Jedha is a desert planet that features in Rogue One where Jyn Erso and Cassian Andor visit to track down Saw Gerrera who is carry out extreme attacks on the Galactic Empire forces which are not only hurting the Galactic Empire but also the Rebellion. The planet was mined by the Galactic Empire because it was a source of Kyber Crystals which are used by Lightsabres and also by the primary weapon of the Death Star to destroy planets. The planet is not destroyed but the city along with all its inhabitents are destroyed on the orders of Grand Moff Tarkin. The city where the action takes place is the main inhabitents for the planet.
The name is similar to the Saudi Arabian city of Jeddah on the west coast of the country. Both location are desert landscapes.Copyright: Lucasfilm
