Dwarf planet Eris in Cetus

Eris was only discovered in 2005 and is classified as a Scattered Disk Object, with a high orbital inclination of 44 degrees to the plane of the Solar System. It is roughly the same size as Pluto at 1450 miles in diameter, though more massive, and takes 559 years for one orbit around the sun compared to Pluto's 248 years.

This image shows Eris as it was on 18th November 2020, shining at magnitude 18.78 in the constellation Cetus and around 95 AU (Astronomical Units) distant.

Remotely imaged from Spain, using a SBIG STL-6303 camera though a Planewave 12.5 inch CDK reflector.
