It is called a QUAsi-StellAR Object or quasar.\n\nNowadays they are generally believed to be galactic cores with enormous black holes at their center.\n\nIt appears starlike (quasi-stellar) but is actually very different in size and what it's made of.

In lay man's terms:\n\nA star: a huge ball of fire, emitting heat and light, mostly composed of gasses and the source of the heat is the nuclear reactions happening isnide it due to the massive pressure in its core. An example is the sun, the temperture of its surface if more than 5000 degress centigrade, while the temperature of its core is several million degrees. A star is 'usualy' much larger than planets(thouthands to millions of times larger) . Some stars have planets orbiting around them (e,g, our sun)\n\nPlanets: Intert masses that do not emit light or radiate heat. Planets revolve around stars and are far much smaller than stars(e.g. earth, mars, saturn, jupiter,etc). Some planets have moons(much smaller planets) revolving around them.Mostly planets are solid masses, but sometimes they are made of gases. The temperature of planets is far cooler than stars.

Stars, except for the Sun, although they may be millions of miles in diameter, are very far away.  They appear as point sources even when viewed by telescopes.  The planets in our solar system, much smaller than stars, are closer and can be resolved as disks with a little bit of magnification (field binoculars, for example).\n\nSince the Earth's atmosphere is turbulent, all images viewed up through it tend to "swim."  The result of this is that sometimes a single point in object space gets mapped to two or more points in image space, and also sometimes a single point in object space does not get mapped into any point in image space.  When a star's single point in object space fails to map to at least one point in image space, the star seems to disappear temporarily.  This does not mean the star's light is lost for that moment.  It just means that it didn't get to your eye, it went somewhere else.\n\nSince planets represent several points in object space, it is highly likely that one or more points in the planet's object space get mapped to a points in image space, and the planet's image never winks out.  Each individual ray is twinkling away as badly as any star, but when all of those individual rays are viewed together, the next effect is averaged out to something considerably steadier.\n\nThe result is that stars tend to twinkle, and planets do not.  Other extended objects in space, even very far ones like nebulae, do not twinkle if they are sufficiently large that they have non-zero apparent diameter when viewed from the Earth.

No. \n\nStar:\nA self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures\n\nPlanet:\nA nonluminous celestial body larger than an asteroid or comet, illuminated by light from a star, such as the sun, around which it revolves.\n\nSo, stars are self-luminous (have their own light) and are stationary. Planets don't produce their own light and revolve around a star.

Yes, almot every star we see is a star from this galaxy. Their are also other galaxies, but we see those only as other points of light, since they are so far away, and five planets that usually glow brighter than the rest of the lights. Also tthe brighter part of the galaxy is just a denser cluster of stars, and we do see it, it's the milky white band we see at night from horizon to horizon, it's called the Milky Way.

It's name is Polaris and is the brightest star in the Ursa Minor constellation. This can help you more: \nhttp://en.wikipedia.org/wiki/Polaris

there are several (you did not provide enough details)...could be a sun, galaxy, nebula, etc.

Hi. A good one might be Regulus because it lies pretty close to the ecliptic and is very bright. But you can use any star. For much better accuracy scientists use quasars due to their vast distance. This eliminates parallax error.

Bigger that what? \n\nRemember, these planets are still a long ways away. \n\nAnd the morning star/evening star, which is Venus, sometimes called Lucifer or Hesperides or Phosphorus or Hesperus (The identification of morning star with evening star, or Phosphorus=Hesperus was famously realized by Pythagoras) is very large and bright in the sky sometimes. \n\nMercury is a bit harder to see because it is so small, and so close to the sun.

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

STARS AND NEBULAE.\n\nMost of the things you can see in the night sky are stars: a few thousand are visible to the unaided eye. A star is a hot ball of mostly hydrogen gas; the Sun is an example of a typical, ordinary star. Gravity keeps the gas from evaporating into space, and pressure due to the star's high temperature and density keeps the ball from shrinking. In the core of the star, the temperature and densities are high enough to sustain nuclear fusion reactions, and the energy produced by these reactions works its way to the surface and radiates into space as heat and light. When the fuel for the fusion reactions is depleted, the structure of the star changes. The process of building up heavier elements from lighter ones by nuclear reactions, and adjusting the internal structure to balance gravity and pressure, is called stellar evolution. \nLooking at a star through a telescope can tell us many of its important properties. The color of a star tells us its temperature, and the temperature depends on some combination of the star's mass and evolutionary phase. Usually, observations also allow us to find the luminosity of the star, or the rate at which it radiates energy as heat and light. \nAll stars visible to the unaided eye are in our galaxy, the Milky Way. The Milky Way is system of roughly 100 billion stars, along with a great deal of interstellar material. The galaxy is shaped like a flattened disk embedded in a round, faint halo. Gravity keeps the stars from drifting away, and the motions of the stars keep the system from falling in on itself. The Milky Way has no distinct edge - the distribution of stars tapers off gradually with increasing distance from the center. The SDSS detects stars more than a million times fainter than can be seen with the unaided eye, far enough to see the outer structure of the Milky Way. \nStar Colors and Luminosities: The H-R Diagram\nAstronomers often make plots of the luminosities of stars compared to their colors. The first such charts were made in the early twentieth century, when astronomers took spectra of thousands of stars, then placed the spectra into a sequence based on the appearance of several different features. The classes of stars were given different letters as names; in order of decreasing temperature, they are OBAFGKMLT. The hottest stars are class O, while the coolest are class T. Two astronomers, Ejnar Hertzsprung and Henry Norris Russell, independently started to wonder what would happen if they compared stars' luminosities to their spectral classifications (or, alternatively, to their temperatures). They knew that some stars were hotter and more luminous than the sun, and that others were cooler and less luminous. Hertzsprung and Russell found that 90% of the stars fell into a narrow band they termed the "main sequence." Today, we call this type of plot a Hertzsprung-Russell (or H-R) diagram. \nAstronomers further divide each letter into ten categories from 0 to 9, with 0 being the hottest star in that spectral class and 9 being the coolest. So, a B1 star is hotter than a B2 star, and a B9 star is hotter than an A0 star. Our own sun is at the "hot" end of the G range with a surface temperature of 5,770° K; therefore, it's called a G2 star. \nSpectral classes give us a convenient way to refer to most types of stars - from O0, the hottest at over 25,000° K, down to T9, the coolest failed stars at 1,000° K. Each spectral type of star is associated with a specific color: all G-type stars like the sun are yellow, all M-type stars appear red, and all B-type stars are bluish. Thus, this system of letters and numbers tells us where a star is on the horizontal (color or temperature) axis of the H-R diagram. \nTwo alternative systems tell us approximately where on the vertical (luminosity) axis a star can be found. One system uses absolute magnitude, a measure of luminosity derived from the apparent magnitude, or brightness of the star

The brightest stars, the ones you can see with the naked eye, are all B8 and B9.  Some of the dimmer ones are of other classes--B,A,F, and perhaps some cooler classes, too.

The brightest star as seen from the Earth is Sirius, not the sun, whose scientific name is Helios, nor the North Star, whose name is Polaris.  Sirius is located in the constellation Canis Major.  It is also known as the Dog Star.\n\nhttp://en.wikipedia.org/wiki/Sirius

Its actually not a star at all. Its the 2nd planet from our sun, Venus.\n\nYou can see it in the early morning as well.

The burned out centre of a low mass star is a white dwarf. It's a hot ball of carbon and oxygen, though too cool for thermonuclear reactions to occur. They're about the size of Earth and are too dim to be seen with the naked eye.
