Facets:
Source sentences:
text: Cometary orbits around Jupiter are unstable, as they will be highly elliptical and likely to be strongly perturbed by the Sun's gravity at apojove (the furthest point on the orbit from the planet).
text: Comets are in unstable orbits that evolve over time due to perturbations and outgassing.
