TrES-4b

At 1.7 times the size of Jupiter, TrES-4b is the largest planet discovered so far. However, despite its size, this planet is only as dense as balsa wood. About 0.2 grams per cubic centimeter. This makes the planet somewhat of an anomaly. Because of its enormous mass and gravity, the planet should be much denser. The planet is located 1,400 light-years away orbiting around its star GSC 02620-00648. Little else is known about the planet.
