# Question: How Long Is One Revolution Of The Sun?

## Which two 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)..

## How long does it take around the sun?

365 daysWell, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time.

## How long is a day on the sun?

But even this solution to the question depends on where one is standing on the Sun as different parts of the Sun rotate at different speeds. At the equator, it would take approximately 24.5 Earth days while at the poles about 34 Earth days.

## How long does it take the Sun to complete one orbit?

about 230 million yearsAnswer: Yes, the Sun – in fact, our whole solar system – orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way!

## What planet has the longest year?

Kepler-421b, a newly discovered planet that’s outside of our solar system, takes the cake for exoplanet with the longest year. It takes 704 Earth days, or about 2 Earth years, for the exoplanet to make one revolution around its star.

## What planet has the shortest year?

MercuryMercury 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.

## How long is 1 day in space?

90 minutesThere aren’t really ‘days’ in space unless you are on another planet. However, a good analog on the International Space Station would be the time it takes to make one complete orbit. An ISS day is 90 minutes, which means astronauts get to see about 16 “sunsets” per 24 hour period.

## 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. The tidal forces which cause Io’s intense volcanic activity also affect Europa.

## How long is a revolution of the sun?

about 225-250 million yearsBottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy’s center. This length of time is called a cosmic year.

## 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.
