Answer to Question 1

False

Answer to Question 2

In planetology, the heat of formation is the heat released by infalling matter during the formation of a planetary body. The heat of formation was tremendous for the Jovian planets. Jupiter must have grown hot enough to glow with a luminosity of about 1 percent that of the present Sun. However, because it never got hot enough to start nuclear fusion as a star would, it never generated its own energy. Jupiter is still hot inside. In fact, both Jupiter and Saturn radiate more heat than they absorb from the Sun, so they are evidently still cooling.
