Solar System Light Years Distance

Source various articles on wikipedia. At those distances it would take you 19 million years to complete the journey to the edge of the solar system.

A light year is the distance light travels in one earth year.

Solar system light years distance. We complete one rotation of the galaxy is 230 million years. For most space objects we use light years to describe their distance. That distance is nearly 6 trillion miles but a light year conveys time more than it does actual distance.

Because the galaxy is so huge astronomers had to come up with a unit of measurement able to convey such incredible distance. One light year is about 6 trillion miles 9 trillion km. An au is equal to 149600000 km.

More p recisely one light year is equal to 9500000000000 kilometers. Why would you want such a big unit. When we use powerful telescopes to look at distant objects in space we are actually looking back in time.

Our solar system is located about 27000 light years away from the galactic center in the milky way. The diameter of the solar system is approximately 7500000000 miles and light travels 5865696000000 miles in a year so the diameter of the solar system is about 00013 light years. Back to our car analogy for a second.

The result was the light year which covers the distance that light travels in one year. The moon the closest solar system body to us is about 400000 km away from the earth which means it takes about 2 seconds for radio signal from earth to reach the moon and travel back. It is around 93 au astronomical units average distance between earth and sun.

A light year is a unit of distance. Looking back in time. That is a 6 with 12 zeros behind it.

Which means that the solar system is 12 hours and 535 minutes across which is around 00015 light year. So in one year it can travel about 10 trillion km. It is the distance that light can travel in one year.

Even nasas new horizons spacecraft the fastest object ever launched from earth would need 37000 years to make the trip. And 1 au8317 light minutes. The solar system is located in the orion arm 26000 light years from the center of the milky way galaxy.

Light moves at a velocity of about 300000 kilometers km each second. It takes 8 minutes for light to travel from the sun to the earthtraveling at the speed of light of course. You could hear this delay in communications between the apollo astronauts and the ground control.
