Therefore a light year is exactly 94607304725808 kilometers. For general reference there are 63000 astronomical units in one light-year and 63000 inches 160000 cm in one mile 16 km.

To travel one lightyear 95 trillion km just to mention two extremes.
How long is. light year. Light travels a whopping 9460528000000 km in a year equivalent to 5878499562555 miles. Light moves at a velocity of about 300000 kilometers km each second. A light year is a measurement of distance.
BOOK A Briefer History of Time by Stephen Hawking. How far is 40 light-years. That is a 6 with 12 zeros behind it.
A light year is the distance that light travels in one year. In one year 36525 days that is equivalent to 5869713600000 miles. The galaxy is about 100000 light-years across and the Earth is about 28000 light-years from its center.
If you are wondering there are just about 31500000 seconds in a year and if you multiply this by 186000 the distance that light travels each second you get 59 trillion miles 94 trillion. The resulting distance is almost 6 trillion 6000000000000 miles. 101 rows Following is a table shows how far is a light year in miles kilometers inches feet and.
At one centimeter per second 001 m s 1 the trip takes 30 billion years. A light year is a measure of distance equal to how far light travels in one Earth year. There are about 8766 hours per year so light travels 59 trillion miles per year.
A light-year is the distance light travels in one Earth year. Because distances across the universe are so large astronomers use light years. Define the light year.
It is the distance that light can travel in one year. Thus we have the light year and the parsec. Httpsamznto2GSh2yW DIVE INFollow me on Twitter.
The speed of light is 186000 miles per second or 671 million miles per hour. Looking Back in Time. Determining how long it takes to travel one light year depends in part on the speed of the observer.
It would take you three years to get 21 nov 201728 aug 2017 a year dis. Light travels super fast at 186282 miles per second or about 670 million miles per hour. Those are really large numbers.
This distance is measured by how far light can travel in a year. At lightspeed c 299 792 458 m s 1 the trip takes exactly one year. There is also the astronomical unit au which is the distance from the sun to the Earth.
Light travels at approximately 186000 miles per second. This many seconds is an even larger number than the of miles light goes in one second. So in one year it can travel about 10 trillion km.
A mile is a unit of distance equal to 5280 feet or exactly 1609344 kilometers. A light-year is defined as the distance that light can travel in 1 year. For any speed in between these extremes Do the math.
One light-year is about 6 trillion miles 9 trillion km. To obtain an idea of the size of a light-year take the circumference of the earth 24900 miles lay it out in a straight line multiply the length of the line by 75 the corresponding distance is one light-second then place 316 million similar lines end to end. In February 2017 astronomers detected seven Earth-sized planets orbiting a single star 40 light-years away from Earth.
This wonderful coincidence enables us to bring the light-year. If the observer is traveling at the speed of light then by definition it takes one year. We can calculate this by multiplying the speed of light by 1 year or 31557107 seconds to find the distance.
If you imagine the galaxy as a city. More p recisely one light-year is equal to 9500000000000 kilometers. The year used by the International Astronomical Union is 36525 days.
Parsecs are probably easier for physicists to use a parsec is 33 light years but for us regular folk light years work well enough. An astronomical unit is roughly 93 million miles or 150 million km.
