86,400 seconds = 1 day
365.24 days = 1 year
Two light years = (186,282) x (86,400) x (365.24) x (2) = 11,757,000,000,000 miles (rounded)

from the nearest star, and almost 14 billion years from the farthest stars that astronomers
have been able to detect up until now.

Regardless, the Milky Way Galaxy is approximately 120,000 light years in diameter, and therefore, it would take 120,000 years to cross it IF YOU WERE TRAVELING AT THE SPEED OF LIGHT. At half the speed of light, it would take 240,000 years, at one-fourth the speed of light, it would take 480,000 years, etc.

The closest star after that is Proxima Centauri which is 4 light years away. It is one of three stars orbiting each other in the Alpha Centauri system.
The furthest star on the other side of the Milky Way galaxy would be 100,000 light years away since that is how wide the galaxy is estimated to be.
Since we don't know the size of the universe, the furthest star would be an almost infinite distance away.

∙ 13y agoA light year is a unit of distance, not time. It is the distance that light will travel in 1 year, and is commonly used to express the distance between solar systems and galaxies.
1 light year = 9.4605 x 1015 meters

∙ 13y agoThere's no way to answer that question until we're sure that we have observed
every star, and have measured the distance to every star that we've observed.
Since there are somewhere between 200 and 400 billion stars in our galaxy alone,
and billions of other galaxies, that day is still a long way off.
But we can state a figure that comes straight out a very large "ball park" :
The farthest galaxies observed up to the present time are roughly 14 billion light years
from us. So to the same level of precision, we can also say that the farthest stars
observed up to the present time are also roughly 14 billion light years away.

∙ 15y agoThe Sun is our nearest star. It is 92.9 million miles (149.6 million km) away from Earth. Stars are massive nuclear reactors, generating energy in their cores. It is the heat and light from the sun that makes life on Earth possible. The huge gravity pull of the sun keeps the planets of our solar system orbiting around it. If that was not what you meant, the next nearest star is Proxima Centauri, a red dwarf star in the 3-star system of Alpha Centauri. 4.22 light years away. This star is very small and faint compared with the sun and so it may seem like it is untypical. However, the overwhelming majority of stars appear to be small and faint red dwarfs, so Proxima Centauri is actually a very typical star.

In bigger numbers, that equates to:
- 9.4605284 × 1013 kilometres
- 5.87849981 × 1013 miles
- 632,396.717 AU

Why scientists use light years to measure distance in space in stead of kilometers?
It is far more convenient to express space distance in light years instead of kilometers. 1 light year = 9.4605 x 10^12 km 1 light year = 5.8745 x 10^12 miles

How long is a light century?
It would depend on how fast you are moving. It would take 20 million years IF you could move at the speed of light (which you cannot). The fastest man has ever travelled is 24,000 miles per hour (Apollo moon flight) Light moves at 671,000,000 MPH, or 27,958.3 times faster than man has ever moved. The trip would be in the billions of years.

Define light year and explain its value in astronomy?
A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers. In popular astronomy, distances to stars or galaxies are often stated in light-years; although astronomers often prefer another measure, the parsec, equivalent to about 3.26 light-years.A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers.

What is 100.000 light years in miles?
You can calculate a light year on a claculator. Take the speed of light, 186,282 miles per second, then multiply by 3600 to get miles per hour, then multiply by 24 to get miles per day, then by 365.2425 to get miles per year. That is one light-year in miles.Then multiply by 60,000 to find the answer, which is 3.5271x1017 miles, or 352,710,000,000,000,000 miles.
How many miles are in 4000 light years?
(4.06 X 10-8) x (5.8787 x 1012) = 238,680 miles(rounded)That number looks strangely similar to the moon's average distance from earth.Could that be what the questioner was getting at ???
Explain what a light year is and why great distances between stars are given in light years and not miles?
A light-year is the distance light travels in a year. Distances between stars are given in light-years because it is easier to visualize "10 light-years" (the distance travelled by light in 10 years), than "9.5 x 1213 kilometers".
How far is mars from the sun in light years?
