How far away is the nearest quasar?
Quasars are generally considered to be up to 10-12 billion light-years away. Despite being the brightest quasar visible from earth (and therefore the first to be discovered) EC-273 is not actually the closest to Earth. A quasar named PKS2349 is actually the closest, being around 1500 million light years away (1.5 billion) from earth.

A quas i-stell ar radio source, a quasar, is a very distant galactic nucleus that is extremely active as regards energy output. These sources just pour out electromagnetic energy in the form of light and radio waves. We also know that they are extremely far away because of the red shift associ…ated with our observations of them. They are among the most distant objects we know, and they are moving away from us at very high speed, which is what gives their light the red shift. There is more information available at the Wikipedia article on the quasar, and a link is provide to the post. You'll find it below. Answer Imagine a light as bright as the light from a hundred galaxies. The light is being generated by stars and other material which are being dragged into a super sized black hole. As the material is being dragged into the black hole it is subject to huge friction which heats it up to millions of degrees. This kind of super powerful black hole is a quasar: the most powerful kind of object in the universe. By the time their light reaches us, they have long, long since sucked the life out of the galaxy they were feeding from. A quasar will only exist in a really big galaxy... our galaxy, the milky way, isn't in any danger, because although we have a black hole at the centre of our galaxy; there is not enough matter to create the conditions for a quasar. Many years ago, when modern astronomy was still in its infancy, astronomers looked at all the lights in the sky and tried to figure out what they were. Some were stars, bright points of light, and some were smudgy, smeared objects; almost cloudy-looking. Those got the label "nebula", from the Latin word for "cloud". But it was difficult to determine how far away the objects were; the relative brightness was one of the few clues. Later on, Edwin Hubble realized that the universe is expanding, and that most of the other galaxies were receding from us. By measuring the red-shift of the stars or galaxies, astronomers were able to determine how fast the objects were going, and because of the nature of the expansion, had a new way of determining distances. There was one BIG problem. There were stars that appeared to be point-sources, so they weren't galaxies or nebulae, but were receding too quickly - and therefore too far away - for any star to be visible. There was just NO WAY for a star to be bright enough to be visible from that far away. From their distance and their brightness, they would need to pack the brightness of a galaxy into the size of a solar system, which was clearly beyond our (then) comprehension. Astronomers named them "Quasi-Stellar Objects", and because most people are too lazy to use three words when one will do, shortened it to "quasar". It took decades for some agreement to be reached on what the objects are that are so bright and yet so distant, but the current thinking is that a quasar is the accretion disk of gas and matter heated to incandescence by the gravity of a supermassive black hole in the center of what may have once been an "ordinary" galaxy.

Planet classification of this sort is only a Star Trek invention. It does not exist in science. "M-class" presumably denoted a planet suitable for earthlings....or Vulcans...or whatever. So the answer is....right here. ............. dude what he meant is simply what is the nearest planet that we k…now of.....aside from earth.... that may have a possibility of being m-class (by the term rich with water and in the "Goldilocks" zone) by what i have see in a recent set of documentaries they think the nearest planet like that may be 20 light years away... which in the scale of our galaxy inst really too far away XD (MORE)
I believe it is the Pleiades, Messier 45. The current best estimate at its distance is 135 parsecs, or about 440 light years away. Also as an interesting aside in Japanese it is known as Subaru and is used as the companies logo as seen on the front of its cars.
The nearest star (besides our sun) is 4.24 light-years from earth. This means that light emitted for this star takes 4.24 years to reach earth. Some stars are over millions of light-years away. The closest star is the sun. Beyond that is Proxima Centauri, at 4.24 light-years away. Alpha Centauri is …at 4.37 light-years, and beyond that is Barnard's star at 5.97 light-years away. 4.24 light-years = roughly 24,925,000,000,000 miles (rounded to the nearest billion miles) lol (MORE)
The Sun is at a distance of 8 light-minutes; about 150 million kilometers. The next known star (apart from our Sun) is Proxima Centauri, at a distance of 4.2 light-years. . See the Sources and related links below for a link to Wikipedia's list of nearest stars.
Quasars are: quasi-stellar radio sources. The consensus now is that: quasars (the most luminous objects in the Universe) are compacted regions in the middle of massive galaxies. Quasars owe their high energy to the accretion discs surrounding massive black holes at the center of these galaxies.
The Gulf of Mexico (part of the Atlantic) is about 400 miles from Southern Missouri.
A list of the top 10 closest stars is here:. http://space.about.com/od/stars/tp/closeststars.htm. The first closest is the sun..

