The planet with the slowest rotation (not orbital speed) is Venus, which has a rotation period of 243 Earth days. This works out to a tangential speed at the equator of only 1.8 meters per second (4.1 mph, 6.5 km/h).
Which planet has the slowest orbital speed?
If Pluto had maintained its planet status, it would have the slowest orbital speed at just 10,438 miles per hour. Instead, Neptune again wins with an orbital speed of 12,148 miles per hour. Compared to Earth’s 66,621 miles per hour, Neptune is practically sluggish.
Which planets move the most slowly?
Their speeds vary, but Mercury is the fastest, followed by Venus, Mars, Jupiter, and then Saturn, the slowest. This motion is called direct motion.
Is Saturn the slowest planet to orbit the sun?
As the farthest of the planets known to ancient observers, Saturn also was noted to be the slowest-moving. At a distance from the Sun that is 9.5 times as far as Earth’s, Saturn takes approximately 29.5 Earth years to make one solar revolution.
Which planet revolves slowly around the sun?
Out of 8 planets Neptune is moving at the lowest speed around Sun. Its orbital speed is around 5.43 km/s.
What is the fastest thing in the universe?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
What is the fastest planet?
Mercury is the smallest and fastest planet in the solar system.
Which planet spins the second fastest?
The second fastest spinning planet is Saturn, which is also a gaseous planet, and it spins at a speed of 22,000 miles per hour while the third fastest planet is Uranus with a speed of 9,192.5 miles per hour.
Which planet moves more slowly across the sky?
Which planet moves more slowly across the sky Saturn or Mars? Saturn moves more slowly across the sky than Mars.
Is Saturn hot or cold?
With an average temperature of minus 288 degrees Fahrenheit (minus 178 degrees Celsius), Saturn is a pretty cool planet. Although there are some small differences as one travels from the equator to the poles, much of Saturn’s temperature variation is horizontal.
What color is the Jupiter?
: The color of Jupiter is yellow or yellowish orange.
Which planet has the longest year?
Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).

Does Jupiter have rings?
Jupiter is surrounded by dozens of moons. Jupiter also has several rings, but unlike the famous rings of Saturn, Jupiter’s rings are very faint and made of dust, not ice.
Which two planets are called ice giants?
Given their large distances from the Sun, Uranus and Neptune are much colder and have a higher abundance of atmospheric water and other ice-forming molecules, earning them the nickname “ice giants.” Ice giants are mostly water, probably in the form of a supercritical fluid; the visible clouds likely consist of ice …
