Rogue One : A Star Wars story is a great movie and a prequel to starwars movie series. The planets and the satellites that they show are mapped to real ones. For a change, there is no opening crawl at the start of the movie.  Another big differentiator is a female led story where daughter of an architect tries to help the rebels not to kill the planets. Instead of R2-D2, there is a new droid K-2SO.

A Saturn-sized planet in our own galaxy reminded Nasa scientists so much of the fictional planet that they nicknamed their new find after Tatooine, Luke Skywalker's home planet . Kepler-16b, the planet is located in the constellation Cygnus, some 200 light-years away from Earth.

In 2006, scientists discovered an icy planet that reminded them so much of the rebel base base from The Empire Strikes Back that they nicknamed it Hoth. The planet is officially named OGLE 2005-BLG-390L after the Optical Gravitational Lensing Experiment (OGLE) that found it.  Fictional Hoth (right) is a frozen tundra that briefly serves as a base for the hidden Rebel Alliance. It's also the nickname of real exoplanet OGLE-2005-BLG-390.

While Return of the Jedi's forest moon of Endor and The Force Awakens' Takodana are both full of lush greenery, astrobiologists believe that plant life could take on different colours on alien planets.  In August, the European Southern Observatory announced the discovery of Proxima Centauri b.This planet is just 4 light-years away from Earth and orbits a tiny red star. 

For "Rogue One," imain character Jyn Erso (played by Felicity Jones), the daughter of the architect behind the Death Star, Galen Erso (Mads Mikkelsen). An outsider since her father forced her to run away from home as a young girl when the Empire's director of advanced weapons research, Orson Krennic (Ben Mendelsohn), ordered Galen to return to finish the Death Star, Jyn has grown to only take care of herself. She ignores the flags of the Empire rising across the galaxy, which you can't notice, as she says, "if you don't look up."  When the Rebel Alliance tracks her down with the hopes that she can lead them to Galen, who has sent out a message through a cargo pilot who works for him (Riz Ahmed) that there is a flaw in the Death Star he's created that can destroy it, Jyn realizes her purpose: bringing hope to the Rebels.
