That's true in the sense that there are many others similar to it. Io is the most volcanically active body in the solar system. Even though it is a gas giant, its diameter is less than 10% of the Sun’s. Jupiter is the biggest planet in our solar system. This is because there are numerous planets to go all around. It is made mostly of hydrogen and helium. the smallest planet and the nearest to the sun. The planets in order from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and finally the dwarf planet Pluto.. The Sun is by far the largest object in the solar system. But just what makes Jupiter so … mars. You can't predict a planet's density from its size. Io's surface is covered by sulfur in different colorful forms. One year on Jupiter is the same as 11.8 Earth years. If you’re fascinated by our solar system, then, you’re in luck. As Io travels in its slightly elliptical orbit, Jupiter's immense gravity causes "tides" in the solid surface that rise 300 feet (100 meters) high on Io, generating enough heat for volcanic activity and to drive off any water. Earth is the fourth smallest of the planets—though in terms of the rocky planets, it's the largest—but it's the most dense.Jupiter is the largest planet in the solar system, but it's Saturn—the solar system's second largest planet—that takes the … With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it's the only one known for sure to have liquid water on its surface. 's that allow water to exist as a solid, liquid, & gas. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest). Saturn is the second-largest planet in the solar system. Most people have at least heard about our solar system and the planets in it. Jupiter has a very thick atmosphere. In terms of mass, volume, and surface area, Jupiter is the biggest planet in our Solar System by a wide margin. Saturn is about 9.4 times the size of earth but its density is one-eighth that of our planet. 2nd planet from the sun Earth's sister planet Thick carbon dioxide atmosphere traps heat. A Planet. It is often said that the Sun is an "ordinary" star. Jupiter's Neighbors a celestial body that orbits a star, is large enough to be round, and has cleared it's orbital path ... slow rotation, solid surface, no rings, few moons.
