Why would a red giant star be brighter than a white dwarf?
because its biger
What is the past tense of some stars appear to be brighter than others?
'Appear' would become 'appeared' in the past tense so the sentence would simply be 'some stars appeared to be brighter than others'.
WHY would Io appear brighter from Jupiter?
Because you are closer to it as it is a moon of Jupiter.
What are Two reasons why one star would be brighter than another?
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.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

What is the main reason that Venus would appear brighter at point Q rather than at point R as seen from the Earth?
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.
Would the reflected image from a concave mirror be brighter or darker than the original image?
It would depend on the distance of the object from the mirror. If the object is close to the mirror, the reflected image may appear brighter due to magnification. However, if the object is far from the mirror, the reflected image may appear darker due to spread out light rays.
Which is brighter mars or Saturn?
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.
What apparent magnitude is ten thousand times brighter than Rigel?
An object that is ten thousand times brighter than Rigel would have an apparent magnitude of about -6. Rigel has an apparent magnitude of about 0.1, so an object that is ten thousand times brighter would be much more luminous and appear as a very bright object in the night sky.
Which moon would look the brightest from the surface of Jupiter out of lo europa ganymede and callisto and why?
Ganymede would appear to be the brightest moon from the surface of Jupiter. This is because Ganymede is the largest moon in the solar system and it has a high albedo, meaning it reflects a lot of sunlight. Its larger size and reflective surface would make it appear brighter than the other moons when viewed from Jupiter.
What are the factor that effects the brightness of a star?
Luminosity, size and distance. If all distances were equal, larger and hotter stars would be the brightest. But a so-so star 40 light years away, will frequently be brighter than a brilliant star 40,000 light years away, etc.
