Those are all measures of length.
Yes, astronomers use light-years to measure the distance between stars in space. A light-year is the distance that light travels in one year, which is about 9.46 trillion kilometers or 5.88 trillion miles. This unit of measurement is more practical given the vast distances in space.
Betelgeuse is 640 light-years away from the Earth. 1 light-year is the distance traveled by light in 1 year. speed of light = 3 x 108 meters per second So, 1 ly = 3 x 108 x 365 x 24 x 60 x 60 = 9.46 x 1015 meters 640 light-years = 640 x 9.46 x 1015 = 6.05 x 1018 meters 1 meter = 0.621 x 10-3 miles 640 light-years = 6.05 x 1018 x 0.621 x 10-3 = 3.76 x 1015 miles That is 3,760,000,000,000,000 miles.
Light years
The distance to stars is typically measured in light-years, which is the distance light travels in one year. Light-years are used because the distances to stars are vast and measuring in kilometers or miles would be impractical. For closer stars, distances can sometimes be measured in parsecs, which is another unit of distance based on trigonometric parallax.
885 million miles = 0.000150548614 light years.
4.4 what? Microns? Light years? miles?
It's measured in light-years (or parsecs) which is trillions of miles.
It's measured in light-years (or parsecs) which is trillions of miles.
A distance of 40 light years is approximately 377 trillion kilometers or 235 trillion miles away.
Stars are not measured in light years. The distance between them is.
Inches? Feet? Planck Lengths? Meters? Light Years? Parsecs?
1 ligt year equals 5,878,625,373,184 miles or 9,460,730,472,581 km
Not really. A light year is a measure of distance. It is the distance light can travel in one earth year, about 6 trillion miles
Light years. This is defined as the distance that light will travel in one year. It's equivalent to around 10 trillion km or 6 trillion miles.
They are measured in light years. Galaxies are often 100,000 light years across or more.
The term that refers to how far apart two objects or places are located is distance. Distance can be measured in various units such as meters, kilometers, miles, or light-years.
