∙ 10y agoAstronomers use apparent magnitide to measure the brightness and dimness of a star, first magnitude stars are the brightest, and can be visible as soon as the sun goes down, but sixth magnitude stats do not appear to be visible until some time after sunset, and are always invisible on moonlit nights and in light polluted cities.

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.
How do astronomers measure distances to stars including the parallax method?
They use the banana method
What unit of measurement do astronomers use to measure the size of stars?
I have usually seen them quoted in kilometers.
What do variable stars help astronomers measure?
Distance.
How do astronomers measure the distance to stars that are less than 1000 light-years from the earth?
Because the angle of shift is very small and extremely difficult to measure, scientists usually use photography to measure the shift. The star is photographed at the beginning and end of a six-month period, and its position in relation to other stars is studied each time.
Why astronomers use to estimate the size of stars?
Because they cannot visit stars and measure their sizes with a tape measure!
What is the standard unit astronomers use to measure the size of stars?
the sun

Usually light-years, or parsecs.

What is the unit that astronomers use to measure the differences between stars and other galaxies?
They do not use units: they use the fact that stars are not galaxies. For example, you don't use units to measure the difference between children and countries.
What do variable stars help astronomers measure?
Distance.
What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
How do astronomers measure distance to the stars?
With a long measuring tape.
What are the different ways astronomers use to study stars?
the astronomers use Absolute magnitude
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.
