Revealing the true nature of the gas giant planets in our Solar System is challenging. The masses of Jupiter and Saturn are about 318 and 95 Earth masses, respectively. While they mostly consist of hydrogen and helium, the total mass and distribution of the heavier elements, which reveal ...
As you know, it's believed that Saturn, and all the planets in our solar system coalesced from a swirling cloud of gas some 4.8 billion years ago. However, if the rings are made of leftovers from that process, then they'd also be about 4.8 billion years old. ...
In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order o...
