Why is the sun the brighter than other stars?
It's a lot closer to the Earth than any other star. The second closest star to the Earth is 5 Light Years away. The Sun is 8 minutes away from the Earth, traveling at the speed of light.
When light from a star reaches earth is the star still there?
Yes. It is a common misconception that the light from a star takes millions of years to reach Earth, and that the star is dead by the time the light reaches us. This is false for two reasons. First, most of the stars you can see with the naked eye are no more than a few hundred light years away and some are less than 10 light years away, so the light we see from them was emitted hundreds of years ago at most, not millions. No star in this galaxy is more than about 75,000 light years away. Second, for most stars, a few million years is a fairly short time. Most stars last for billions of years.
Why earth receives more energy from the sun than from any other star?
Because it is the closest star to earth, meaning less energy is lost to the cosmos on its journey towards earth.
Are the stars farther than the moon?
Each star is another solar system. If a star (a sun) was closer than the moon the earth would burn up into nothing.
What is a star call when it is moving away from the earth?
A star moving away from the earth is still called a star, but the color of the light that we see will be "redder" than it actually is. This is called redshift, and a link can be found below for more information.

How may light years is mercury from earth?
Less than 1.
Why does the sun appear brighter than a star?
The Sun is much, much closer to the Earth than any other star - eight light minutes vs. four light years for the next nearest star.

What star is other than closest to earth?
The Sun is the closest star to Earth. The next closest star is 4.2 light years away. It is a red dwarf called Proxima Centauri.
Why would a star that is farther away from earth be brighter than a star that is closer to earth?
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.
Why earth receives more energy from the sun than from any other star?
Because it is the closest star to earth, meaning less energy is lost to the cosmos on its journey towards earth.
Has Pluto ever had light?
Yes. Pluto gets light from the sun, but far less than Earth does.
Is the nearest star one light-year from the solar system?
No, the nearest star to the Earth, other than the Sun, is Proxima Centauri and it is 4.2 light years away.
If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?
No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
How many years does starlight travel?
It depends on the distance of the star to Earth. The distance to the star in light years is the number of years the light took to get here. Most of the stars we see at night are within a few hundred light years of Earth. The closest star other than the sun is about 4.2 light years away.
How is the distance measured of stars less than 1000 light years away?
The parallax method is usually used in this case. Earth's movement in its orbit cause an apparent shift in position in such a star.
