Damocloids are asteroids such as 5335 Damocles and 1996 PW that have long-period highly eccentric orbits typical of periodic comets such as 1P/Halley, but without showing a cometary coma or tail.
The object 2001 OG108 was thought to be a Damocloid, but as it approached perihelion it began to display cometary activity and was thus renamed Comet C/2001 OG108 (LONEOS).
They are believed to originate from the Oort cloud.
