Multiple Sunsets Like Tatooine

Luke Skywalker’s home planet of Tatooine in Star Wars had two suns, but that’s paltry compared to a Jupiter-like planet 149 light-years from Earth. This planet has three suns, with the main star similar in mass to our own sun. The triple-star system is known as HD 188753. Like Tatooine, the planet there is likely pretty hot – it orbits very close to the main star, completing one orbit every 3.5 days.
