We can not see its solid surface,but know its 15 times bigger than the

an idea if a rock is 3 times bigger than Earth we would see it as a

Earth's is about 25 miles up?? * Does Jupiter have a stratisphere? Is

Like to add Good physics is showing me that Jupiter's atmosphere is
raining down elements onto its solid surface adding size to it at a
very fast rate.How much more density does Jupiter need to shine(star
like) I would think a lot If our debula was twice as dense the Sun
would have a twin. I believe life on a rock planet with two stars
evolving around each other would mean no life. Bert
