The Jupiter radius or Jovian radius (R J or R Jup) has a value of 71,492 km (44,423 mi), or 11.2 Earth radii (R 🜨) [2] (one Earth radius equals 0.08921 R J). The Jupiter radius is a unit of length used in astronomy to describe the radii of gas giants and some exoplanets. It is also used in describing brown dwarfs.
Jupiter is the only planet whose barycentre with the Sun lies outside the volume of the Sun, though by 7% of the Sun's radius. [130] [131] The average distance between Jupiter and the Sun is 778 million km (5.20 AU) and it
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Callisto is the outermost of the four Galilean moons of Jupiter. It orbits at a distance of approximately 1,880,000 km (26.3 times the 71,492 km radius of Jupiter itself). [3] This is significantly larger than the orbital radius—1,070,000 km—of the next-closest Galilean satellite, Ganymede.
Radius Jupiter radii (Jupiter = 1) Radius km (mi) Notes EBLM J0555-57Ab: 2017-0.084 0.84 60,000 km (37,000 mi) This star has a size comparable to that of Saturn.
Jupiter’s striking Great Red Spot has puzzled astronomers for years. Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere.
Radius Jupiter radii (Jupiter = 1) Radius km (mi) Notes 1 EBLM J0555-57Ab: 0.084 0.84 59,000 km (37,000 mi) This star is slightly larger than the planet Saturn.
Its outer edge is located at a radius of about 129,000 km (1.806 R J;R J = equatorial radius of Jupiter or 71,398 km) and coincides with the orbit of Jupiter's smallest inner satellite, Adrastea. [2] [5] Its inner edge is not marked by any satellite and is located at about 122,500 km (1.72 R J). [2] Thus the width of the main ring is around ...
