The Grand Tack, … WebJun 12, 2012 · The Grand Tack scenario relies on two assumptions: Jupiter formed around the snow line, in the range 2.5 AU to 4.5 AU, and it reversed migration at 1.5 AU. Walsh et al. ( 2011 ) demonstrate that the asteroid belt can survive this migration of Jupiter and Saturn because scattering by Jupiter initially empties the belt when it migrates inwards ...
