Is there a theoretical size limit for a planet?

[QUOTE="snorkack, post: 6805598, member: 436348"] Not completely wrong. We have multiple possible constraints. We see that Earth, Venus and Mars are big, yet have very little hydrogen. Clearly there was a process separating iron and rock from hydrogen. What are the limits of that process? In Solar system, the biggest chunk of iron and rock is 1 Earth mass (Earth), but the biggest chunk of hydrogen here is just 1 solar mass (sun). We plainly see in sky chunks of up to 100 solar masses (some stars). We would not see quite big chunks of iron and rock. So can we derive what unusually big chunks of rocks and iron would look like, how we could see them and why we cannot? Why do they not form? [/QUOTE]
