How many Galaxys are in your Solar System?

Answer 1

If it can be proved that each star in the Milky Way Galaxy has it's own collection of planets, asteroids and other space stuff (making a solar system) - and it seems more than likely, then given that about 50% of all star system are comprised of a binary (or more) star system, then there are between 100 -> 200 billion single stars in our Galaxy.

Answer 2

Well, there are a very large number of stars - estimates range as high as 400 billion. (Many are too small to see, and the dust clouds around the center of the Milky Way prevent us from seeing straight through it.)

At one time, astronomers thought that planetary systems were probably very rare; perhaps as many as one star in 10 might have planets. Now, with every improvement in space telescopes and computers, we discover more and more planets. There may be planetary systems - solar systems - around many, perhaps even most, stars.

Answer 3

A "solar system" is what we call a star and everything gravitationally bound to that star.

Estimates of the number of stars in the Milky Way Galaxy range from 100 billion to 400 billion,

and it's thought that the formation of planets is a rather common occurrence during the formation

of stars. So there is definitely enough room for 400 billion solar systems in the galaxy, and it's

likely that nearly that many actually exist.

And that's just in this one galaxy.

Answer 4

This varies extremely from galaxy to galaxy, from tiny galaxies with 10 million stars, to huge ones with 1000 billion stars.

The average is somewhere between 100 and 1000 billions.

An exact number is hard to give, as we don't even know the number of stars in our own galaxy (between 100 and 400 billions). And there are 170 billion galaxies in the observable universe, so counting the average number of stars could take a while

Answer 5

It used to be dozens of planets in the early solar system but they all collided to make bigger planets. Now there are 9 planets in the solar system. Pluto is not a planet anymore as it's considered a dwarf planet. The 9th one is 2003 UB313 and it was discovered in January, 2005. It is 3 times farther from the sun than Pluto.

Answer 6

We don't know; a LOT, for sure. Every time we invent new, more powerful telescopes and point them at "empty" spots in the sky, we see..... more galaxies.

We're certain of "BILLIONS and BILLIONS" of galaxies, as Carl Sagan said 30 years ago. But it looks like Sagan was wrong; he should have said "billions OF billions".

At some point, numbers become meaningless and mind-numbing, like the national debt or the number of stars. Any guess is certainly wrong, and probably way too low.

Answer 7

NONE!!!! There are no galaxies in the Solar System.

It is the other way around.

The Solar System is in the barred curved tail of a spital galaxy, named the MILKY WAy.

Answer 8

About 300 billion.

And there are at least around 30 billion galaxies around the same size - do a Google image search for "hubble ultra deep field" to have your mind blown.

Answer 9

The estimate of the number within visible range is billions, and we don't know

how far the universe extends beyond our visible range.

Answer 10

The solar system is part of the milky way galaxy.
