Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
The answer would be C) Parallax.The Absolute Magnitude of a star is the star's actual brightness, and is therefore not dependent upon the position of the observer.Red Shift and Blue Shift are consequences of a stars speed relative to the observer. Again this is independent of the stars proximity to the observer.Parallax, is the apparent change in position based upon the motion of the observer, and is directly proportional to the proximity of the object. Just as, when driving on the road distant trees or buildings don't appear to zoom past you as quickly as a pedestrian on the side of the road, so it is with stars. The closer they are the larger the parallax is as the Earth orbits the Sun, for example.
Orange is the coolest color of stars
NO. Stars have difference colors depending on their temperature. The hottest stars are blue and cold stars are red.
stars get there color by people going into space and them coloring them with piant. thats how stars grt there color
Because it is way closer than other stars!
Since the stars are not stationary in relation to earth, i.e. they are moving towards or away from the Earth, their light will be subject to Redshift (if they are moving away) or Blueshift (if they are getting closer). The faster they are changing distance, the greater the shift in wavelength.
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
The closer the star, the greater the parallax angle, which is why you can't measure the distance to very distant stars using the parallax method.

i know astronomers use paralax for stars thay know by red shift if ther moveing away and blue shift if coming closer may some galaxies are so far there lite wont reach us
the sun is closer ot the earth than the other stars are .
the sun is closer ot the earth than the other stars are .
The redshift that scientists speak of in stars, indicating that they are moving away, is complemented by a shift toward the blue in the spectrum by light moving toward a viewer.
Because the Moon is much nearer than the stars to the Earth.

A blue-shift means an object is moving towards us, a red-shift means it is moving away from us. Blue-shift and red-shift are changes in frequency of the light we receive, due to the relative movement. This is called the Doppler effect.
one way is, posting for some amount of days, they give you a green star. but it is much easier to buy them
