How many years is 5000 light years?

Answer 1

Light travels at 186,282.397 miles per second (299,792,458 Kilometers / second).

There are 31,556,736 seconds in a year. Therefore light will travel 5,878,464,423,576.192 (6 trillion) miles per year.

So 3,000 Ly = 17,635,393,270,728,576 miles (28,381,414,355,691,264,000 kilometers)

or 17.6 quadrillion Miles (28.4 quintrillion kilometers)

Answer 2

It would all depend on what speed you travel at.

Forgetting acceleration and deceleration, which is important the closer you get to the speed of light.

At the speed of light ~ 300 years.

At 500,000 mph ~ 402,370 years

At 55mph - 582,991,715,702 years - about 44 times longer than the Universe has existed.

Answer 3

Light travels at 300,000 km per second, or 186,000 miles per second. Multiply those numbers together.

The answer is 93,000,000 miles from the Sun to the Earth. This distance is defined as one "astronomical unit", or AU.

Answer 4

Quite a few, too many to use as a handy measure. Just one light-year is almost six sextillion miles. (You've heard about the three-trillion-dollar budget? Figure, quadrillion, quintillion, sextillion.....)

Answer 5

The light from a star 5000 light-years away will reach the Earth 5000 years after the light leaves the star.

But the star itself will never reach the Earth. Stars do not, in general, collide with each other - or at least, do not do so very often.

Answer 6

Are you sure you can cope with the numbers?

2,939,249,910,000,000,000,000,000 miles.

That's

122,468,746,250,000,000,000 times around the Equator of Earth

or

15,802,418,870,967,741 times to the Sun and back.

Answer 7

"Light year" is a distance ... it's the distance light travels in one year, or about 5,878,700,000,000 miles.

"Year" is a period of time ... it's the time elapsed while the earth makes one complete revolution

around the sun.

As you can see, these two units are completely different, although they do share the same word.

They have different physical 'dimensions', they're used to measure completely different quantities,

and neither of them can be converted to the other one.

Answer 8

A light-year is not a unit of time. It is a unit of distance - the distance light travels in a year, about 9.5 x 1012 km.

Answer 9

If the source is 300 light years away from you, then you see light that left the source 300 years ago.

It may not be there any more. You'll know in 300 years.

Answer 10

5000 years. By definition, a light year is the distance a beam of light can travel in one year.
