R_polar_jupiter constant wrong value

[jorgepiloto]

🐞 Problem

Just found a small error in the R_polar_jupiter constant from the poliastro.constants.general module. Value should be 6.6854e7 and not 6.6854.

The following code should solve the problem:

R_polar_jupiter = Constant(                                                     
    "R_polar_jupiter",                                                          
     "Jupiter polar radius",                                                     
     6.6854e7,                                                                     
     "m",                                                                        
     10000,                                                                      
     "IAU Working Group on Cartographic Coordinates and Rotational Elements: 2009",
     system="si",                                                                
 )
