1996 PW is an exceptionally eccentric trans-Neptunian object and a damocloid on an orbit typical of long-period comets but one that showed no sign of cometary activity around the time it was discovered.[8] The unusual object measures approximately 10 kilometers (6 miles) in diameter and has a rotation period of 35.4 hours and likely an elongated shape.[7]
