hello,
the only planet perk at the moment is the fishing hole on Relcore. 

How ever,
on each planet there is a shrine that only the residents of that planet can go to. 
Each shrine has the ability to give certain creatu from its planet a special "blessed" effect and special items. 

For example, if you lived on Scria you can go to the Scria shrine and potentially get an effect on one of your pets (if that pet is found on Scria) but you couldn't visit the Relcore shrine. 

You can use planet candles to switch planets for 24hours or you can use a Planet visa to permanently swap planets.
