Why does earth get more energy from the sun than from all other stars in the universe combined?
The other stars are so distant that most energy is lost to space. Radiated energy uses the "inverse square" law- 2 x as far= 1/4 as much, 4 times as far = 1/16th as much, etc. 10 times as far=1/100th as much. The other stars are MILLIONS of times further away than the sun.
Are all the stars you see from earth suns?
Yes, all of the stars that you can see are other 'suns' like our own, or more accurately, our sun is a star, like the others you see at night. There are a lot of different types of stars, they vary a lot in size, temperature mass and composition, but they are all similar in that they burn fuel through nuclear fusion. A lot of them are in groups of two or three, though our sun is on its own. Each of the stars that you see at night may have several planets in orbit around them, similar to our solar system (but too small and dim to see from these distances). The other stars are much, much more further away than our sun.
How many stars are in constellation Vulpecula?
A constellation is basically a direction in the sky. The further you go (or the weaker the stars you include in your count), the more stars you will find.A constellation is basically a direction in the sky.

Are there more stars in the universe compared to all the grains of sand from all the beaches around the world?
There are many more stars than there are grains of sand on earth. See link.
What planet would have no advantage of any kind over earth for making parallax measurements?
You have to ask yourself what is an advantage when parallax measurements are being made? . . parallax happens when you move to a different place and the object you see look a little different, the closest ones appear to have moved more than the ones that are further away. In astronomy parallax is created when the Earth is in opposite points of its orbit. Stars that are close appear to have moved a little, relative to the mass of stars that are a long distance away. Parallax was not observed before the 19th century, and the lack of parallax was always used to 'prove' that the Earth could not possibly be going round the Sun. It was only in the 19th century that parallax was observed, but it was only very tiny movements of the closest stars. It forced people to realise that the stars are incredibly far away and the Earth does go round the Sun after all, so it was extra evidence of the Sun being at the centre of the solar system. A parallax measurement is easier to make if the baseline is longer, so the answer to your question is that Mercury and Venus have no advantage for making parallax measurements.
Does the medium of space make distance stars appear to be more red shifted only because they are farther away?
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
How do the stars and moon collide?
They don't. The stars are nuch more distant than the moon. Consider this for how much further away the stars are: Light, which travels at a constant speed, takes a little more than a second to travel from the moon to Earth. Light from Proxima Centauri, the nearest star other than the sun, takes more than 4 years to reach Earth.
Why does the sun appear brighter than other stars from Earth?
The Sun is the closest star to Earth, so it appears much brighter than other, more distant stars.The Sun is eight light-MINUTES away from the Earth. The NEAREST other star is 250,000 times further away.
How much farther is canopus from earth than sirius?
These are the 2 brightest stars in the sky. However Canopus is a lot more luminous because it is much further away. Canopus is about 310 light years away. Sirius is only 8.6 light years away.
Why does Venus take more than a year to go around the orbit?
because its further away from the earth
Why have none of the stars from the big dipper ever fallen?
The stars are unimaginably far away, well beyond any influence from Earth. Even then, they are far larger and more massive than Earth is.
Are there more stars or more ants?
I would have to say there is more stars. The universe is alot older than Earth and there are just more stars that formed before Earth. But there are a lot of ants, just not more than stars.
Why is it hotter is summer?
It is hotter in the summer because of the tilt of the Earth on it's axis. The sun is further away but the rays are more direct.
When stars fall do they become rocks?
No. Stars cannot fall to Earth They are far beyond the influence of Earth's gravity and far larger and more massive than Earth. The stars are suns, some larger and brighter than our own but unimaginably far away. The remains of dead stars are composed of extremely dense forms of matter not found on Earth. The "falling stars" are not actually stars; they are meteors, small pieces of rock and metal that burn up as they travel through Earth's upper atmosphere at extreme speeds.
How many miles away is the farthest star?
We'll never know because stars that are further away are dimmer, so the furthest ones are very dim, so we have to assume there are plenty more which we can't see.
Why does a medium sized stars appear brighter than the others?
The Sun is the closest star to Earth, so it appears much brighter than other, more distant stars. The Sun is eight light-MINUTES away from the Earth. The NEAREST other star is 4.2 light years away (Proxima Centauri).
Why don't stars fall down?
Because the Earth is far too small and far away to pull in stars. Things "fall down" because of gravity, which in turn is caused by the gigantic mass of the Earth. This mass attracts other objects with mass, like, say, a ball, which makes the ball and Earth move towards each other. Of course, because the ball is incredibly small compared to the Earth, the amount the ball moves much further than the movement of the Earth. Stars, on the other hand, are several thousand times more massive than our Earth. This gravity is the main reason why our Earth orbits around the Sun, our own local star. Most stars are many millions of billions of miles away from us, so their gravity has no effect on the Earth, and vice versa. However, if we were close enough to a star for it to "fall", it would be more likely that we would end up falling into the star, as we'd be comparable to a ball falling to Earth.
