Key Facts

Overview

84P/Giclas is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 84P/Giclas as potentially hazardous because its orbit does not bring it close to Earth.

84P/Giclas orbits the sun every 2,540 days (6.95 years), coming as close as 1.84 AU and reaching as far as 5.44 AU from the sun. 84P/Giclas is about 1.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

84P/Giclas's orbit is 0.86 AU from Earth's orbit at its closest point. This means that there is a very 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

84P/Giclas's orbit is determined by observations dating back to Sept. 3, 1978. It was last officially observed on March 18, 2021. The IAU Minor Planet Center records 1,745 observations used to determine its orbit.

Accessibility and Exploration

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