Well i assume that it would have to be nearly arsenic, or gallum for the mass to met the stated requirement.
The defintion of 126,000 miles as a diameter was attributed to the atmosphereic diameter that juptier should have given it current distance from the sun. correct jupiters diameter is not 126,000 miles and so it is assume that juptiter may have lost atomsphere in a magnetic pole reversal or other event, it was also suggested that juptier may have been a small sun that burned its atmosphere off becomeing a gas giant, perhaphs a red dwarf acting as sols compaionion star.
what would you say dragon
