Key Facts

Overview

Comet 198P/ODAS is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 198P/ODAS as potentially hazardous because its orbit does not bring it close to Earth.

198P/ODAS orbits the sun every 2,480 days (6.79 years), coming as close as 1.98 AU and reaching as far as 5.19 AU from the sun.

No Close Approaches

198P/ODAS's orbit is 0.99 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

198P/ODAS's orbit is determined by observations dating back to Dec. 15, 1998. It was last officially observed on Dec. 25, 2018. The IAU Minor Planet Center records 200 observations used to determine its orbit.

Accessibility and Exploration

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