Figure 2.2: The distribution of v ∞ for close hyperbolic encounters with <strong>Earth</strong>, with v ∞in km s −1 and the y-axis indicating the normalized probability for each v ∞ bin (Bottke2004, personal communication).tational expediency: q=1.2, 1.4, 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.5, 4.0 and 4.5 R ♁and v ∞ = 8, 12, 16, 20, and 24 km s −1 .Richardson et al. (1998) determined that the orientation of a non-spherical body canhave a significant effect on the outcome of a tidal disruption. Specifically when the leadinglong axis of a body is rotating towards or away the planet, disruption is enhanced orsuppressed respectively. <strong>Near</strong> perigee the equipotential surface of the body is stretched in31
