What is higher for closer stars A absolute magnitude B red shift C parallax D blue shift?
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.
Why is the sun brighter than all other stars?
The sun appears brighter than other stars because it is much closer to Earth, allowing us to receive a higher amount of its light and energy. Additionally, the sun is a relatively average-sized star, so its brightness is more prominent compared to much larger or smaller stars.
Why does the sun look brighter than other stars?
The sun appears brighter than other stars because it is much closer to us than any other star. The intensity of light we receive from a star decreases with distance, so stars farther away appear dimmer. Additionally, the sun is a relatively hot and luminous star compared to many others, further contributing to its brightness.
What the color of coolest stars?
Orange is the coolest color of stars
What color are stars when they are really hot compared to their color when they are not as hot?
The hottest stars are blue or blue-white, the coldest stars are red. In between, from colder to hotter are orange and yellow and maybe green. A white dwarf star is even hotter than a blue-white star, but it is dead and no longer undergoing fusion.
How does the color of stars from earth differ from their actual color?
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.
How does parallax shift varies with distance?
The parallax shift decreases as distance increases. Objects that are closer to an observer will have a larger apparent shift in position when the observer changes their viewing angle, while objects that are farther away will have a smaller apparent shift in position. This difference in the amount of shift is what allows astronomers to use parallax to calculate the distances to nearby stars.

How scientists determine the distance of stars million light years away from earth?
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
Is the sun or other stars closer to Earth?
the sun is closer ot the earth than the other stars are .
What is closer to earth - the sun or other stars?
the sun is closer ot the earth than the other stars are .
Why does the moon seem so big compared to the stars?
Because the Moon is much nearer than the stars to the Earth.
How do you receive color stars from your flipnote?
one way is, posting for some amount of days, they give you a green star. but it is much easier to buy them

Explain why some stars in the milky way galaxy have a blue shift Doppler effect and other stars in the milky way have a red shift Doppler?
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.
