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]
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
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 completes an orbit every 11.86 years.
The largest planet in the solar system will take center stage in the night sky this week as it appears brighter than any other point in 2021, making it a great opportunity to spot the planet ...

Jupiter passes its neighbor Saturn in their respective laps around the sun every 20 years. Astronomers say so-called conjunctions between the two largest planets in our solar system aren't ...
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low-boiling point materials (), rather than rock or other solid matter, but massive solid planets can also exist.
A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. The planet is roughly the same diameter as Jupiter, but with six times the mass.
