It hasn't been seen displaying cometary activity so far.

Unlike the first centaur, 2060 Chiron, Pholus has shown no signs of cometary activity.

Other centaurs such as 52872 Okyrhoe are suspected of showing cometary activity.

A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity.

Observations taken in January and February 2002 showed that the object had developed a small amount of cometary activity as it approached perihelion.

Main-belt comets are bodies orbiting within the main asteroid belt which have shown cometary activity during part of their orbit.

Some comets were first spotted as minor planets, and received a temporary designation accordingly before cometary activity was later discovered.

When it was discovered on 2005 October 24, it showed vigorous cometary activity until 2005 December 27.

Subsequently, around the next perihelion in November 2001, the cometary activity appeared again, and persisted for 5 months.

Several otherwise unremarkable bodies in the outer belt show cometary activity.
