How many stars are there in the constellation of Hydra, the largest in the sky?
354596
There were only 2 stars (if magnitude < 3)
445045
Nearest star -- Proxima Centauri (or Alpha Centauri C) is 4.22 light-years away \nFarthest star -- Unknown. There are other galaxies as far as 13.7-billion light years away with stars, but we can't measure their individual distances\nFirst discovered -- Unknown. Who or whatever animal first looked up at the night sky and saw a star untold millions of years ago

with an apparent magnitude of -1.4, Sirius (or Alpha Canis Major) is the brightest star not only in the winter sky, but in all of the sky.  it can be found by following Orion's belt down and to the left.  if you go up and to the right along Orion's belt, you encounter Aldebaran, the brightest star in Taurus the Bull.\n\nSirius is about 8 light years away, and is a triple body system.  There is Sirius, the A0 star that is quite visible, a white dwarf (visible only in very large telescopes), and another dark, dead companion whose effects are only visible by how its gravity affects Sirius and the white dwarf.

The link in the first answer doesn't work.\n\nOnly some of the stars in this constellation have names: \nAlrisha (Alpha Psc), aka Alrescha [Al Rescha, Rescha, El Rischa, Al Richa] or Kaitain or Okda (= the ropes).\nOkda (= Knot) \nFum al Samakah (Beta Psc)(=Mouth of the fish) \nTorcularis Septentrionalis (Omicron Psc) (=Of the northern wine/oil press)\nAlpherg or Kullat-Nunu \nvan Maanen's star

this is kind of a trick question as it depends on who you ask and what you mean by largest\n\ngenerally hydra is considered the largest, as it is the longest and streches the length of 172 full moons placed side by side.\n\nbut it is in the southern hemisphere so many people in the northern hemisphere (mostly americans) don't know about it and say that orion is the largest.\n\nand orion is the largest constelllation in the northern hemisphere.\n\nnow if by largest you mean distance and not just area of the sky well then that is different again.\n\nbut just go with hyda, that is what I do.

It's my understanding that we don't belong to a constellation, but a galaxy. This would be the Milky Way galaxy. Constellations refer to the divisions of the sky from the earth. The zodiacs are constellations, Virgo, Gemini, Taurus.

Which constellations are circumpolar depends on your latitude.  The five closest to the pole are Ursa Minor (female bear cub in Greco-Roman myth), Draco (dragon), Camelopardalis (a giraffe, a constellation invented by Kepler's son-in-law, Bartsch, and hence lacking any ancient myth), Cepheus (a king, husband to Cassiopeia and father to Andromeda), and Cassiopeia.  I suggest you ignore the first 3 and go with the old stand by of Andromeda being sacrificed to pacify a sea monster and rescued by Perseus, unless you are supposed to invent your own myth, based on these 5.

Brad is right; there are around 3000 stars visible to the naked eye at a given moment under good seeing conditions. There are around 8000 visible in the whole 4pi sky.\n\nOur galaxy, the Milky Way, contains about 10^11 (100 billion) stars. There are about 10^11 galaxies, so about 10^22 stars in the whole 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!

Largest Star (By Size) - VV Cephei - 1900 times diameter of sun\n\nMost Luminous Star - LBV 1806-20 - 40,000,000 times luminous than the sun\n\nHowever, the brightest objects in our universe are the quasars... Check the links below for more info\n\nI hope these were the answers u were lookin for...

The Latin named constellations were named by Claudius Ptolemy, Greek-speaking mathematician, geographer, astronomer, and astrologer. He lived c. 90 – c. 168 AD in the Roman Empire and was almost certainly a Roman citizen with a name like Claudius.\n\nPtolemy's list of 48 constellations includes Canis Minor, which means "small dog" in Latin. It is said to represent one of the dogs following Orion the hunter.\n\nCanis Minor is a small constellation mainly consisting of the two stars, Procyon and Gomeisa . Procyon is the eighth brightest star in the night sky. Procyon means "anterior dog" in Greek, as it rises before the Dog Star, Sirius, of Canis Major. Due to the brightness of Procyon, this was likely target for Ptolemy to create a constellation.\n\nHope this helps!

There are a lot of red stars in space. From Nasa's web site: "There are many normal red stars near the Sun, with temperatures of a few thousand degrees and masses much less than that of the Sun. None, however, is bright enough to be seen without a telescope. All of the bright red stars in the night sky are red giants and supergiants, counted among those we term abnormal stars. Examples are the supergiants Betelgeuse in Orion and Antares in Scorpius (each about 520 light years from Earth) and giant Aldebaran (68 light years) in Taurus."

First find the Big Dipper constellation (Ursa Major) Find the two stars farthest from the dipper handle. Draw an imaginary line from the bottom star through the top star and extend the line outward. The first bright star your imaginary line comes near is the North Star---that's north.\n\nThe website shown has a diagram of the above.
