Which Planet Has Longest Day And Shortest Year?

So, Venus has the longest day of any planet in our solar system.

It completes one rotation every 243 Earth days.

Its day lasts longer than its orbit.

It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.

Which planet has the shortest year in the solar system?

The Planet with the Shortest Year: Mercury; a year on Mercury takes only 88 Earth days. The Planet with the Longest Day: Venus; a day on Venus takes 243 Earth days.

Which planet has longest year?

A Year On Neptune: 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).

What planet has the shortest day?

The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.

How long is a day and year on each planet?

On what planet is a year shorter than a day?

So, Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days. Its day lasts longer than its orbit. It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.

How do you age slower in space?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

Which planet has days longer than 24 hours?

On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours.

Which planet has more than 60 moons?

Jupiter’s moons. Each of the gas giant planets can be thought of as its own mini version of the Solar System. Each planet has a large system of moons which are in orbit around it. Jupiter has more than 60 moons, Saturn has more than 30, Uranus more than 20, and Neptune more than 10.

What planet is the smallest?

If we put our planets in ‘size order’ they would be listed as the following, from large to small: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Since we lost Pluto as an official planet, it appears that Mercury is now considered the smallest planet in the solar system.

What planet has a similar day as Earth?

In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways. A Martian day is just over 24 hours, and its rotation axis is tilted by about the same amount as Earth’s.

Which planet would float in water?


On which planet would you weigh the most?

Since Pluto was demoted to a dwarf planet, Mars became the planet where you would weigh the least. Jupiter is the largest planet in our Solar System with the most mass. Because of Jupiter’s mass, you would weigh more on that planet than on any other one in our Solar System.

How old would I be on Pluto?

Now what you do is divide your age in Earth years by the length of the planet’s year in Earth years to get you age in that planets years. For example, if I were 21 Earth years old, I would be 21/0.241 = 87 Mercury years old and 21/248.6 = 0.08 Pluto years old.

Does time go slower in space?

As you move faster in space, time goes slower. As seen in the movie, “Interstellar,” Earth’s surface has a higher gravity than the Martian surface, so on Mars you will experience your seconds slightly faster than people on Earth.

Do you age in space?

These changes resemble aging in people age on Earth, but happen more quickly. That makes spaceflight an opportunity to study – and perhaps lessen – the effects of aging. “There is something about being in space for an extended period of time, more than several weeks,” said Roberts.

How long is a day on Pluto?

Pluto rotates much more slowly than Earth so a day on Pluto is much longer than a day on Earth. A day on Pluto is 6.4 Earth days or 153.3 hours long.

How long is day on Uranus?

A planet’s day is the time it takes the planet to rotate or spin once on its axis. Uranus rotates faster than Earth so a day on Uranus is shorter than a day on Earth. A day on Uranus is 17.24 Earth hours while a day on Earth is 23.934 hours.

Do astronauts get paid?

Currently a GS-11 starts at $66,026 per year and a GS-14 can earn up to $144,566 per year. Military Astronaut Candidates are detailed to the Johnson Space Center and remain in an active duty status for pay, benefits, leave, and other similar military matters.

Do astronauts age faster?

That increased radiation can affect their cells and increase their risks for a variety of cancers. That is aging. An astronaut, by being in microgravity, experiences bone loss. While in space, astronauts lose up to 1.5% of their bone mass for each month spent in space.

Why is time slower near a black hole?

As you get closer to a black hole, the flow of time slows down, compared to flow of time far from the hole. (According to Einstein’s theory, any massive body, including the Earth, produces this effect. Near a black hole, the slowing of time is extreme.

How many planets have no moon?

The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them. Figuring out why is one question keeping astronomers busy as they study the Solar System.

Which planet has more suns?

Luke Skywalker’s home planet, Tatooine, in the Star Wars saga, was a strange world with two suns in the sky, but astronomers have now found a planet in an even more exotic system, where an observer would either experience constant daylight or enjoy triple sunrises and sunsets each day, depending on the seasons, which

How long is a day in Saturn?

A planet’s day is the time it takes the planet to rotate or spin once on its axis. Saturn rotates faster than Earth so a day on Saturn is shorter than a day on Earth. A day on Saturn is 10.656 hours long while a day on Earth is 23.934 hours long.
