How long are years on jupiter

Mars and Earth are always moving. So, if we want to land a robotic explorer on Mars, we have to understand how Earth and Mars orbit the Sun.

Watch this video to learn more about the Martian year. How Long is a Year on Other Planets? The Short Answer:. Here is how long it takes each of the planets in our solar system to orbit around the Sun in Earth days : Mercury : 88 days Venus : days Earth : days Mars : days Jupiter : 4, days Saturn : 10, days Uranus : 30, days Neptune : 60, days.

In addition to being different in terms of their sizes, composition and atmospheres from Earth, they also differ considerably in terms of their orbits. Whereas those closest to the Sun have rapid transits, and therefore comparatively short years, those farther away can take many Earth to complete a single orbit.

This is certainly the case when it comes to Jupiter, the Solar System largest and most massive planet. Given its considerable distance from the Sun, Jupiter spends the equivalent of almost twelve Earth years completing a single circuit of our Sun. Orbiting at this distance is part of what allows Jupiter to maintain its gaseous nature, and led to its formation and peculiar composition. Jupiter orbits the Sun at an average distance semi-major axis of ,, km 5.

At this distance, Jupiter takes The picture below shows the planets in their orbits on the orbital plane. You have to look carefully to see our home. The four inner planets Mercury, Venus, Earth and Mars are in the tiny disk in the center, inside of Jupiter's orbit. The planets are far from the Sun, travel huge distances in space, and take a long time to do so. Pluto takes almost years to go around the Sun completely and travels almost 23 billion miles to do so!

But, once again, things are complicated by the fact that Venus has an unusual rotation period. In fact, Venus takes Earth days to rotate once on its axis — the slowest rotation of any planet — and its rotation is retrograde to its orbital path.

Combined with its orbital period, this means that a single solar day on Venus the time between one sunup to the next is Earth days. So basically, a single year on Venus is lasts 1. Cytherean days. Again, this would make for some confusing time-cycles for any humans trying to make a go of it on Venus!

Add to that its unusual day-night cycle, variations are very slight. Comparatively speaking, a year on Earth is pretty predictable, which is probably one of the reasons why life is able to thrive here. In short, our planet takes But because our axis is tilted, there is considerable variation in the seasons during the course of a year. As a result, between the summer and winter, the length of days and nights, temperatures, and seasons will go through significant changes.

In the southern hemisphere the situation is exactly reversed, with the South Pole experiencing a midnight sun, a day of 24 hours, again reversing with the South Pole. Every six months, the order of this is reversed. Mars has one of the highest eccentricities of any planet in the Solar System, ranging from ,, km at perihelion and ,, km at aphelion.
