That's why you couldn't get rocky planets in the early cosmos.

Not exact matches

This scenario naturally produces a planetary system just like our own: small, rocky planets with thin atmospheres close to the star, a Jupiter - like gas giant just beyond the snowline, and the other giants getting progressively smaller at greater distances because they move more slowly through their orbits and take longer to hoover up material.

If there's gas around and the bodies get large enough, perhaps something on the order of 10 Earth masses or so, then you can start pulling some gas in on top of your rocky core and make something that looks like a gas giant planet, like Jupiter.

That's a line, some distance from the sun, where it gets too cold to make rocky planets.

and if they had used a more realistic emissivity for a dry, rocky planet — say 0.88, then they would have got a temperature of 287.58 K which is close enough to what is the existing mean temperature with GH gases that are thus doing no warming at all.
