What does the 3 stars with equal distance in the sky mean?

Yes, this is terribly significant for your date of birth. They are known as "the small boring group of faint stars" acording to ancient Persian astrological tradition.\n\nPeople born under this sign are all much less interesting and talented than other people. Most are either Eskimos or axe murderers. They have strong tendency to be born, do a bunch of stuff and then die.

How many stars are there in the sky?\n\nSeriously, I don't know if there's a number you could get that would be accurate.  Between banks, credit unions, grocery stores (mine actually has its own), plus the countless independently-owned ATM's at gas stations and convenience stores, you are deep into the millions for sure.

It looks like it could be taken from Latin \n(1) ardua + astra ("lofty" or "difficult to reach" + "stars" or "heaven" {reminiscent of the motto per ardua ad astra} \n\nor (2) from ardere + astra ( "to blaze" + "stars")\n\nSo it could mean "blazing stars" or "lofty stars" unless the word is derived from something unrelated to Latin.

Magnitude is a logarithmic scale and negative numbers are brighter than positive numbers.  Hence a magnitude 1 star is ten times brighter than a magnitude 2 star and 100 times brighter than a magnitude 3 star.  A magnitude 0 star is 10 times brighter than a magnitude 1 star and a magnitude -1 star is ten times brighter than a mag 0 star.\nAldebaran is simply a lot brighter (bigger and hotter) than formalhut, despite being much further away.  If the two stars were at the same distance, i.e. you're talking about relative magnitude, aldebaran would have a much lower rel. magnitude than formalhut and therefore appear much brighter.  Are you confused enough yet?\nThink of relative magnitude (also known as absolute magnitude i think) as the magnitude the star would have if it was 10 times further from us than the sun is- that enables the astronomers to compare like with like.\nParallax is the angle through which the star appears to move against the background of 'fixed' stars.  As the Earth moves around the sun, our perspective of the universe changes.  Nearer stars appear to move relative to the ones that are furthest away.  Hence, Formalhut, a nearby star, appears to move through a greater parallax angle than distant Aldebaran, which is fairly fixed against the stellar background.

There is a surprisingly simple answer to your great question: Each month we see different stars, so to answer for a specific night of the year at your specific location on Earth depending on your eyesight and how bright the city lights around you are might be hard to pin down. \n However there is a magnitude scale that astronomers use to describe how bright objects in the sky are. Without getting into details on how that works, the average human being can see down to about magnitude 6 ( brighter objects have lower magnitude until you reach zero. Then even brighter objects use negative numbers for their magnitudes which is a bit weird, isn't it?) Therefore, all you have to do is get a map of the whole sky showing anything brighter than magnitude 6 and count the stars. If you are fortunate to be away from bright city lights and you can see the Milky Way, you would be really surprised to know that you can only see about 6,000 stars. That's the number of stars above magnitude 6 in the entire sky.

It is equal to about 3.26 light years. Parsec stands for "PARallax of one arc SECond". It is extensively used in measuring astronomical distances.\n\nIt is based on the method of trigonometric parallax, one of the most ancient and standard methods of determining stellar distances. The angle subtended at a star by the mean radius of the Earth's orbit, around the Sun, is called the parallax. The parsec is defined to be the distance from the Earth of a star that has a parallax of 1 arcsecond. Alternatively, the parsec is the distance at which two objects, separated by 1 astronomical unit, appear to be separated by an angle of 1 arcsecond.\n\nSee: http://en.wikipedia.org/wiki/Parsec

well stars are in real more like our sun which gives heat and light, but y they have diff color id coz AS ALL THE STARS ARE NOT AT THE SAME DISTANCE FRM THE EARTH THE LIGHT WHICH TRAVELLS FRM THEM AND REACHES US GIVE THEm COLOR .\n\nLIKE white light has 7 colors in it and each has different wave lenght which means that their light travels on those wave lenghts, and secondly the air in our atmosphere water particles are suspended always and these light passing through them give different wave lenght wch gives us diff color

It sounds like you need three things\n\nA starting point for each star.\n\nA vector for each star (that takes care of direction and speed)\n\nGravity (The more dense a star is in relation too its mass the greater its gravitational pull)\n\nOnce you have worked out the specific gravity for each object (star) the only things that vary are the vector of each star and thus its new position.\n\nGood luck!! I know any gravitational calculation with three or more object gets very complicated very quickly.

OMG, definitely...when was the last time you looked at the sky?  Sun, stars, rainbows, moon.  Relax and begin to enjoy the things that are truly free.  Dont agree on the subjects of friendship, love, etc.  They are usually outrageously priced in the emotional category.

sun....its a star btw but there are stars bigger than the sun

The greater than symbol and number three side by side (<3) stand for love and/or friendship.  Tilt your head to the side and you should be able to see that it makes a heart shape.

All stars are round, and there are many trillions of stars, although you can only see about 3,000 of them at any one time without a telescope. The sun is a typical star, only much closer than all the others.

when the light from the stars enter the earth's atmosphere, the light wave bends and refracted until it reach our eyes. So because it is refracted, when we look at it, it seems to be twinkling.

Up in the sky somewhere, at a guess.

Not a simple question, but  this is two main reasons.\n\n1) Brightness of the Star Play a part.   Assume uniform Atmosphere.\n\n2) The Atmosphere also another part.  Assume stars of the same brightness.\n\n1)  Brightness of the Star Play a part.\nBrighter the Star, less likely the twinkle.   Look at the Moon, does it go Bink Bink?  Too Bright.\n\nBut Dimer stars, under the same Atmospheric conditions, may Bink.\n\n2) The Atmosphere also another part.\nThe Atmosphere is not uniform, look at the sky during the day, sometime, it clear blue,  and other time clouds mass abound.\n\nThe Atmosphere is like a thin soup, with some sliver of bread in it,.  using that example, when the Stars of the same brightness is in the Sky,  imagine when a sliver of bread blocks lightly one of the stars, thus one Bink, and another don't.\n\nIt Real life, Stars are not of the same brightness, and the Atmosphere is not always uniform.  making the issue complex.

The distances to stars closer than about 150 light years can be measured directly by use of parallax.  The position of the star against background stars is measured at times 1/2 year apart, and then it is a simple mathematical procedure to determine the distance (you have a side and two angles of a triangle--the angular distance the star appears to move at it's distance over 1/2 year equals 186 million miles-the diameter of the orbit of the earth).  \n\nStars farther than that cannot be measured directly.  But, by use of knowledge about how bright a star should be (on average) for it's spectral type (which loosely is governed by its mass) an estimate of its intrinsic brightness can be made, and then by looking at how bright it appears, it's distance can be estimated.\n\nCepheid variables are used, as well, but mostly to determine the distances to groups of stars and of other galaxies.  Incidentally, the North Star (Polaris, or Alpha Ursa Minor) is a cepheid variable.\n\nNovae and supernovae tend to have average intrinsic brightnesses, so their apparent brightness in, say, a distant galaxy, tells us (within limits) it's distance.\n\nRed shift is used for objects outside our galaxy because the amount of red shift within our galaxy would be extremely small (it increases with distance) if it were not totally overcome by the gravity of the galaxy.

Sounds like you may be looking at Sirius, the brightest star in the  sky. It is a blue star but because of the refraction of the Earth's atmosphere appears to flash red every few seconds. It doesn't matter where you  are. It's visible this time of year anywhere in the northern hemisphere. BTW Sirius is called the dog star because it is part of the constellation Canis Major, the big dog. Canis Major looks just like a stick drawing of a dog and Sirius is its eye.
