Size of Jupiter compared to Earth and Earth's Moon. Jupiter is about ten times larger than Earth (11.209 R 🜨) and smaller than the Sun (0.102 76 R ☉). Jupiter's mass is 318 times that of Earth; [2] 2.5 times that of all the other planets in the Solar System combined.
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]
Jupiter was known to astronomers of ancient times. [1] The Romans named it after their god Jupiter. [2] When viewed from Earth, Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, [3] and making it on average the third-brightest object in the night sky after the Moon and Venus.
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.
It’s 15 times the distance from its star than Earth is to the sun. Scientists had long suspected a big planet circled this star 12 light-years away, but not this massive or far from its star. A ...
The total mass of heavy elements other than hydrogen and helium in the planet is between 11 and 45 M E. [11] The bulk of the hydrogen on Jupiter is solid hydrogen. [12] Evidence suggests that Jupiter contains a central dense core. If so, the mass of the core is predicted to be no larger than about 12 M E. The exact mass of the core is uncertain ...
I don’t think a lot of people know that all four giant planets in our solar system have rings; Saturn’s are by far the most obvious, but Jupiter, Uranus, and Neptune own a set themselves.
The mass ratio of this planet with its star is more than 100 times greater than that of Earth and the sun. ... to host planets much larger than Earth. ... be similar in size and composition to ...
