Gallifrey is The Doctor's home planet. All the other Timelord's originated their, including The Master and The Rani. It was located in the constellation of Kasterborous, 250 million light-years away from Earth. Gallifrey is described as a "buetiful place" by The Doctor, and has 2 suns. Apparntly Gallifrey is a bright orange will colourful sands and lush grass. But, this wonderful homeworld was destroyed by The Daleks, during the great time war between The Daleks and The Timelords. It was a great battle for the planet itself, but The Doctor escaped in his TARDIS. No one won the battle and the planet, along with The Daleks homeworld Skaro, was destroyed. It is reported that the great time war was during The Doctor's eight carnation, but no one actually knows. The Doctor has never went back in time to see it, as crossing time lines is against the universal law. No one knows if he will ever visit.
