Planetary Variations Interactive (83.0K)
Three main factors determine the atmospheric composition of a body; its own mass, the masses of its constituent gases, and its temperature. Let's look at that last factor on two worlds of almost the same sizes.
There is a marked difference in the atmospheric compositions of the terrestrial and jovian planets. Basically, the jovians are almost nothing but atmosphere. Why?
We are now discussing "planetary variations" not just for planets orbitting the sun, but for those around other stars as well.
Three main factors determine the surface conditions on a planet; its size, mass, and distance from the Sun. Here we study how they could create a living planet elsewhere.
