A star moving toward the sun will show?

Answer 1

Just chance. Some stars are very close to each other. Some are in binary systems that are two stars rotating around each other. Some are so close that one rips the material of ft he other. The center of our galaxy is full of stars that are relatively close. We just happen to be on the outer edge of our galaxy where there aren't many stars.

Answer 2

Now, the earth has water on its surface and this deformable matter is distorted by the gravitational field of the moon, to give two bulges. However, the earth spins so quickly compared to the orbit of the moon that these bulges are distorted and pull the head by the rotation of the earth. This is why the tides on earth always lag with the moon passing overhead by a couple of hours. However, this gives the earth a peculiar shape witch has the effect of accelerating the moon at the cost of slowing down the rotation of the earth. The transfer of energy to the moon moves it into a higher orbit and gains potential energy witch perversely has the effect of making the moon orbit more slowly. Oh yes, even simple orbital mechanics can be a mind bender. It seems reasonable to suggest that the current state of the continents, forming essentially two land bars around the earth, maybe particularly apt to this transfer of energy from the earth's spin and the moons orbit. However, this is not how the water on earth and the continents have always been arranged. Measuring the current rate of lunar recession, it is comparatively easy to measuring the rate of lunar recession in prehistory (Pangean times, 180 million years ago). Although, those who have attempted such calculations estimate the in pangean times, the rate of lunar recession may only have been half of what it currently is.

Answer 3

This is a little complicated, but actually quite logical:

1. The Moon produces tides. Energy can be obtained from tides. The energy from tides can also be wasted, as friction. Ultimately, the energy for the tides comes from the Earth's rotation. Therefore, as a result of conservation of energy, the Earth will gradually rotate slower.

2. There is also a law of conservation of rotational momentum. If the Earth rotates slower, the Moon moves farther away - thus, rotational momentum is conserved.

Answer 4

I'm not sure what this question is supposed to mean, but it could be:

1. Because there is more area as you move from the pole towards the equator, so naturally you would expect more stars there.
2. Because the direction towards the center of the Milky Way galaxy is in Sagittarius, which is near the celestial equator, so naturally you would expect more stars there.
3. Because they have to move further to complete a circle in the 23 hours and 56 minutes that make up a sidereal day.

Answer 5

Within our local area of stars, some are moving away and some are moving toward us as all these stars follow their own orbital paths around the center of the Milky Way galaxy. Some other galaxies are moving toward us; for example, the Andromeda galaxy will collide and merge with the Milky Way in about 4 billion years or so, which is about when our Sun will turn into a red giant and incinerate the inner planets. We'll probably want to start thinking about moving the Earth to an orbit around one of the newer stars.

Further away, most of the other galaxies are moving AWAY from ours, a fact Edwin Hubble explained by coming up with a principle of universal expansion.

Answer 6

It isn't the stars that move but the Earth turning on its axis. That's why the north star appears to be fixed, from our point of view it is on the northern axis (at the north pole, it would be directly overhead, at 23 degrees N latitude it would be 23 degrees above the horizon). In reality, these stars are hurtling through space, as are we but in various directions; it will be thousands of years before Polaris appears to have moved.

The "proper motion" of a few stars have been measured on photographic plates taken years or decades apart. The most famous is Barnard's Star a very low-mass red dwarf star about six light-years away from Earth. In 1916 E.E. Barnard measured its proper motion as 10.3 arc seconds per year, which remains the largest-known proper motion of any star relative to the Sun.

Answer 7

The sun is relatively close to some of the planets, and relatively far away from the others.

The reason that the sun is located at the distance from us that it is, is: If it were

significantly closer to us, or significantly farther from us, then life on Earth would

not be possible, and we would not be here to ask questions about the sun.

Answer 8

Unless it's moving at relativistics speeds it will look like any other star in the sky. If it moves at relativistic speeds (very close to the speed of light) then it will look redder than it is.

Answer 9

This is a little complicated, but actually quite logical:

1. The Moon produces tides. Energy can be obtained from tides. The energy from tides can also be wasted, as friction. Ultimately, the energy for the tides comes from the Earth's rotation. Therefore, as a result of conservation of energy, the Earth will gradually rotate slower.

2. There is also a law of conservation of rotational momentum. If the Earth rotates slower, the Moon moves farther away - thus, rotational momentum is conserved.

Answer 10

If I am interpreting your question correctly, I think you are referring to a shooting star which can be seen randomly with the naked eye in the night sky. I will follow up this question with a more detailed answer if you reply.
