Hár is a double-ringed crater approximately 120 kilometres (75 mi) in diameter[3]: 19027 [4] located southwest of the craterTindr.[1]: 843 Its inner ring is rugged and hummocky, and it is surrounded by a "platform" of hilly terrain.[5]: 5–9 Occupying the center of the crater is a very prominent dome about 82 kilometres (51 mi) in diameter, offset to the west from the crater center.[1]: 843 The dome's origin is unclear, but it may have formed from the uplift of icy material below the crater's center after its formativeimpact event.[4] Many of Hár's features are muted due to ejecta from Tindr, and a series of radiatingcrater chains from Tindr cut across Hár's structure.[5]: 9
