What causes the apparent brightness or size of stars constellations and galaxies?

The size of stars depends on their mass and the stage of their life cycle. Constellations are just stars which happen to lie in the same general direction from Earth, and have nothing really to do with each other. Apparent brightess of a star or galaxy is the result of its intrinsic brightness and its distance from us.

Which earth motion causes the apparent daily movement of the constellations?
The rotation of the earth around its axis.
Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.

What causes the apparent change in the path of the pendulum?
no
What cause changes in the light coming from distant stars and galaxies?
The apparent redshift is caused by the Doppler Effect; the frequency of waves is increased by an approaching source and decreased by a leaving source. Since the fgrequencies we see from stars are slightly lower than they should be, we know that the stars and other objects are moving away. The Doppler Effect causes changes of light emanating from distant stars and galaxies.
What causes the apparent colors of the objects you see?

What causes the sun to get so hot?
the sun has a process called nuclear fushion, it is nearly what causes the sun's energy and its brightness.
What causes constellations to appear and then disappear?
Constellations doesn't take the same shape forever, as over time, the stars that make up the shape start to move away from each other.
Why can't people in the north hemisphere see all constellations throughout the year?
It is because of the rotation and revolution of the Earth's axis.The Earth goes to one side of its orbit this causes the other constellations to be blocked by the sun. The change in location makes other constellations out of sight. The Earth goes away from these constellations that's why we can't see them.
What causes the light in galaxies?
A galaxy is made up of hundreds of billions of stars (suns). The light from the galaxies comes mainly from those stars.However, in early galaxies, a much larger amount of energy was released from the quasar - currently believed to be the gigantic black hole in the center of galaxies.
Which motion causes some constellations to be visible in New York State only during winter nights and other constellations to be visible only during summer nights?
Earth rotates on its axis.
What process of losing their outer layer causes stars to lose?
