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)
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.
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!
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.
There are millions, possibly billions, of planets in the Milky Way. An exact number will never be known.
There are more than 70 solar systems in the Milky Way galaxy. Scientists find new ones every year!
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.
Impossible to say.
I don't really like milky ways. Reese's cups are better.
The sun could fit over 1.3 million earths inside of it. Wow... see https://fretzreview.wikispaces.com/Milky+Way,+Universe,+Light+Years
467,200,345 earths fit in the sun
6,000 earths
Approx 23 trillion trillion trillion (2.3*10^37).
One.
the solar system
approximately 109 earths would fit around the circumference of the sun
Yes. Comets are tiny; the Milky Way is enormous.
you can fit 833 earths in saturn.
3 earths
if the Milky way galaxy has roughly 100 billion stars in it like scientist believe. and the odds of this happning are one in one million. when you do all the math it works out to be 10000 earths in our solar system. but that's only if there really is one earth in a million stars. its almost impossible to know for certain
