Question: A planet is orbiting a star when, for no apparent reason, the star's gravity suddenly vanishes. The planet then obeys Newton's First law and heads

A planet is orbiting a star when, for no apparent reason, the star's gravity suddenly vanishes. The planet then obeys Newton's First law and heads outward along a straight line. Is Kepler's second law still obeyed? That is are equal areas swept out in equal intervals of time as the planet moves away
