10. There Are Thousands Of Other Planets Out There
We have eight, or nine (depending on who you ask) planets in our Solar System. However, outside of our Solar System there are thousands of other planets. The extra-solar planets or exo-planets are in orbit around another star. So far we have confirmed about 2,000 new worlds, with another 3000 awaiting confirmation. Scientists are looking to a star’s goldilocks zone for planets that may be habitable, just like the Earth. The majority of planets discovered so far are hot gas giant planets like Saturn and Jupiter.
