1. Australia's PM just got booted out of office before the election. Haha
2. Astronomers estimate there are hundreds of planets (not by definition) exactly like Pluto or bigger, near Pluto or a bit further out, also orbiting the sun.
3. ~5 bodies are known to have WATER in our solar system alone! Europa, Moon, Mars (used to for certain, salt deposits), Earth, Venus (used to be a twin earth with water, none anymore). There are ~200 billion stars in our galaxy and ~100 billion galaxies in the VISIBLE universe....
4. Astronomers estimate that each star has on average two planets orbiting it (estimated through observation of star wobble).
5. Astronomers think there is a high probability of life on Europa and on Uranus. They both likely have some type of ocean under its crust.
