Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is.
Venus, our closest planetary neighbor, has the slowest rotational period of any world in our solar system—and according to data recently gathered by the European Space Agency's Venus Express orbiter, it's getting slower.
This animation illustrates the difference in the rotational period between the Earth and Jupiter. Earth rotates once in 24 hours; whereas, Jupiter rotates more quickly, taking only about 10 hours. This means that Jupiter rotates about 2 1/2 times faster than the Earth.
Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation.
The time dilation on that planet—one hour equals 7 Earth years—seems extreme. To get that, you'd apparently need to be at the event horizon of a black hole. Yes. You can calculate where you must be to have that level of time dilation, and it's extreme.
Answer and Explanation: Jupiter is the fastest spinning planet for the same reason that it is the largest planet: it has the gravity to attract the most mass as it travels through space.
You will age slowest on Mercury, Venus and Jupiter as they are slower than Earth. You will age a couple of minutes faster on Mars as it is less massive and has less gravity than Earth.
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
A day on Venus is longer than a year
That's 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.
Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.
As far as we know, there aren't any planets out there that don't rotate at all. The processes that form planets and other celestial bodies naturally result in rotation, meaning that all worlds spin from the outset.
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons.
So where does that redness come from? Well, a lot of rocks on Mars are full of iron, and when they're exposed to the great outdoors, they 'oxidize' and turn reddish - the same way an old bike left out in the yard gets all rusty.
Uranus' axis is so tilted, it actually looks like the planet is rotating on its side. How did this all happen? One theory is that a body the size of our Earth collided with Uranus a long time ago, radically throwing off its rotation. And Uranus will keep doing the side shuffle like nobody's watching.
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.
But now the fight over which planet has the most moons in its orbit has swung decisively in Saturn's favor. This month, the International Astronomical Union is set to recognize 62 additional moons of Saturn based on a batch of objects discovered by astronomers.
Although the moon is our only permanent natural satellite, astronomers have discovered many other near-Earth objects that could be considered honorary 'mini' moons.
Time moves more slowly in space than it does on the earth. This is a result of gravity and relative velocity. Relative velocity is the speed at which one is moving in relation to another object.
Saturn is known as the "Grandfather" of all the planets and is one of the main causes of premature ageing. Saturn's negative impacts can cause hair loss, dry skin, wrinkles, and make the native appear older than he is.
3. To find your age on the outer planets (Jupiter, Saturn, Uranus, Neptune, and Pluto), divide your age in Earth years by the approximate length of the planet's year in Earth years. This is your “new” age. For example, a 20 year old on Earth would only be 1.7 years old on Jupiter because 20 / 12 = 1.7.
Jupiter is 300 times heavier than Earth, which makes its gravitational force extremely strong. Due to this your jump on Jupiter, made with similar force you applied on Earth, shrinks to 0.17 metres.
Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it's the closest planet to the sun, it goes around the Sun in just 88 Earth days.
Neptune is our solar system's windiest world. Despite its great distance and low energy input from the Sun, Neptune's winds can be three times stronger than Jupiter's and nine times stronger than Earth's.
