Roche limit hadd-e Roche Fr.: rayon de Roche The smallest distance at which a → _{M}/ρ_{m})^{1/3},
where R is the radius of the → primary body,
ρ_{M}_{M} is the → density of the
primary, and ρ_{m} is the density of
the secondary body. This formula can also be
expressed as:
d = 1.26 R
(_{m}M_{M}/M_{m})^{1/3}, where
R is the radius of the secondary. As an example,
for the Earth-Moon system, where _{m}R = 6,378 km,
ρ_{M}_{M} = 5.5 g cm^{-3}, and ρ_{m} = 2.5 g cm^{-3}
is 1.68 Earth radii.Named after Edouard Albert Roche (1820-1883), the French astronomer who first calculated
this theoretical limit in 1848; → |
