How may miles in an astronomical unit?

Answer 1

You divide the number of miles by six trillion (6 x 1012).

You divide the number of miles by six trillion (6 x 1012).

You divide the number of miles by six trillion (6 x 1012).

You divide the number of miles by six trillion (6 x 1012).

Answer 2

One astronomical unit (AU) is approximately 93 million miles. This is the average distance from the Earth to the Sun, commonly used as a unit of measurement in astronomy for distances within our solar system.

Answer 3

Light-year: the distance light travels in a year, about 9.5 x 1012 km.

Astronomical unit: the distance from Sun to Earth, about 150 million km. For comparison, it takes light a little over 8 minutes to traves that distance; a light-year has about 60,000 astronomical units.

Answer 4

Astronomical unit is the distance from Sun to Earth - this is about 8 light-minutes, the time it takes for light to travel 8 minutes. Therefore, the AU is much less than a light-year.

Answer 5

One light year is the distance that light travels in one year. One AU is the distance from the Sun to the Earth, approximately 8.3 light-MINUTES. A light-year is about 62,000 times larger than an AU.

Answer 6

The "light year" is a unit of distance defined as the distance that light travels

through vacuum in one year.

The "astronomical unit" is a unit of distance defined in terms of the Earth's

distance from the Sun.

One light-year is equivalent to roughly 63 thousandastronomical units.

Answer 7

Generally, they aren't - the two terms are too clumsy to try and use together. The "Astronomical Unit" is the distance from the sun to the earth, or about 8 light minutes. You can see the clumsiness in using it along with light years. A.U. is really only useful with the context of our solar system. Light year is useful in any context of interstellar space.

Answer 8

They are very similar because they are both units of spatial measurement (they measure distances). They are alike because they are both used to measure very long distances in space.

1 Astronomical Unit = distance from Earth to Sun (approx. 93 million miles)

1 Light Year = the distance light rays (photons) travel in one Earth year (approx. 6 trillion miles)

Answer 9

They are both measurements of distance. A lightyear is the distance light travels in one year, which at 186,000 miles per second, is around 5.7 trillion miles. An astronomical unit is the average distance from the Earth to the Sun, roughly 93 million miles.

Answer 10

The "Astronomical Unit" is defined as the mean distance between the earth and sun.

It's approximately equal to 93 million earth miles, which is quite a difference
