What is the distance between a galaxy and a star?

Answer: I think what you are asking for is the average distance between any two stars in our galaxy. That number turns out to be about 5 light years, which is very close to the 4 light year distance between our Sun and Alpha Centauri.

What is the distance from one end of the Milky Way galaxy to the other?

If you travel at the speed of light then one end to the other end of our galaxy is 100,000 to 115,000 light years. It contains about 100 to 250 billion planets.

What is the actual distance of the span of the Milky Way galaxy?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies.

What is the distance between Milky Way and Andromeda?

about 2.5 million light-years
Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour.

What is the distance between the Sun and the Milky Way?

Distance Information. The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.

Which is the nearest star to the Sun?

Of the three stars in the system, the dimmest – called Proxima Centauri – is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth – Sun distance. This is slightly greater than the distance between Uranus and the Sun.

How far away are the stars from US?

When we talk about the distances to the stars, we no longer use the AU, or Astronomical Unit; commonly, the light year is used. A light year is the distance light travels in one year – it is equal to 9.461 x 10 12 km. Alpha Centauri A & B are roughly 4.35 light years away from us. Proxima Centauri is slightly closer at 4.25 light years.

How long does it take a star to orbit the Galaxy?

Not every star moves at the same rate – how fast they orbit can depend on where the star is located within the Galaxy. Our Sun, being fairly far from the Galactic Center, takes over 200 million years to circle the Galaxy once. Some of the stars near us are moving faster than us, and some slower.
