The question, rather, is whether such a planet could have gotten started without a solid planetoid to begin collecting all that gas in the Hunter Pence San Francisco thank you for the memories signature shirt But I will love this first place. Looking at the properties of Jupiter’s gravitational field has led to some interesting findings. In physics class the gravitational force exerted by an object it said to entirely emanate from a point at the center of the object, but that’s just an approximation. In reality, the distribution of mass within a body like Jupiter leads to a certain “shape” of field, and that shape can be roughly viewed by science. It should not necessarily be taken for granted that all gas giants have solid cores, however.
