WebApr 6, 2024 · Jupiter has many moons with 4 main ones and up to 60 others. Its largest moon is called Ganymede and is bigger than the planet Mercury. One day on Jupiter lasts 10 hours, as it is the fastest rotating planet in our solar system. But it takes 12 Earth years for Jupiter to orbit the Sun. So, one year on Jupiter is the equivalent of 12 here on Earth. WebBecause Mercury rotates three times for every two orbits of the Sun (i.e. has three sidereal days every two years) a solar day on Mercury is equal to two Mercury years or 176 Earth days. While on Venus, a year (224.70 Earth days) is shorter than the sidereal day (243.0 Earth days) which means that the solar day for Venus is 116.67 Earth days. ttc ttf windows
