I want to be special and different so for hottest I'm saying Remo for a couple of reasons. It is the closest planet to the star in Antares, and the planet description says Remo has an "extreme surface temperature". The star in Antares is also blue, and blue stars are the hottest type of stars by far making it much hotter than the star in Vega which is orange/red, so Remo is hotter than Dante.

Coldest is Iga, furthest planet from the Gemini stars, the planet description says it is an "incredibly cold planet" and even visiting it to mine for minerals can't be done because of the extreme temperatures. Colder than Aurora since the planet description for Aurora says human civilizations have been living there for a long time.
