How does the galaxy affect the earth?

Answer 1

Fairly averagely- it's a spiral galaxy of the larger sort, revolving slowly anticlockwise and of medium age as galaxies go. Our neighbouring galaxies are somewhat closer together in distance to each other than is usual, not exactly forming a cluster but making 'near neighbours' in galactic terms. There are many galaxies in the Universe that are far larger and older than our own Milky way, but also many others that are younger and smaller. Generally speaking, the younger galaxies tend to be in closer proximity to each other than older ones.

What is really amazing, is that there are AT LEAST as many galaxies in the Universe as there are stars in our own galaxy- that's hundreds of millions!! Pretty cosmic stuff, eh?!

The galaxies move farther and farther apart as time stretches across the empty void which is our universe.

Answer 2

Each galaxy is unique, just as each person on Earth is unique. However, there is only 6 billion people on the Earth, and around 100 billion galaxies in the observable universe. There is no galaxy in the universe that's exactly like ours, but there are millions that are very similar to ours.

Answer 3

Our galaxy has human life form on it no other galaxy does - as far as anyone knows.

The Milky Way is not a large galaxy; it could be considered in the low-average size in the observable Universe.

It belongs to the most common galaxy type:

-A spiral galaxy, more exactly a SBc galaxy (spiral barred, with loosely bound galactic arms).

Answer 4

A galaxy is a huge spinning mass of stars in outer space. There are millions of galaxies, each containing billions of stars as well as gas and dust. Our galaxy is called the Milky Way. It contains about 200,000 million stars. :)

Answer 5

The galaxies in the universe are enormous compared to the Earth. They are thousands of light years across while the Earth is only about 12,000 kilometers in diameter.

Answer 6

To a first approximation, not at all. Stars and planets form in galaxies, not outside them, but once they're formed the galaxy really is no longer needed (so far as we know).

Answer 7

They attract each other through their gravitation. This also applies to any other objects: any object in the Universe attracts any other object.

Answer 8

earth might not be the only place where life was created

Answer 9

Mainly through gravity.

Answer 10

In amongst them. In a cluster.
