Same thing as local stars like the Sun are made of; predominantly hydrogen, which is being 'burned' through fusion into helium. We can determine this mostly from absorption or emission spectra, a characteristic 'signature' of the elements they contain. There is a class of star called a Wolf-Rayet which is mostly helium. One should note that, so long as the fuel being consumed by the nuclear processes has a nett output of energy they can continue to burn elements 'down' the Periodic Table.. but they consume subsequent elements faster and faster, getting less and less energy out of each, until they hit Iron (atomic number 26) at which there is no nett energy output. Our sun for example, once it is exhausted, long after it's a white dwarf, should end up as crystalline iron since its mass is not high enough to become a neutron star. For more information see the theory of stellar evolution, the supporting Hertzsprung-Russell diagram, stellar classification, and the proton-proton chain/CNO cycle.

How do you know what distant stars are made of?
The light spectrum coming from the planet. Each element has its own distinct color spectrum.
Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
What is the main use of the telescope?
to see a distant objects..like stars..
Do distant galaxies rise and set like the stars in your sky?
nope
Is a solar system made up of stars and objects that surround it?
Our solar system is made up of one star - the Sun - and everything held in orbit around it. Some distant stars have been determined to have planetary objects surrounding them, too, but there is still more unknown about those than known.
When was Distant Stars created?
Distant Stars was created in 1981.
How many pages does Distant Stars have?
Distant Stars has 352 pages.
Which of the following is not a reason that astronomers have trouble viewing distant stars?
Distant stars give off less light
Who first realized that stars were distant suns?

What is the true shape of stars?
Stars are distant suns, which are roughly spherical in shape.
The visible part of distant galaxies is the galaxies'?
Stars

Distant radio sources that resemble stars?
