Jupiter radius (RJ or RJup) is the unit of radius equal to the total radius of the planet Jupiter (71,492 km (44,423 mi), 11.2 Earth mass; one Earth radius equals 0.08921 Jupiter radius). Jupiter radius is used to mainly describe the radii and extrasolar planets. It is also used in describing brown dwarfs. One Jupiter radius can be converted to related units: * 41 Lunar radius (RL) * 11.209 Earth radius (R⊕) * 0.102719 Solar radius (R☉) In comparison, one Solar radius is equivalent to: * 400 Lunar radius(RL) * 109 Earth radius (R⊕) * 9.735 Jupiter radius (RJ)
