174567 Varda is a large trans-Neptunian object, discovered on 21 June 2003 by American astronomer Jeffrey A. Larsen using survey images taken with the 0.9-meter Spacewatch telescope at the Kitt Peak National Observatory. As a dynamically hot classical Kuiper belt object, Varda orbits within the Kuiper belt region. Stellar occultations in 2018 show that Varda is likely an oblate spheroid with a flattening of 0.07 and an area equivalent diameter of 740±14 km. Other triaxial ellipsoid shape models remain mathematically unconstrained. The total mass of the binary system is approximately 2.675+0.048−0.049×1020 kg with Varda contributing around 86 to 90% of it. Varda's bulk density estimates remain highly ambiguous. James Webb Space Telescope data shows a surface temperature of 44 K. Abundant frozen carbon dioxide dominates its surface.
