In terms of volume and surface area, the numbers get even more impressive! For starters, the surface area of Saturn is Still, that is pretty astounding when put into perspective. On the other hand, Saturn has a volume of Again, Jupiter has it beat since Saturn has only What about mass? Looking at the numbers, you may notice that this seems like a bit of a discrepancy. Neptune is the fourth-largest planet in the Solar System.
Neptune has a diameter of The mass of Neptun is equivalent to The diameter of Neptune is four times wider than the diameter of the Earth. Pluto has a diameter of around 2. Pluto has only Charon has 9. In comparison to Earth, the Moon has only 1. The Moon is about one quarter the size of Earth, and it would take around 50 moons to fill the Earth.
Our Moon is, though, the largest moon in the Solar System relative to its parent planet. How Big is the Earth? Earth vs Venus Venus is the sixth-largest planet from the Sun. Earth vs Saturn Saturn , which is the second-largest planet in our Solar System, is a monster in comparison to Earth. Galileo Galilei was the first to see Saturn's rings in , although from his telescope the rings looked more like handles or arms.
Forty five years later, in , Dutch astronomer Christiaan Huygens , who had a more powerful telescope, later proposed that Saturn had a thin, flat ring. As scientists developed better instruments, they continued to learn more about the structure and composition of the rings.
Saturn actually has many rings made of billions of particles of ice and rock, ranging in size from a grain of sugar to the size of a house. The particles are believed to be debris left over from comets, asteroids or shattered moons. A study also suggested the rings may be the carcasses of dwarf planets. The largest ring spans 7, times the diameter of the planet.
The main rings are typically only about 30 feet 9 meters thick, but the Cassini-Huygens spacecraft revealed vertical formations in some of the rings, with particles piling up in bumps and ridges more than 2 miles 3 km high.
The rings are named alphabetically in the order they were discovered. The main rings, working out from the planet, are known as C, B and A. The innermost is the extremely faint D ring, while the outermost to date, revealed in , is so big that it could fit a billion Earths within it.
The Cassini Division, a gap some 2, miles 4, km wide, separates rings B and A. Mysterious spokes have been seen in Saturn's rings, which appear to form and disperse within only a few hours. Scientists have conjectured that these spokes might be composed of electrically charged sheets of dust-size particles created by small meteors impacting the rings, or by electron beams from the planet's lightning.
Voyager 2 made its closest approach to Saturn on Aug. The mission revealed a planet so phenomenal scientists had to go back. Drought is a complicated problem that requires lots of data. Satellites from NASA and its partners help collect that data. Drought Makes its Home on the Range. Gene Roddenberry would have been years old on Aug.
