Abstract: Planetary impacts have shaped the surfaces and interiors of planets. They were particularly decisive in the last stage of planetary accretion, as they have eventually formed terrestrial plan
(a) The ejected material provenance for the giant impact event (780-km diameter impactor with velocity of 6.4 km/s). The crustal thickness was assumed to be 40 km. The excavation cavity is the orange
• We provide relationships between impactor size, gravity signal and farside basin size as a function of cooling history and formation time; • Gravity anomalies serve as a measure of basin size as imp
