does not bring it close to Earth.

Ikeya-Zhang orbits the sun every 133,868 days (366.51 years), coming as close as 0.51 AU and reaching as far as 101.92 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

Ikeya-Zhang's orbit is 0.33 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

Ikeya-Zhang's orbit is determined by observations dating back to Feb. 3, 1661. It was last officially observed on Oct. 2, 2002. The IAU Minor Planet Center records 1,784 observations used to determine its orbit.

Accessibility and Exploration

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