The combination of the bulge and rotation rate me… One day on Saturn takes 10.7 hours – that is one rotation. About 764 Earths could fit inside Saturn. it’s diameter. Saturn's rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator. In comparison, its polar diameter is only 108,728 km (67,560 miles), or 10 percent smaller, which makes Saturn the most oblate (flattened at the poles) of all the planets in the solar system. But … Saturn is a gas giant because it is predominantly composed of hydrogen and helium. If Earth were the size of a nickel, Saturn would be about as big as a volleyball. In terms of volume and surface area, the numbers get even more impressive! Saturn is a gas-giant planet and therefore does not have a solid surface like Earth’s. If you had a ball that was the size of a dime, Saturn would be a little bigger than a soccer ball. With a radius of 36,183.7 miles (58,232 kilometers), Saturn is 9 times wider than Earth. Saturn is about 75 thousand miles (120,000 km) in diameter and is almost ten times the diameter of Earth. First let’s consider how large Saturn is from one end to the other – i.e. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. For starters, the... Mass and Density… Saturn's diameter, radius and circumference The mean radius of the body of Saturn is 36,184 miles (58,232 kilometers). Gas Giant. Its oblate shape is … From this distance, it takes sunlight 80 minutes to travel from the Sun to Saturn.Orbit and Rotation How Big is Saturn? A bit more on Saturn. Jupiter, Uranus, and Neptune, the other giant planets in the Solar System, are also oblate but to a lesser extent. The equatorial... Volume and Surface Area:. It is the sixth planet from the sun which is about 886 million miles (1.4 billion kilometers) away. Saturn orbits the sun and takes 29 Earth years to do so. Saturn has an equatorial diameter of 120,536 km, 9.44 times that of Earth. Its equatorial and polar radii differ by almost 10%: 60,268 km versus 54,364 km. By this measure, Saturn’s equatorial diameter is 120,536 km (74,898 miles). Diameter:. It lacks a definite surface, though it may have a solid core. In December 2010 the Cassini mission first detected a storm on Saturn which was still raging in June 2011. However, the giant planet … Continue the conversation on That makes it the second largest planet in our Solar System, trailing only Jupiter. From an average distance of 886 million miles (1.4 billion kilometers), Saturn is 9.5 astronomical units away from the Sun.
