Maths of planet radius
« on: December 19, 2017, 04:25:04 AM »
Hello everyone, I'm new here.

I'm curious what equations are used to determine the radius of a planet in US2, particularly gas giants (but I also want to know about rocky planets). I've had trouble finding such equations on the internet. Obviously mass is a parameter, but the rest I'm unsure of. Is a model of hydrostatic equilibrium used?

Thanks, everyone! บอลสเต็ป2

I don't know what model it is, it might even be unique, but I definitely know it's not linear. Higher mass gas giants shink under their own weight while lower mass ones don't.

well, If you were on jupiter(if it had ground) you would be pulled down to the ground, If you were on pluto you would jump high, this is seen with neptune and saturn, just jupiter was in a perfect spot due to the expansion of the protostar and light materials(aka gasses) were thrown in this area so the trend is somewhat alright.

this game somewhat shows it especially with stars and blackholes
