How many miles are there in 10 light years?

Answer 1

The Sun is at a distance of 8 light-minutes; about 150 million kilometers.

The next known star (apart from our Sun) is Proxima Centauri, at a distance of 4.2 light-years.

Answer 2

Speed of light = 186,282 miles per second

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)

Answer 3

Many years. If you don't count the sun, it takes light about 4.4 years to travel to earth

from the nearest star, and almost 14 billion years from the farthest stars that astronomers

have been able to detect up until now.

Answer 4

Lightyears is not a measure of time, but of distance. 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.

Answer 5

The brightest and closest star is of course our sun which is 1 AU(150 million Km or 93 million Miles) away from Earth or 8 light minutes.

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.

Answer 6

A 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

Answer 7

There'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.

Answer 8

The 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.

Answer 9

Proxima Centauri is the closest star after our sun. Our sun is around 93 million miles from earth, Proxima Centauri is 4.243 light years, which is around 24,940,000,000,000 miles or 24.94 trillion miles.

Answer 10

A star that is 10 light years away is well 10 light years away.

In bigger numbers, that equates to:

• 9.4605284 × 1013 kilometres
• 5.87849981 × 1013 miles
• 632,396.717 AU
