    A Jupiter day is 0.41354 as long as our day or about 10 hours. The year is 4332.71 earth days long or about 12 earth years. A month is determined by the revolution of our moon around the earth. Jupiter has many moons so it does not have months like we do.

    The Jovian day is 9.925 Earth hours in length

    The Jovian year is 11.862 Earth years in length

    Earth overtakes Jupiter every 398.9 days as it orbits the Sun, a duration called the synodic period. As it does so, Jupiter appears to undergo retrograde motion with respect to the background stars. That is, for a period of time Jupiter seems to move backward in the night sky, performing a looping motion.

    The word month derives from the word moon so each of Jove's 63 companion satellites would have its own individual month length,

    And as you might expect those orbiting closest to the planet have the shortest months and those furthest away have the longest months (they both have further to go and go more slowly). The biggest four, known since Galileo trained his telescope on them in January 1610, are all quite close in, at positions 5-8 inclusive,

    The other rotation period that is of interest is that of the Great Red Spot, Jupiter's best known feature, a persistent anticyclonic storm located 22° south of the equator that is larger than Earth. It is known to have been in existence since at least 1831 and possibly since 1665.

    Mathematical models suggest that the storm is stable and may be a permanent feature of the planet. The storm is large enough to be visible through Earth-based telescopes.

    The oval object rotates counterclockwise, with a period of about 6 days. The Great Red Spot's dimensions are 24–40,000 km × 12–14,000 km. It is large enough to contain two or three planets of Earth's diameter,

    It's because Juno is going to orbit the sun for the first two years before fly back to Earth where it will use the Earth for a gravitational tug to fling to Jupiter which will take 3 years.

    a day on jupiter is about what he said

  • 1 decade ago

    a day is 24hours, and month is 28 to 31 days depending on what month it is and a years is 365 days. The length of time does not change relative to where you are.

    Comes from the Roman king of the gods.

    Visited by

    Pioneer 11, Viking, Galileo and others The fifth planet in our solar system is also the largest planet in our system, both in size and mass. Jupiter's diameter of over 85,000 miles is almost twelve times that of Earth and its mass is well over twice as much as all the rest of the planets put together.

    These facts make it appropriate that the planet is named after the king of all the other gods in ancient Roman mythology.

    Jupiter is also the first of the gas planets in our system. A gas planet is one that does not have a solid surface like Earth. Instead, you can think of Jupiter, as well as the rest of the gas planets, as being a giant ball of mostly hydrogen and helium. Scientists believe that Jupiter has a small rocky core at its center, but even the core of this giant planet is much larger than our Earth.

    Jupiter's size not only makes it the largest planet in our solar system, it has also helped us explore the outer planets. Scientists have used the planet's gravity to accelerate spacecraft and send them one their way to Saturn, Uranus and Neptune.

    Ruler of the Night Skies


    A picture of Jupiter from the Cassini probe.

    Jupiter's extremely large size has made it a favorite observation subject for professional and amateur astronomers ever since Galileo used his first primitive telescope almost four hundred years ago.

    Using even a small telescope, you are able to see the distinctive color bands of Jupiter's atmosphere as well as the four large Galilean moons. Using a medium-sized telescope, you should be able to see the Great Red spot just south of Jupiter's equator. In fact, you can see the four Galilean moons of Jupiter using just a good pair of binoculars.

    You can check the Sky Maps section here at Astronomy for Kids. If Jupiter is visible during the current month, we will tell you where and when to see it.

    A Miniature Solar System

    Jupiter's Moons

    The moons of Jupiter.

    Considering that Jupiter is by far the largest planet in our solar system, it is only fitting that it also has the largest number of moons. The four large Galilean moons, along with at least fifty-seven smaller moons, some of which haven't even been named yet, make up what looks like a small scale solar system.

    The four Galilean moons are both easy to see with a small telescope and are fascinating subjects in their own right. Ganymede, the largest of Jupiter's moons, is larger than the planets Pluto and Mercury. Europa apparently has an ocean under its icy surface and tiny Io has many active volcanoes.

    The Great Red Spot

    Great Red Spot

    The Great Red Spot of Jupiter.

    Jupiter's Great Red Spot is one feature of our solar system that almost everyone is at least somewhat familiar with. This red spot is actually a huge storm that has been raging on Jupiter for at least 400 years.

    Although the Great Red Spot is the most famous feature of Jupiter, it is just one part of the complex atmosphere of the giant planet. The distinctive color bands that we see in pictures of Jupiter are a result of very high winds, the makeup of the planet's atmosphere and the planet's high rotation speed.

    A "day" on Jupiter is just a little over ten hours long, which means that not only is Jupiter huge, but it rotates very fast on its axis. Click on the link at right to learn more about the planet's fascinating atmosphere.

    Comet Shoemaker-Levy 9 Hits Jupiter!


    A comet hits Jupiter!.

    In July of 1994, something occurred in our solar system that only happens at most once every several thousand years. Over a period of about a week, pieces of comet Shoemaker-Levy 9 crashed into Jupiter.

    This was the first time in history that we were able to see and closely study such a spectacular event. Telescopes around the world, as well as the Hubble Space Telescope watched in awe as fragment after fragment of the comet hit the planet, leaving scars in the clouds that remained visible for over a year. It was a very exciting time. Click on the link at right to learn more about this extremely rare event.

    Jupiter's Rings

    Jupiter's Rings

    The rings of Jupiter.

    As the Voyager spacecrafts traveled through our solar system, they sent back many pictures things we expected to see, and even more images that were a complete surprise. One of the many new facts we learned from these missions was that Jupiter has rings. Of course we had known that Saturn had rings for several hundred years, but the discovery of rings around Jupiter was completely unexpected.

    It turned out that all of the gas planets have rings, but we didn't even suspect this until Voyager sent back the pictures. You can learn more about the very faint rings around Jupiter by clicking on the link at right
