Stars vary widely in size and brightness. A nearby white dwarf star may produce much less light than a much more distant blue giant, in the same manner that a far off floodlight may outshine a close-by candle.

Three possibilities: It is brighter (some are brighter than others), it is bigger, or it is closer to earth.
An object have greater gravitational pull closer from earth. As we get farther from earth, the gravitational pull becomes weaker. That is why objects sufficiently away from the earth do not fall on it.
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
If the Sun were larger or closer, the Earth would be too hot to be liveable. Or if it were weaker or farther away, the Earth would be completely frozen.
You would move farther away from the equator because of the tilt of Earth's axis.
Saturn is brighter than Mars in our night sky. Saturn's rings reflect more sunlight, making it appear brighter from Earth. Mars is usually visible to the naked eye and has a reddish color, while Saturn has a yellowish tint.
If two stars have the same absolute magnitude, the one that is closer to Earth will appear brighter in the night sky. This is because brightness as perceived from Earth depends on both the intrinsic luminosity of the star (absolute magnitude) and its distance from us. The farther star, despite having the same intrinsic brightness, will have a dimmer apparent magnitude due to the greater distance light must travel to reach us.
It changes all the time, as Earth gets closer to, and farther from, the Sun, in its yearly orbit.

The main reason Venus would appear brighter at point Q rather than R is due to the angle of illumination. At point Q, Venus is closer to the Sun, so it is receiving more direct sunlight, making it appear brighter. At point R, Venus is farther from the Sun and receiving less direct sunlight, resulting in a dimmer appearance.
Which body? The one casting the umbra or the one on which it fell? Try it this way: If the Earth and the Sun stayed the same distance apart but the Moon was closer to the Earth, the umbra it made during eclipses would be larger; if it were closer to the Sun (i.e., farther from the Earth) the umbra would shrink, perhaps to nothingness, and only the penumbra would fall on the Earth.
