Was Jupiter ever a solid planet?
Question Date: 2015-09-24
Answer 1:

No. Jupiter is the type example of what is called a GAS GIANT planet. It is almost all hydrogen and helium. There is some other stuff there but that stuff in concentrated in its core, but surrounding the dense core of Jupiter, is a huge envelop of gas, mostly hydrogen and helium. You can't stand on the surface of Jupiter because it is just mainly a bigball of gas.

Answer 2:

Judging by the great distance from the sun that Jupiter formed, it is likely that Jupiter was never a solid planet. During the formation of Jupiter, the distance from the sun made it so that solar winds (winds created by the sun) had little impact blowing away light elements, such as hydrogen and helium, allowing them to clump together easily to form a planet composed of mostly gas! Some scientists today believe that Jupiter does have an extremely hot molten core, while others believe it could just be solid rock.

Maybe one day when you are a scientist, you can help decide!

Answer 3:

So far as we know, Jupiter has always been a ball of gas. Jupiter is thought to have a solid, rocky core, but most of the mass is atmosphere.
