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).
How long is a year on each planet?
The Days (And Years) Of Our Lives
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Earth | 0.99 days | 365.26 days |
| Mars | 1.03 days | 1.88 years |
| Jupiter | 0.41 days | 11.86 years |
| Saturn | 0.45 days | 29.46 years |
Which two planets have the longest years?
Venus, which is roughly 38,200,000 km from Earth at its closest approach. The Planet with the Longest Year: Pluto; a year on Pluto takes 248.5 Earth years.
Which planet has shortest year?
Mercury is an extreme planet in several respects. Because of its nearness to the Sun—its average orbital distance is 58 million km (36 million miles)—it has the shortest year (a revolution period of 88 days) and receives the most intense solar radiation of all the planets.
What is my age on Mars?
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Is there a 9 planet?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
What is the smoothest planet?
Jupiter’s large icy moon Europa has the smoothest surface of any solid body in the Solar System. The only prominent relief on its surface are ridges a few hundred metres in height.
What planet is the least dense?
Jupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense. It’s less dense than water, which has led many people to postulate that it would float.
What planet takes 7 years to get to?
FAQ – Spacecraft
| Spacecraft | Target | Time |
|---|---|---|
| Messenger | Mercury | 6.5 years |
| Cassini | Saturn | 7 years |
| Voyager 1 & 2 | Jupiter; Saturn; Uranus; Neptune | 13,23 months; 3,4 years; 8.5 years; 12 years |
| New Horizons | Pluto | 9.5 years |
What planet has no seasons?
As the closest planet to the sun, Mercury’s climate varies significantly throughout its year, which equates to 88 Earth days. Mercury is also the only planet in our solar system without any tilt, so technically lacks seasons.
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
Does Pluto age slower?
No. The time-dilation effect of Einstein’s relativity has nothing to do with space. It has to do with speed. The faster you’re moving, the slower time goes for you.
How old is a 13 year old in days?
How many days old are you? At 13 years old, you’ll be 4745 days old!
Do you age faster on Mars?
Mass of Mars is lesser than that of Earth which means the time passes faster there relative to Earth. Hence, you would age faster on Mars relative to Earth.
