Key Facts

Overview

Comet P/2008 Y12 (SOHO) is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified SOHO as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

SOHO orbits the sun every 1,970 days (5.39 years), coming as close as 0.07 AU and reaching as far as 6.09 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

SOHO's orbit is 0.04 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

SOHO's orbit is determined by observations dating back to Dec. 21, 2008. It was last officially observed on May 17, 2014. The IAU Minor Planet Center records 76 observations used to determine its orbit.

Accessibility and Exploration

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