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 ...
Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune ...
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.
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 ...
The fourth largest of Jupiter’s moons, Europa, while smaller than Earth’s moon, ranks fourth in water volume, estimated to be twice more than on Earth. [2] Latest analysis using data from NASA’s James Webb Space Telescope indicates that the carbon dioxide found on the icy surface of Europa likely originated in the subsurface ocean which ...
