A light year is the distance light travels in one year. About 6 trillion miles.
--
Light years are used because it would be plain crazy to use miles. It's a lot easier to comprehend it when someone says "The Centauri stars are roughly 4 light years away" as opposed to saying "The Centauri stars are about 24 trillion miles away."
What else can I help you with?
What can the distances to nearby stars be measured by?
Light years
What can the distances of nearby stars be measured by?
parsecs or light years
What units are distances to stars measured in and why?
Usually such distances are measured either in light-years, or in parsecs.
Explain why stars distances is measured in light years?
because the stars are very far away so the astronomers use light years
The unit to measure distances between stars is in?
Light years or parsecs
What are the units called that measure distances to stars?
They measure them in light-years.
What unit would you use to measure the distances from stars?
To measure the distance of stars you have to measure by light years.
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".
What is the unit of measurement of the distances of the stars from the earth?
Light Year is unit for all astronomic distances
Distances from earth to a dwarf stars?
the nearest one is 90 million light years away
What unit of distance do astronomers use to measure distances to stars?
Usually light-years, or parsecs.
What is the distance between vega deneb and altair?
Vega, Deneb, and Altair form the vertices of the Summer Triangle in the night sky. The approximate distances from Earth to these stars are about 25 light-years for Vega, 1,425 light-years for Deneb, and 16.7 light-years for Altair. While these distances vary, the stars are not physically close to each other in space; they are separated by vast distances, with Deneb being the farthest away. The actual distances between the stars in light-years can be calculated using their respective coordinates, but they are all situated in different regions of our galaxy.
