How big is Jupiter? | Space
It’s the largest planet in the solar system, but how big is it? Jupiter? This gas giant is about 318 times more massive The earthaccording to planetary scientist Alan Boss. If the masses of all the other planets in solar system Combined into a “superplanet,” Jupiter would still be two and a half times as massive.
Radius, diameter and circumference
Jupiter has an average radius of 43,440.7 miles (69,911 km). NASA Science. That’s about one tenth of the sun. However, its rotational speed is fast – it rotates once every 9.8 hours, according to the magazine Acta Astronautica – causing it to bulge at the equator, where it has a diameter of 88,846 miles (142,984 km). In contrast, the diameter at the poles is only 83,082 miles (133,708 km). This elongated shape is known as a convex sphere.
Based on Statistics of NASAif you walked around Jupiter’s equator, you would travel 272,946 miles (439,264 km), 10 times more distance around the center line of the Earth.
Because of Jupiter is made of gas, mainly, its surface is considered to be homogeneous. It therefore lacks high and low points – mountains and valleys – such as those found on rocks Land planet.
Density, mass and volume
Known as a giant gasJupiter is made up mainly of hydrogen and helium, according to NASA. It weighs 1.9 x 1027 kg. Despite being significantly more massive than Earth, it is only 1/5 as dense, at 1,326 kg/m3because it is made of gas, not stone.
The volume of Jupiter is 1,431,281,810,739,360 cubic kilometers, 1,321 times that of Earth.
The surface area of this giant planet is 23,713,907,537 square miles, or 6,1419×10ten square kilometers, 120 times more than our planet.
The structure of Jupiter is similar to that of Sunbut it would need 75 times its current mass to undergo the fusion of hydrogen power a staraccording to the magazine Science. Masses of the most massive gas planets found outside the solar system often given about giant planets.
