Little is known about Varuna. It has a rotational period of approximately 3.17 hours (or 6.34 hours, depending on whether the light curve is single or double-peaked). It has a density of approximately 1 g/cm3 (as dense as water), which implies that it may not be a fully solid body .
It is named after the Hindu god Varuna. It previously had the systematic name 2000 WR106.
