It is named after The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, which discovered three of the planets announced in May 2016. The TRAPPIST-1 system is relatively close to us at about 40 light-years from Earth. This also means that they have a chance of supporting life as we know it. Three of the seven planets are within the star’s habitable zone, which means that they are in an area where rocky planets have the highest likelihood of having liquid water. Welcome, TRAPPIST-1 system! NASA announced yesterday the discovery of seven Earth-sized planets orbiting the ultra-cool dwarf star, TRAPPIST-1.Ĭheck out the new simulation of the TRAPPIST-1 system in Universe Sandbox ²: Run Steam to update to Alpha 19.6, or buy Universe Sandbox ² via our website or the Steam Store.
