Jupiter completely rotates on its axis once every 9.9 hours. Jupiter rotates faster than any other planet in the solar system. Determining the rotation speed of Jupiter is complex due to the fact that it is a gaseous planet without many consistent landmarks to track.
Due to the composition of the planet, Jupiter rotates approximately 5 minutes slower at its poles than at its equator. The speed of 9.9 hours is the average for all points on the planet. Jupiter completes an orbit around the sun once every 11.8 Earth years, or 4,332 Earth days. Jupiter is comprised almost entirely of hydrogen and helium.Learn More
The shape of Earth's orbit is an ellipse, which resembles a stretched circle. Earth's orbit lies on the plane of the ecliptic, an imaginary plane in which the sun and the planets move. Earth revolves around the sun in a period of 365 days.Full Answer >
According to NASA, none of the planets in the solar system are known to have exactly four moons. It is noted that Jupiter has four large moons, known as the Galilean Satellites, but the gas giant might have up to 46 additional smaller moons.Full Answer >
According to NASA, Jupiter's moon, Ganymede, is the largest moon in the solar system. It has a diameter of 2,631 kilometers. Ganymede is larger than both Pluto and Mercury and is 3/4 the size of Mars. Unlike many other moons, Ganymede has a core that generates a substantial magnetic field.Full Answer >
Mars makes a complete rotation on its axis every 24 hours and 37 minutes. The length of a day on Mars is only 39 minutes and 35 seconds longer than the length of a day on Earth.Full Answer >
