Key Facts

Overview

574372 (2010 JO179) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2010 JO179 as potentially hazardous because its orbit does not bring it close to Earth.

2010 JO179 orbits the sun every 250,000 days (684.46 years), coming as close as 39.21 AU and reaching as far as 116.03 AU from the sun. Based on its brightness and the way it reflects light, 2010 JO179 is probably between 439.091 to 981.838 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Japan.

No Close Approaches

2010 JO179's orbit is 38.20 AU from Earth's orbit at its closest point. This means that there is an extremely 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

2010 JO179's orbit is determined by observations dating back to Feb. 4, 1951. It was last officially observed on June 19, 2023. The IAU Minor Planet Center records 169 observations used to determine its orbit.

Accessibility and Exploration

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