what is the distance of the sun from the earth in light years?

Almost every day we look at sun rise and set, except when the sky is clouded. How far does the Sun from the Earth? Maybe it makes you wonder huh. The most concise answer is 1 AU (Astronomical Unit). and, but it is useless yeah? The other answer is 8 "light minutes". However, you must still confused, 8 light minutes is equal to how many kilometers?.

The unit "light year" is usually used to determine the distance between celestial objects in space: 1 light year is approximately equal to 300,000 x 365 x 24 x 60 x 60 kilometers. This calculation is related to the speed of light propagating in space, which is approximately 300,000 kilometers per second. So, in 8 minutes, the light will propagate as far as 300,000 x 8 x 60 kilometers, which is equal to 144,000,000 kilometers. This calculation is not exactly true, but that's roughly the distance of the Sun from the Earth. so Far.

Later, precisely in the year 1653, an astronomer name Christiaan Huygens calculate the distance of the Sun from the Earth more accurately, using a triangulation method involving the Sun, Earth and Venus. Huygens calculation results corrected again by Giovanni Cassini in 1672, using the parallax method, which includes the calculation of the angle more thoroughly.

Distance of the Sun from the Earth, which is then expressed as 1 AU, the current set equal to 149597870.7 kilometers. With speed aircraft 10,000 kilometers per hour (~ 10 times faster than a regular plane), it took 20 months to travel so far!.
