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]
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.
The "Mars problem" is a conflict between some simulations of the formation of the terrestrial planets which end with a 0.5–1.0 M E planet in its region, much larger than the actual mass of Mars: 0.107 M E, when begun with planetesimals distributed throughout the inner Solar System. Jupiter's grand tack resolves the Mars problem by limiting ...
The sun, Earth and Jupiter will nearly align perfectly in the solar system on Monday, Sept. 26, during an event that happens once every 13 months called the Jupiter opposition.
Jupiter on Saturday will shine at its brightest for the year, as Earth’s orbit swings our planet between Jupiter and the sun. Weather permitting, the gas giant will not only be brighter than ...
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
