Abstract The formation of the Moon from the debris of a slow and grazing giant impact of a Mars-sized impactor on the proto-Earth ( Cameron and Ward [1976] . Lunar Planet. Sci. Conf.; Canup and Asphaug [2001]. Nature 412, 708) is widely accepted today. We present an alternative scenario with a hit-and-run collision (Asphaug [2010]. Chem. Erde 70, 199) with a fractionally increased impact velocity and a steeper impact angle.

The Origin of the Moon Within a Terrestrial Synestia (2018, background): “A range of alternative impact models have been proposed (Canup, 2012; Ćuk & Stewart, 2012; Reufer et al., 2012; Rufu et al., 2017), but each calls upon an additional process or a fortunate coincidence to better explain the Earth-Moon system.”
Water delivery and giant impacts in the 'Grand Tack' scenario (2014, unknown): “…head-on) with V 1 < 4 km = s. Newer simulations suggest that range of acceptable impact conditions may in fact be much larger, as C´uk and Stewart (2012), Canup (2012), and Reufer et al. (2012) found a range of impactor masses ﬁve times as broad with possible impact velocities up to 1 : 3 V esc .”
Evidence for Mo isotope fractionation in the solar nebula and during planetary differentiation (2014, background): “According to the giant impact hypothesis, the Moon predominantly consists of silicate mantle material derived from the impactor (Canup, 2004) and/or the proto-Earth (Canup, 2012; Cuk and Stewart, 2012; Reufer et al., 2012).”
