(20000) Varuna I is a hypothetical moon of Varuna indicated to possibly exist by photometric observations led by Estela Fernández-Valenzuela along with colleagues in 2019. However, Varuna B is believed to orbit between 1,300 and 2,000 km above Varuna, making resolving it with space-based telescopes impossible as the angular distance is smaller than the resolution of current space-based telescopes. Through the use of a Lomb Periodogram, the rotation of Varuna I was determined to be around 11 hours, 58 minutes, 54 seconds, and 840 milliseconds.
