Ryloth
this planet, the second world in the Ryloth System, was the homeworld of the Twi'lek race. Located in the Outer Rim Territories, Ryloth orbited its sun in such a way that one side was perpetually lit and the other was locked in the dark. These Bright Lands, where the daytime temperature reached 300 degrees centigrade, were scoured by huge heat storms that whipped around the planet with winds in excess of 500 kilometers per hour. These storms eventually died on the night side, but not before warming the dark side up enough to support minimal life. It was a dry, rocky world with a thin, breathable atmosphere. The Twi'Leks who lived on the planet mined the mineral ryll for various legal and illegal uses throughout the galaxy. Ryloth was orbited by five, red-colored moons. Ryloth's location put it at one end of the Corellian Run, but many spacers noted that it was farther out in the galaxy than even Tatooine. The planet was originally located by Old Republic explorers some 10,000 years before the onset of the Clone Wars, and was one of the first worlds discovered by explorers in the Outer Rim. Note that Platt's Starport Guide indicates that Ryloth had a year that lasted 289 standard days, and that a "day" on the planet lasted some nineteen hours. However, Geonosis and the Outer Rim Worlds indicates that the year on Ryloth lasted 305 standard days, and that its rotational period was the same, thus being truly tide-locked.
