the planet's name is 2003 UB313, yeh a bit odd lol. it takes 550-odd years for it to make one cycle around the sun. if you were on UB313 and looked in the night sky, the sun would look like any other star out there because of the distance. the temperature is a little bit above 0K, the lowest temperature there can physically be.
dunno, i've always found stuff like this a bit odd since while you're in school, they always try to drill in stuff into your brain.
