Does anyone know how many constellations there are?
438209
According to the International Astronomical Union (the official policy making body for astronomers) there are 88 constellations.  Each constellation has its own 'border', and every object in the sky falls into one of those constellations.  The best picture I could find is below.  I hope this helped!

There are not an infinite number of stars, but there are billions and billions. The universe is not infinte, as we can see close to the end (boundary) of the universe with telescopes like the Hubble. Because there are so many galaxies and clusters where new stars were being born millions of years ago, because the speed of light is also not infinite, no one can really count them.\nhttp://www.cnn.com/2003/TECH/space/07/22/stars.survey/\nFor more, go here:

Constellations are figments of human imagination.  They are just random stars that appear to have a shape if you look hard enough.

only a few galaxies have names: the sombrero, the milky way, andromeda, the black eye, the pinwheel, the small and large malgentic clouds, the whirlpool, and the spindle are all i know of.\n\nMost go by NGC #### in the new star catalouges.\n\nand we only have found a few galaxies.  There are still almost unlimited more!

There are more stars than we can count.  Most of them have planets.   Most of those planets have moons.

If you mean visible to the unaided eye and defining the dippers, seven each.  In the Little Dipper you have Polaris and Kochab, the others are not particularly bright and have no names, just catalog numbers.\nIn the Big Dipper, one could argue that there are eight visible stars, as the middle star in the handle, Mizar, has another star, Alcor, right next to it.  The two stars at the end of the bowl of the Big Dipper, Merak and Dubhe, point straight to Polaris.

Thats one of the funniest questions I've ever heard, and definately a first.\n\nRatio...lol \n\nEven if someone could give you an accurate number it would be too large a number on the star side to even begin to comprehend, and too small a number on the freckle side to even be able to comprehend.  No one knows the exact number of stars, or even galaxies that contain them.

According to the NASA website, there are 134.*\n\nMercury - 0\nVenus - 0\nEarth - 1\nMars - 2\nJupiter - 62\nSaturn - 31\nUranus - 24\nNeptune - 13\nPluto - 1 \n \nBut there is another website that claims there are 156.**\n\nMercury=0 \nVenus=0 \nEarth=1 \nMars=2 \nJupiter=63 \nSaturn=47 \nUranus=27 \nNeptune=13 \nPluto=3\n\nTake it for what it's worth.

I think there were 12 each time not totally sure and there have been more than 4 sets released as far as I know also.\nI have a few out of several of the sets. Never could get a complete set.

Most ancient cultures saw pictures in the stars of the night sky. The earliest known efforts to catalogue the stars date to cuneiform texts and artifacts dating back roughly 6000 years. These remnants, found in the valley of the Euphrates River, suggest that the ancients observing the heavens saw the lion, the bull, and the scorpion in the stars. The constellations as we know them today are undoubtedly very different from those first few--our night sky is a compendium of images from a number of different societies, both ancient and modern. By far, though, we owe the greatest debt to the mythology of the ancient Greeks and Romans.\n\nThis website should help you a lot.  It talks seperately about 27 of the major constellations of Greek Mythology.\n\nAs far as which stars they saw?  When they lloked up at the skies without telescopes, they saw the same stars (with the exception of newly formed stars) as we see.  What we have been able to identify and name with our higher technology is such a vast list I wouldn't know where to begin.

The observable universe is estimated to contain:\n10^11 galaxies, 10^21 stars, and 10^78 atoms.\n\nThe means 100,000,000,000 galaxies.

As of April 18th, 2006 we know of 152 planetary systems other than our own containing a total of 176 planets.  This number grows fairly frequently as more and more observations are being made.

According to the authority of the IAU, there are nine planets in our solar system. In increasing distance from the Sun they are (with the astronomical symbol in brackets):\n\nMercury (☿) \nVenus (♀) \nEarth (♁) with one confirmed natural satellite, Luna (the Moon) \nMars (♂) with two confirmed natural satellites, Phobos and Deimos \nJupiter (♃) with sixty-three confirmed natural satellites \nSaturn (♄) with forty-six confirmed natural satellites \nUranus () with twenty-seven confirmed natural satellites \nNeptune (♆) with thirteen confirmed natural satellites \nPluto (♇) with three confirmed natural satellites, Charon, S/2005 P 1 and S/2005 P 2 \nHowever, there is some pressure for Pluto to be reclassified as a Kuiper Belt object, especially in light of the discovery of 2003 UB313. This object, however, has not yet received a definitive classification from the IAU.\n\nSedna was widely touted as a planet when it was discovered in 2003, as it was the largest object found since Pluto. However, mainly due to its size still being smaller than Pluto's, it did not achieve planetary status from the IAU. However, the discovery in 2005 of 2003 UB313 (nicknamed Xena), with a size and mass larger than Pluto seems to have forced the issue. As of January 2006 it has not yet been accepted as a planet, but the IAU is expected to announce a definition of a planet soon, which will likely either see 2003 UB313 become a planet, or have Pluto stripped of its status.

That depends. Right now there are 50, one for \n\neach state. The first flag had 13 stars, one for \n\neach colony. In all, there have been 27 different\n\nAmerican flags.

Orion constellation, with three bright stars forming its belt, "las tres Marías" (The three Mary´s). Next to the belt, you will find Orion´s nebulae, a spiral galaxy, like our own. The shoulder of Orion is characterized by Rigel, a bright reddish star.\nClose to Orion, is Can Majoris (the great dog) featuring Sirius, the brightest night star in the whole observable sky from Earth. \nTo the other side of Orion (i.e. to its left and closer to the horizon), there´s a "V" shape with a nice red star (Aldebaran) which represents the eye of Taurus (The bull). \nLeft to Taurus, there´s a beautiful open cluster called The Pleyades (in the story, I think the brightest stars  represent seven sisters, but you´ll surely be able to count many more). \nIn the opposite side of the sky, you will find the Southern Cross (La cruz del sur). You can recognize it because of the four bright stars defining a clear cross. If you extrapolate the long axis of the cross four times toward where the cross is pointing, you´ll find the celestial northern pole: the point around which all the stars revolve during the night in the southern hemisphere. Besides, if you draw an imaginary line from that point in the sky to the ground, you´ll get South. An excellent way to get orientated in the field. To a side of the cross, you´ll see two bright stars: alpha and Beta Centauri. Alpha is the closest star to the Earth. \nMost of these features are more prominent during summer, but you can also see them in winter fro a brief period. \nAlso during winter, one of the best constellations is Scorpius, featuring Antares, the Red Giant. \n\nThat´s all I recall. \nIt´s a very interesting sky! Consult your charts to get the most out of it. \nHave fun!

Assuming you meant "solar system", yes. Officially, it is currently known as 2003 UB313, but it has unofficially been called "Xena", and has a moon, also informally known as "Gabrielle"\n\nIf you genuinely meant "Milky Way", there are 100,000,000,000 stars in the milky way, implying that there may be several hundreds of billions of planets in the galaxy.
