For example, the Hill radius of the Earth is 0.01 au and the Roche limit is au, a factor of ∼78.5 difference. For an Earth-analog in a compact system with a semimajor axis of 0.05 au, the Hill radius shrinks to au, which results in a factor of ∼4.5 difference with the Roche … WebThe Roche lobe, Roche limit, and Roche sphere are named after the FrenchastronomerÉdouard Roche.
