What is the longest orbital period?
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).
Which region has the shortest orbital period?
Jupiter, which takes nearly 12 years to travel around the Sun, has the shortest orbital period of any large planet (more massive than Earth) in the solar system. Even the closest planet to the Sun, Mercury, requires 88 days to complete an orbit.
What is the orbital period of Earth in Earth years?
365 days
Which planet has the fastest orbital period?
Mercury
Which planet has the slowest orbital velocity?
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.
What is the slowest planet?
Venus
What planet is closest to the sun?
What is the fastest planet?
Which planet rotates the slowest around the sun?
Venusian
Which planet is most like Earth?
Kepler-452b
Which planet spins the second fastest?
Saturn
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.
What determines how fast a planet spins?
The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon).
What planet revolves quickly but rotates slowly?
Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow.
Why does Uranus spin backwards?
Uranus was likely hit by a very large planetoid early in its history, causing it to rotate “on its side,” 90 degrees away from its orbital motion. Venus rotates backwards compared to the other planets, also likely due to an early asteroid hit which disturbed its original rotation.
Is there life on Venus?
Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.
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.
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.
Which planet takes 84 years to orbit the sun?
Uranus
Which planet takes 29 years to orbit the sun?
Saturn takes about 10.7 hours (no one knows precisely) to rotate on its axis once—a Saturn “day”—and 29 Earth years to orbit the sun.
How old would I be on Pluto?
Poor, ponderous, and distant Pluto takes a whopping 248 years for one revolution….The Days (And Years) Of Our Lives.
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Saturn | 0.45 days | 29.46 years |
| Uranus | 0.72 days | 84.01 years |
| Neptune | 0.67 days | 164.79 years |
| Pluto | 6.39 days | 248.59 years |
How old am I on Mars?
4.603 billion years
What planet takes 11 years to orbit the sun?
The orbits of Venus, Earth and Jupiter may explain the sun’s regular 11-year cycle, a new study suggests.
How long is 1 day on Neptune?
0d 16h 6m
How old is Venus the planet?

How old is Uranus?
Who named Uranus?
Johann Elert Bode
Who discovered Uranus?
William Herschel
Is Uranus named George?
English astronomer William Herschel discovered the planet in 1781 during a telescopic survey of the zodiac. He promptly named it the Georgium Sidus (the Georgian Planet) in honor of his patron, King George III. Later, to the everlasting delight of schoolchildren, George was re-named Uranus, the Greek god of the sky.
Who named Mars?
Mars is named for the ancient Roman god of war. The Greeks called the planet Ares (pronounced Air-EEZ). The Romans and Greeks associated the planet with war because its color resembles the color of blood. Mars has two small moons.
