solar systems how many gallaxy's like ours

If your question is : "how much space is in the solar system?" --\n\nThe solar system is a sphere occupying approximately 7.244^29 (7.244 followed by 29 zero's) miles\n\nIf that's not your question then I don't have the foggiest notion of what you're asking.

No.\n\nGalaxies are groups of stars and planetary systems.\n\nA single sun (even ours) is not powerful enough to have a galaxy rotate around it (gravitationally speaking).\n\nDoesn't work that way.  We move around inside the galaxy, not the galaxy around us.

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.

With an orbit of where earth is, 149,600,000 km, that's a surface area of 7.12383E+15 km², i think...\n\nYou can fit approx. 11,700 earths in a single ring around the sun, so you can imagine the amount of materials needed for a dyson sphere is pretty massive! (although Jupiter is more than a 1000 times more massive than the earth!)\n\nI think you might even need to destroy whole solar systems to get the materials required, but the planets, moons & asteriod belt would be a good place to start, assuming you need specific materials like metals especially.\n\nDon't even think about the cost!

Currently, we have discovered 10 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Sedna), but there are smaller planets called transneptunian objects that are very small and cannot be detected by current technology. Carla is probably a transneptunian object.

in relation to the other planets in our solar system... our moon is bigger than pluto but smaller than the other planets.\n\nin relation to other moons of other planets in our solar system... it is the 5th largest out of all the other planetary satellites.\n\nthe exact figures are at the link below:\n-(this other link might help as well)

Once a scientist tried to calculate it by math, he said that only in our galaxy there are about 100 million suns, our sun has 9 planets to follow, while other suns could have more or less, so he said that each star could have 5 planets medium, this makes 500 million planets in our galaxy , medium , then he said that 1 of each 100 planet could be warm like ours , this makes 5 million planets , and one of each 100 of those , could have suitable gravity and atmosphere and so a sort of life , this makes 50 thousand planets , and one of each 100 of those has some forms of intelligent life, this makes it 500 planets only in our galaxy.\n\nbut the equation is much easier, our earth is like a grain of sand in its own solar system , why could it be the only form of intelligent life host in the whole universe ?\n\nI believe that some sorts of intelligent life on other planets are asking the same question of yours, and they could never know that we even exist.

here is a calculator for determining planet and orbit sizes to scale.  i hope this helps.\n\nhttp://www.exploratorium.edu/ronh/solar_system/

There might be a million planets in space, but not in our solar system...

Yes, and I can prove it mathematically:\n\nOur galaxy (the Milky Way) contains at least (by most estimates) 100 billion stars. Now thanks to the Hubble space telescope, we know for a fact that there are other solar systems out there. So let's be conservative and assume that just 1% of the stars in our galaxy have planets in orbit around them.\n\nThat's 1 billion other solar systems.\n\nNow, of those solar systems, let us assume that a further 1% have a planet that is just the right distance from the star to support life.\n\nThat's 10 million planets where life is possible.\n\nAnd if on just 1% of those planets, life actually formed, then there are 1 million planets in our galaxy that have microscopic life on them.\n\nNow let's assume that of that total, 1% have life evolve to any level of significance (creatures with a rudimentary intelligence). \n\nThat gives us 10,000 planets that actually have alien species on them.\n\nAgain, let's go with 1% and say that's the number of planets on which life developed any significant degree of intelligence and formed a civilization.\n\nThe end result is that there are at least 100 planets in our solar system that support life at least as intelligent as we are.\n\nNow, consider that our galaxy is one of an estimated 125 billion galaxies in the universe.\n\nThat gives you over 1 trillion alien civilizations scattered throughout the known universe.\n\nFrankly, it is scientifically impossible that we are the only intelligent species.\n\nAs for whether any of them have made contact with us... no, I don't believe so. You're talking about 100 planets in a galaxy of over 100 billion stars. The odds against any two of us making contact are just too great.

solar system is the system which includes the sun and the nine planets along with the satellites of each planet , asteroids , meteorites.

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.
