Is there a theoretical size limit for a planet?

[QUOTE="sophiecentaur, post: 6805631, member: 199289"] Praise indeed, young man. :smile: It's always worth considering the actual numbers involved when pushing the envelope. You're right - which is why I was referencing the formation of planetary systems. But the ratio of abundance within the Solar System doesn't appear to actually suggest giant rocky planets. The estimated mass of Jupiter's core is 10-40 Earth Masses but (from magnetic measurements, I assume) there doesn't appear much Iron is in there. As the data about exoplanet systems increases, it will be easier to compare out Solar System with others. So far, the evidence seems to indicate that the lumps of Iron out there are of relatively limited size. I would think that the magnetic field round a really massive iron object would make it stand out because of its resultant interaction with charged particles at great distances - possibly severely affecting its parent star emissions. I guess the OP could usefully search for reports of that sort of thing. [/QUOTE]
