420356 Praamzius (provisional designation 2012 BX85) is a trans-Neptunian object from the classical Kuiper belt, located in the outermost region of the Solar System, approximately 190–320 kilometers (120–200 miles) in diameter.
[4][6] It was discovered on 23 January 2012, by astronomers Kazimieras Černis and Richard Boyle with the Vatican's VATT at Mount Graham Observatory in Arizona, United States.
The cold classical Kuiper belt object is a weak dwarf planet candidate and possibly very red in color.
Praamzius is one of the most recently discovered minor planets to receive a numeric designation, confirming it as a distinct body with a well determined orbit.
[4] This would qualify the object as a weak dwarf planet candidate based on the 5-class taxonomic system of American astronomer Michael Brown.
