What do variable stars help astronomers measure?
Distance.
How do astronomers measure distance to the stars?
With a long measuring tape.
How do astronomers measure distances to stars including the parallax method?
They use the banana method
What are the distances to stars measured in?
Astronomers typically measure distances in parsecs. One parsec is the distance of a hypothetical star having a parallax of 1 second of arc; it's about 3.2 light years.
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
What unit would you use to measure the distances from stars?
To measure the distance of stars you have to measure by light years.
Why do we measure the movement of stars?
Parallax is the apparent change in position of an object when you look at it from different angles. Astronomers often us parallax to measure distances to nearby stars. This method can be used to determine stars' distances up to 400 light-years from Earth.
Why is the light year a useful unit for measure distances to stars?
Because it is a large number, suitable for large distances. Astronomers also like to use the unit Parsec.
How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
The universe is so large that astronomers measure distance between stars instead of kilometers?
light-years, parsecs, and megaparsecs
The method astronomers use to measure the distance to stars that are less than 1000 light years from earth?
The method called "parallax.
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.
