Key Facts

Overview

Comet 25D/Neujmin 2 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 25D/Neujmin 2 as potentially hazardous because its orbit does not bring it close to Earth.

25D/Neujmin 2 orbits the sun every 1,983 days (5.43 years), coming as close as 1.34 AU and reaching as far as 4.84 AU from the sun.

No Close Approaches

25D/Neujmin 2's orbit is 0.35 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

25D/Neujmin 2's orbit is determined by observations dating back to March 5, 1916. It was last officially observed on Feb. 10, 1927. The IAU Minor Planet Center records 55 observations used to determine its orbit.

Accessibility and Exploration

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