this isn't for vizzy, just normal calculations for my planet building shenanigans
i need to have the mass of the celestial body so i can use mass and radius for the gravity using a calculator i've found (idk if the calculator is accurate, but if it isn't and you have a better one, then please tell me)
the radius is given, and for density i can just look up the average composition and density of similar celestial bodies and base it off of that
so yeah, how get mass from those two values

    yeah, school always overexxagerated planets by saying "they're egg/lemon/potato shaped" even tho it's like a few kilometer difference so for any normal person it'd just be spherical if viewed from space

    in real life, all the planets are slight oblate spheres

    thankfully, we don't have to worry about that in simplerockets 2 :D

    I got 4/3 times Pi times radius cubed ...... but they actually have spherical volume calculators online if you serch for em!

    i think you can get the volume by this:

    volume = (planet’s radius x 2) cubed

    can you give the calculation to get volume from radius?

    Just remember that in planet studio radius is given in meters (not kilometers)
    And density can vary quite a bit depending on what the planet/moon is comprised of. Earth and Venus have density’s over 5 grams per cubic cm whereas the moon and mars have densities around 3.5 g/cm3. Ice moons mostly comprised of water (like Callisto or Triton) have even smaller densities of less then 2 g/cm3

    Ok so density = mass divided by its volume
    So … mass is density multiplied by volume right?
    You can easily get volume using the radius
