How many Earths can fit in the Milky Way?

Answer 1

There are eight planets in our Solar System.

As of May 2010, 455 planets have been found outside of our Solar System.

There are an estimated 200 -> 400 billion stars in the Milky Way Galaxy.

So there are likely to be billions of planets in the Milky Way Galaxy.
There are 8 Mercury Venus Earth Mars Jupitar Saturn Uranus Neptune (Pluto is a dwarf)

Answer 2

The number would be too large to post.

To give you some idea, if we made a "chain" of earths from Pluto to the sun (just one line of them, back to back) it would be about 362,500 of them. If you want to fill this solar system up with earths, multiply that by a large number... There are 200-400,000,000,000 solar systems in this galaxy (the milky way) and the spaces *between* stars are much much, much larger.

So yeah, it would probably be a long long page filled with many zeros.

Answer 3

If the Milky Way was thediameter of a football field--end zone to end zone and you stood at a table at the fifty yard line with a microscope,our entire Solar System out to the Oort Cloud would be a 1 mm dot on your microscope slide. The earth, in loose terms would be smaller than a hydrogen atom within that dot and you would not even be able to see it, even with the most powerful microscope!

Answer 4

That is currently not known, but based on recent discoveries of exoplanets, it seems there are probably several planets for every star, on average. There are somewhere between 200-400 billion stars in the Milky Way.

Answer 5

There are millions, possibly billions, of planets in the Milky Way. An exact number will never be known.

Answer 6

There are more than 70 solar systems in the Milky Way galaxy. Scientists find new ones every year!

Answer 7

Who knows. There will be trillions and trillions of them.

Our asteroid belt contains about 2 million objects larger than 1km with millions more smaller ones.

Answer 8

Impossible to say.
