Abstract: Lecture on suspected gas giant planets, which have been detected in orbit around nearly two dozen nearby stars, their formation either by core accretion or disk instability. Core accretion required several million years or more to form a giant planet in a protoplanetary disk, however, disk instability can form a gas giant protoplanet in a few thousand years.
