The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.

What characteristics do scientists measure to determine the temperature and composition of stars?
the light radiated from the stars
How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
What is the definition of Astroable?
an instrument used by sailors to determine their location by observing the positions of stars
Which instrument do you use to see stars and planets?
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
Are stars reflected light?
No. Stars emit light.
How do scientists determine a stars composition?
Light wavelength and light spectrum i believe.
What characteristics do scientists measure to determine the temperature and composition of stars?
the light radiated from the stars
What are Binary stars used to determine?
The masses of the two stars.
How do scientists determine the chemical makeup of the stars?

Why is light an important tool used in astronomy?
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
What is Often used to determine the distance to nearby stars?
parallax
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.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
What is used to help humans determine temperature of the stars?
spectral analysis
What used to help humans determine the temperature of stars?
spectral analysis
Why are stars important to navigators and astrologers?
Stars have been used for centuries as a natural means of navigating the Earth. Stars are often used to determine the navigator's location. Astrologers use stars mostly for predictions in astrology.
Could parallax be used to determine the distance of all stars?
