Let us start by counting planets.
Our solar system has nine planets in it (including the dwarf planet Pluto).
Our solar system is a part of the Milky Way galaxy. Many attempts have been made to estimate the star count of the Milky Way. Some scientist estimate only 50 billion. Others estimate up to 600 billion. For the purpose of this example I will use 250 billion (It's somewhat in the middle).
There have also been multiple attempts to estimate the amount of galaxies in our universe; these have ranged from 100 billion to 500 billion. Once again I'll use 250 as a nice middle-ish number.
So assuming there are 250 billion galaxies with 250 billion stars we should have, in total 62,500 billion stars. Now multiply that by nine for all the planets orbiting each star. And we get 562500000000000.
That is 562 trillion, 500 billion planets (a very rough estimate could be a lot more or less)
With that many planets in our universe it's not that amazing that our planet has the right temperature and chemicals that are capable of supporting life.
