I want this planet to be very earth-like on all aspects except for its size and the day-night cycle. The circumference is three times greater than the earth's circumference. The day-night cycle lasts 48 hours.
With that I want to have the same temperature variation for the corresponding hour here on earth. e.g. Noon at that planet should feel the same as noon here on earth. As well as midnight, and so on.
I don't know about tidal locking and all that but I don't mind any celestial bodies and don't really mind how big the moon should be. Of course, since this is a fantasy world, I know I can have anything I want and just blame it all on magic or whatever. But I at least want it to have enough consistency or be realistic enough as not to be absurd.
