About 2o years ago I was driving back from university with my grandfather and then he mentioned how they found planets around other stars. He found this by watching a program on PBS. The fist few were gas giants close to their star called Hot Jupiters. Between now and then there have been many more planets found from smaller then the Earth to larger than Jupiter. Today around a small star that is cooler than the Sun, Nasa released that 7 planets have been around a star called TRAPPIST-1. Three of these planets are in a zone where liquid water can exists, these zones around stars are called habitable zones or Goldilocks zones. These planets are so close that you could look up and see details of the other planets
