A planet I thought up for an rpg I'm DM-ing. The tidal lock has caused one side to continually face the sun, while the other side is exposed to frigid space. I ran some orbital and thermodynamics calcs, here are a few 'facts':
Mean orbital radius: 9.14 million Km
Year length: 5.32 earth days
Apparent solar size: 17.2 degrees (18 times earth standard)
Recieved radiation (max): 40.5 Kw/m^2
Planetary mean radius: 2140 Km
Maximum surface temperature: 1944 K (easily melts steel)
Minimum surface temperature: 9 k
Update: The "campaign" only lasted about three sessions, but we all had a blast. I was unable to kill anyone in a convincing way, so they escaped the planet, presumably to live long fulfilling lives before dying of old age. There were some tense moments though... Igniting the main fusion drive while buried under three kilometers of hydrogen ice comes to mind. Oh, and the trip to the earthquake wracked girdle zone. And when the remains of the crashed, revived, and crashed again colony vessel was subducted between kilometer long shards of grinding crystalline stone.
