In 2015, the International Astronomical Union defined the nominal equatorial Jovian radius to remain constant regardless of subsequent improvements in measurement precision of RJ. This constant is defined as exactly:
= 7.1492×107 m
Similarly, the nominal polar Jovian radius is defined to be exactly:
These values correspond to the radius of Jupiter at 1 bar of pressure. The common usage is to refer to the equatorial radius, unless the polar radius is specifically needed.
For comparison, one Solar radius is equivalent to:
400 Lunar radius(RL)
109 Earth radius (REarth)
9.735 Jupiter radius (RJ)
