Planets between Gas Giants and size A

[BlackBat242]

"Super Earths"... solid planets much larger than Earth:

My math is a bit rusty, and I already have a headache, so could someone please calculate the diameter for the following planets (assuming a density of 1 [Earth standard])?

mass compared to Earth:
4.2X
6.7X
7.5X
9.4X
22X
30X

Earth is size 8
Neptune (small gas giant) is size 30, Uranus is size 33
Saturn (large gas giant) is size 75, Jupiter is size 89

The CT planet-generation system stops at size 10... then jumps to the gas giants. These would fit in between the two, and require a new set of rules.

More options for planet generation... and places for high-G species to live.

These are my answers:
Mass Size
4.2 12.91
6.7 15.08
7.5 15.66
9.4 16.88
22 22.42
30 24.86

only problem is that the density and size wont relate directly to mass but they will relate to eachother quite a lot and determine the general characteristics of the planet

if the density and mass were higher than earth, the surface might be graphite or other wierder substances rather than silica based rocks we are used to

And I heard a rumour that mass really starts compressing, so much so that panthalassic worlds show up around size 12 or 13, and after that you've actually got the "cold" GGs.

Or something.

Side note - Neptune is only 17 Earth-masses... (Jupiter is 317e).

Warning - this table may be out of date now...

...and it seems to be a pretty low point to start the SGGs, doesn't it...

Interesting...

Where did you get that table?
