(Grades 5-8) series. Mercury is the smallest and fastest planet in the solar system. It is also the closest planet to the sun. It is named after the Roman messenger god Mercury, the fastest Roman god.
What is the slowest planet?
Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe.
What planets move the fastest?
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. This means that Jupiter has the shortest days of all the planets in the Solar System.
Which planet is fastest around the sun?
Answer: Mercury is the winner at an orbital speed of about 47.87 km/s (107,082 miles per hour), which is a period of about 87.97 Earth days.
Can you touch Jupiter?
First things first, Jupiter’s atmosphere has no oxygen. … You’ll quickly hit the denser atmosphere below, which will hit you like a wall. It won’t be enough to stop you, though. After about 3 minutes you’ll reach the cloud tops 155 miles down.
Which planet rotates the slowest around the sun?
Venus is the slowest – it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. A Venusian sidereal day thus lasts more than a Venusian year (243 versus 224.7 Earth days).
Which planet is most like Earth?
Kepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 pc) from Earth in the constellation Cygnus.
Which planet rotates faster than Earth?
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.
At what point does the planet move slowest?
A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Why Jupiter spins so fast?
When Jupiter formed, it accreted its atmosphere (over 95% of the planet’s total mass!) from the hydrogen and helium gas in the protoplanetary disk surrounding our Sun. As Jupiter ate up this gas mass, it must have begun to spin faster as it also ate up the gas’s angular momentum.
What is the coldest inner planet?
With a temperature of -357 degrees Fahrenheit, Uranus is the coldest planet in the solar system.
Which planet has the most moons?

Can you walk in Jupiter?
Space scientists don’t really know if Jupiter has a hot, rocky core or if it is just gas all the way down. Therefore, it’s essentially impossible for any person to set foot on any ‘surface’ of Jupiter.
Does it rain diamonds on Jupiter?
Thus, we can say that it literally rains diamonds on Saturn and Jupiter. But these diamonds do not stay in solid form for too long as when they move farther into the depths of the planets, the pressure and temperature there are strong enough to melt them into liquid, creating liquid diamonds.
Why is Jupiter so special?
After the Sun, the Moon and Venus, Jupiter is the brightest and is one of five planets which can be seen by naked eye from Earth. Jupiter is the only planet that has a center of mass with the Sun that lies outside the volume of the Sun, though by only 7% of the Sun’s radius. Jupiter has a very unique cloud layer.
