What is the size of Jupiters Rocky core ?
« on: 13/10/2007 18:54:32 »
Dear Jovian Judges,

This is a planet called Jupiter,



Nice isn't it ?

..according to wiki "it may also have a rocky core of heavier elements"

A few questions If I may.

Would the rocky core have been there from the birth of the planet or would it have been as an accumulation of rocky impacts ?

If it does have a rocky core how big would it be ?..speculations ?...guestimations ?

If for some silly reason the gases were blown away leaving the rocky core...would the rocky core still be Jupiter ?....

Do you think all the gassy planets have rocky cores ?

Here's an article suggesting a core made from something different...

And here's an article outlining the difference between Jupiter & Saturn...

I'm not sure that rocks falling into Jupiter's atmosphere would survive to reach the core. The atmosphere is so deep & dense that any rocks would probably burn up before they reached the centre.

I suppose it's possible that if the rocks were atomised in the atmosphere, the individual atoms may find their way down; but I'll leave further conjecture on that theory to someone who knows what they're talking about.
