Xantoras is a minshara-class planet, the homeworld of the Xantorans. The planet is known for it's geological formations, and it's historically unstable governments.
History
The Xantoran government has been known to change hands every few years for a long time prior to the 2150s. The government in place in the late 2140s and early 2150s however was overthrown my a militant group in March of 2152. The new militant group were xenophobic, and believed that aliens shouldn't be allowed on their planet. The previous government had let many aliens on the planet, so the new government instituted a deadline for all off worlders to leave or they would be imprisoned, and probably executed.
The Denobulan government had sent a team of three scientists to study the rare and unique speleothems that had formed in the large underground tunnels several weeks prior. The team was out of communication range when the new government took hold, so the Denobula Science Academy couldn't contact them. The nearest Denobulan starship was several days away, so they asked the Human ship Enterprise to retrieve them.
The Enterprise sent an away team to climb down the large caverns to retrieve them, given a 3 day deadline. (ENT: "The Breach")
Geology
The geology on Xantoras is quite extraordinary.
