# How Long Does It Take To Travel Around The Sun?

How long does it take the Earth to complete its orbit around the Sun? Obviously, the answer is one year, or 365.25 days, as the question states. It is not quite so straightforward, though, because there are several different meanings of the term ″year.″

The Earth completes one complete rotation around the sun in 365 days, 5 hours, 59 minutes, and 16 seconds. A year is the amount of time it takes for a planet to complete one full round around the sun.

## How many days to the Sun at the speed of sound?

When traveling at 767 miles per hour, the speed of sound is equal to the distance between Earth and the Sun (92,960,000 miles). At the speed of sound, this will provide you with the number of hours till the Sun rises. The number of days to the Sun is calculated by dividing 121,199,478 by 24. The correct answer is 5,049.98 days till the Sun rises.

## Why does light take so long to reach the Sun?

The fundamental premise of special relativity is that the velocity of light is the same for any inertial observer regardless of location. The fact that the distance between the Sun and the Earth is not zero, and that light travels at the same speed for all observers, ensures that it will always take some time to reach its destination.

## How far away is the Sun from Earth?

The sun, on the other hand, is around 150 million kilometers distant (the exact distance depends on the time of year). Because we know that light travels at a speed of 300,000 kilometers per second, the computation is straightforward.
