Which is bigger Solar System or Galaxy or Universe?

The universe contains approximately  200,000,000,000,000,000,000 (200 BILLION BILLION) stars in galaxies scattered throughout the universe.  Our solar system is located in one of the spiral arms of the Milky Way galaxy.  The Milky Way galaxy contains approx. 200,000,000,000 stars.  \n\nThe universe is the largest of the three organizational structures in your question.  \n\nHope this helps!

Chance.\n\nMany stars in the galaxy are part of binary systems.  As the gaseous nebula that forms a solar system collapses, the mass can distribute in many ways.  The Sun got the majority of the mass, and Jupiter carries much of the residual mass of the solar system (2.5x the mass of the other planets).  If more mass had gone to Jupiter, we might be in a binary solar system.  If the majority of the mass went to Jupiter, it would be the Sun, and vice versa.

Universe in general is the area of everything including earth, solar systems, nebulas, black holes, galaxies etc are contained within. Everything that is observable to us(human) are so far within this universe. So maybe there are more but to human.. there is only 1.

space doesn't really have limits that we'll ever reach, but yeah there are MANY others planets and solar systems in our galaxy, let alon the other 51351351354 (to the 80 trillionth power) galaxies. it's infinite.

no it's nothing bigger. space is the universe. that's why it's called the universe(uni meaning one) because there is only one of it. space is vast and it is the something bigger

Our Universe is the only one that we know of.  Within our universe are at least a hundred billion galaxies.  Within our galaxy (assuming it is normal) there are a hundred billion stars.  That gives us (assuming the averages hold true) roughly 10,000,000,000,000,000,000,000 (ten sextillion) stars in the known universe.

We can only give a rough guess as to how many galaxies there are, and it's billions at least. All but the closest ones visible as galaxies to the naked eye have names. Our local galaxy is the Milky Way, which you can see in a dark place on a clear night as a streak of stars running across the sky. A cluster is a group of galaxies.\n\nSome galaxies we have discovered with Hubble and other new telescopes seem to crashing into each other, and the Milky Way may be on its way to having a galactic interloper in the far future.

Space is not empty nor is it mostly empty.  Just because you don't see what is between one galaxy and another does not make space empty.  Most of the matter that makes up the universe is not visible.  Therefore the apperant emptiness of space.

A planet is classified by its size/mass.  They are currently reveiwing the catagory, which may end up in pluto being excluded from the solar system.  \nAs far as getting to another galaxy, there is a way, we just haven't figured it out yet.  The closest galaxy is andromeda (sp), which is billions of lightyears away.  And since we can't even reach the speed of light, well, intergalactic travel isn't very likely in the near future.

Well, just our own galaxy is around 1 x 10^18 km across (or 1 x 10^21 m). Lets scale it down to the diameter of the Earth  at 12,750 km, or lets call it around 1 x 10^7 m. This means we would have to scale down the galaxy by a fact of 10^14.\n\nOn this scale, the Earth would have a diameter of around 1 x 10^-10 m. This is about one ten thousandth the diameter of a human hair. So a galaxy the size of the Earth would have and Earth 1/10000th the size of a hair.\n\nIt does not help our concepts of the scales to continue this to the Universe - its just very very big.

Of course the size of this galaxy and universe are beyond human undestanding, I know this scientist did a math formula where he put the very least possiblities of life and the number was still huge.\nEx, he did like in one galaxy there is only X planet where there is water and only X springs life and only X becomes civilized, and in the end he figurd there tons of life out there!

The Milky Way galaxy, our galaxy, is 80-100 thousand light years in diameter, and about 3000 light years thick.\n\nA light year is the distance light travels in one year, so it is a measure of distance and not time.  One light year equals about 5,878,499,810,000 miles.

The universe is big enough to contain over 100 billion galaxies, of which the Milky Way is one. It is also expanding. Since it is growing larger, it can't be infinite, since infinitely-sized things can't become larger than infinity.

There's The Universe, then there's the observable universe. No one knows the size of the first one; it's probably infinite. The second one is the universe with a boundary; that boundary is how far we can see into The Universe, about 13.7-billion light years.

Yes.  Beyond our own Milky Way galaxy there are estimated to be 200 billion more galaxies in the visible universe at distances up to 13 billion light years from Earth.

Your thinking is good, but you have to take into account the distance scales involved. On the scale of the entire universe, space is indeed expanding, but on the relatively tiny scale of distances in our solar system, the expansion is miniscule. Also, the gravitational forces involved with holding the planets in their orbits around the Sun easily overcomes the expansion rate.

i don't think in terms of the universe being massive compared to the size of galaxies,but minuscule compared to that which is outside the universe, that way there is an endless supply of material on hand.here at the"center of the universe"it's all relative to our thinking everything is so large but since all we can do is theorize about whats out there,why cant we theorize outside the box,way outside the box. where did science get this idea ? i believe that a chaotic set of galaxies brings about an ordered universe that is a single organism of a larger set of chaotic universes,which in turn forms ordered groups of galactic multiverses which is a small component of a megaverse ,and so on
