please answer this science question?

Question

give me two reason why one star may appear brighter than another star???

Answer 1

Distance of the star from earth.

Original size of the star.

Answer 2

There is multiple reasons. Here is two of them:

The kind of stars it is will determined it is a bright star or not. Also, the distance from us and if its revolution is toward us will change the way we see it.

A very bright star really far from us can appear brighter than a faint star near from us.

Answer 3

the distance the star is from us plays a roll in the brightness so if one is closer it may be brighter. also as a star goes through it's life cycle it gets brighter and then goes out so one star maybe in its prime while another is just starting to shine...

Answer 4

Some reason that i know:
-the temperature of star
-the distance of star
-an old star
-If you talk about star in the skies(not a real star),it might be an space phenomenon like supernova, nebula, or anything.

Answer 5

I can only think of two factors that affect a star's brilliance:

1. Distance from Earth
2. Age of the star

Answer 6

Distance from the viewing point.

Age of the star.

Answer 7

--Because in fact they have different intensities, and are all of different color! A Biblical reference to this scientific truth is:

(1 Corinthians 15:39-41) “. . .. 40 And there are heavenly bodies, and earthly bodies; but the glory of the heavenly bodies is one sort, and that of the earthly bodies is a different sort. 41 The glory of the sun is one sort, and the glory of the moon is another, and the glory of the stars is another; in fact, star differs from star in glory.”

“STAR DIFFERS FROM STAR”

Science textbooks are often no sooner printed than they are out of date, so frequently do new discoveries nullify old convictions. Yet, though written centuries before telescopes and microscopes were even conceived of, the Bible often speaks about scientific subjects with remarkable accuracy.

One instance is at 1 Corinthians 15:41 where the apostle Paul says: “The glory of the sun is one sort, and the glory of the moon is another, and the glory of the stars is another; in fact, star differs from star in glory.”

To the casual observer most stars look alike, except perhaps for their difference in brightness. Astronomers nevertheless say that stars also vary in color, from white, bluish-white, yellow, orange, orange-red to red. Pulsars—believed to be fast-spinning collapsed stars—have a rather unique “glory.” Like clicking turnstiles, they flash radio signals with split-second regularity. The Crab and Vela pulsars even flash visible light. Stars differ greatly in density. They also vary greatly in size. The supergiant Betelgeuse is, according to conservative estimates, more than 250 million miles (400 million km) in diameter! If it stood in the place of our sun, Betelgeuse would engulf the earth and the rest of our solar system clear out to where Mars orbits!

How could the apostle Paul have written scientific truths when he did not even have an instrument as crude as Galileo’s to inform him? Divine inspiration is the logical answer.

Awesome Star Power

A recent Hubble image provides further evidence that a star in our galaxy is a rare type of star called “a luminous blue variable.” According to astronomers, the brilliant star and surrounding nebula is shaped like a gun, hence it has been named the Pistol. It is estimated that the Pistol is at least 60 times as massive as our Sun and nearly 10 million times as powerful. It could be “the most energetic star in the heavens,” says Science News magazine. But because of intervening dust, the star can only be detected with infrared detectors. That explains why the Pistol, which is located 25,000 light-years from Earth, was not discovered until the early 1990’s. Only six other stars of this type have been detected in our galaxy

--AND ALSO they are of different distances from us and each other!

Answer 8

temperature of the star & distance of the star from us

Answer 9

1. distance

2. size (big stars - even if cooler - have larger areas so give out more light)

Answer 10

becaus it might become old,i don't know
