Distances to stars are mainly measured in PC (Parsecs).
Light years are also used because the distances covered are so great.
For example. Proxima Centauri our nearest neighbourhood star is:
Light years: 4.23
Parsecs(PC): 1.3009.
If we used miles then the distance would be:
24,866,054,200,000
or kilometers
40,018,035,200,000
Which one is the easiest to remember and that is your answer
What else can I help you with?
Do Astronomers measure distances to stars in units called kilometers?
Well Yes, if you don't mind running into tons of 0s. A better way to measure it is using light years. It takes one year for a beam of light to travel 10,000,000,000 kilometers. A light year is 10 trillion kl.
Distances in our Solar System are measured in?
Normally in Astronomical Units (AU) which is the average distance from the earth to the sun.
Why do you think stars very in brightness?
because they are different sizes and different distances away from earth
What are the specks of light in a galaxy?
stars i think...
What is used to measure a stars distance if it can not be measured by parallax?
A million light-years is about 300,000 parsecs; that would mean a parallax of 1/300,000 arc-seconds. Such a small angle can't be measured yet.A million light-years is about 300,000 parsecs; that would mean a parallax of 1/300,000 arc-seconds.

Do stars emit light or reflect?
Stars generate and radiate their own light. This is pretty obvious when you think about the star that's closest to us ... the sun.
A distance measured in meters is more than a distance measured in kilometers?
Assuming it is the same distance, the distance in metres will be a larger number than the distance in kilometres - but the two distances will still be the same.
Why is light year used to measure the of stars?
No because the wavelength is determined by the star radiating the light. But over large distances from far-off galaxies there is a slight shift in the wavelength called the red shift, and the distance can be measured by the amount of red shift.
Why do you think meteors are shooting stars?
Because stars are rocks that get their light from the sun and if they die, (stars can die), they simply fall or they just stay there in the sky.
What are the examples of source of light?
sun stars fire Many people think the moon is a source of light, but it only reflects the sun's light.
What types of a body in space give out their own light?
I have only one body to answer this question. That is a star. The star uses nuclear fusion, which is emiting light.
Can light waves travel on a vacuum?
I think they can, since that's how you see the sun and the stars.