There is a tie for third. Centauri A and Centauri B are 4.3 light-years away and are also in the Alpha Centauri system. (MORE)
Milky Way Galaxy - Our Galaxy . Omega Centauri - former galaxy - 0.0183 million light years away . Canis Major Dwarf - 0.025 million light years away . Virgo Stellar Stream - 0.03 million light years away . Sagittarius Dwarf Elliptical Galaxy - 0.81 million light years away . Large Magellanic C…loud - 0.163 million light years away . Andromeda Galaxy - Largest - 2.5 million miles away. The Canis Major Dwarf Galaxy orbits the Milky Way at 42,000 light years from the galactic center. The Sagittarius Dwarf Elliptical Galaxy orbits at 50,000 light years. The Large and Small Magellanic Clouds are also very close to the Milky Way, but there is some debate over whether they are "orbiting" the larger galaxy. However, orbiting or not, they are still considered "satellites" of the Milky Way. All of these galaxies are very small compared to the Milky Way and most are irregular in shape, all of them lacking the spiral structure normally associated with a well-organized galaxy. The Phoenix Dwarf Galaxy is 1.44 million light years from the center of the Milky Way, and NGC 6822 (aka Barnard's Galaxy) is 1.6 million light years away. See related link for more information.

If the Sun was 1 ft across instead of 865,000 miles, the neareststar would be about 5500 miles away.
12.5 light years away :) 73487500000000 miles 118259130907260 kilometers that is the nearest galaxy but the nearest sun is Alpha centauri; it is 44000 Billion km away from earth
Between approximately 4 and 6.5 AU, depending on the relative positions of Earth, Jupiter and Sun.
It's about 93 million miles or 149.6 million kilometers. That's an average distance because the Earth's orbit is not perfectly circular.
The Sun: 150 million kilometers. This distance is also known as 1 astronomical unit. After the Sun the nearest known star is Proxima Centauri, at a distance of 4.2 light-years.
The nearest solar system to ours is called "Alpha Centauri System" and can only be viewed from the southern sky and is estimated to be 4.4 light years away. Please see related link below!
the quasar distance can reach up to 13 billion light years away to 16 billion light years away.
It is difficult to assign values to the distances to quasars, because they are so bright and massive; the only way to measure this is to use the Hubble Doppler effect. However, high gravity can affect that, and we don't know how massive the objects are. Based on that, the most distant quasars are… about 10 billion light years away - or, back 2/3 of the way to the Big Bang. (MORE)
From the peak of the mountain or from the base of the foothills?, and are you asking about the center of town, or the city limits, or the outer fringes of the suburbs? You need to be a little more specific, and... There's something else,.... Oh! right. What capital? What mountain?
Venus is the nearest planet to Earth. The distance between Venus and Earth varies from 38 million kilometres (23.7 million miles) at it's closest point to 261 million kilometres (162 million miles) at it's most distant (when it is behind the Sun).
The same distance as Earth's nearest star - roughly 90 million miles; it is the Sun.\n. \n. \nSince the Moon is in the same relative position as earth (separated by only 1.2 light SECONDS) it would be Proxima Centauri at 4.2 light Years.\n. \nEDIT: looks like I fail since it is the Sun and not Pr…oxima Centaur. Was this a trick question or did the OP really not understand just how close the Earth and Moon are relative to each other? (MORE)
More than 200,000 quasars are known, most from the Sloan Digital Sky Survey. All observed quasar spectra have redshifts between 0.06 and 6.5. Applying Hubble's law to these redshifts, it can be shown that they are between 780 million and 28 billion light-years away.
Quasars, or "quasi-stellar objects", are star-like things that are incredibly far away and impossibly bright; far TOO bright to actually be stars. Scientists have no good data on the size of quasars, but they are likely to be much larger than ordinary stars.
It's approximately 4 light years to Proxima Centauri, a red dwarf in the Alpha Centauri system.
There are few songs named 'Far Far Away'. The best known is famous Slade's Far Far Away. Both a single aswell as a soundtrack to the film Slade in Flame with this songappeared in 1974. The original title of the Slade song Far Far Away was (supposedly)'Letting Loose Around the World' (a part of the… lyrics of thesong). 'Far Far Away' is also a song By Blackmore's Night (2008) and asong by Wilco is named 'Far, Far Away' (1996). (MORE)

If you find a place where the sky is good and dark and you know where to look, you can see the Andromeda Galaxy in the night sky. It looks like a fuzzy patch of dim, hazy light. It's actually a galaxy of hundreds of billions of stars, completely outside of the Milky Way galaxy that we live in. The …distance to the Andromeda Galaxy is usually given as a couple of million light years. That would be the answer to the above question. (MORE)

Quasars emit enormous amounts of radiation, more than anything elsein the universe. This radiation carries enough momentum to pushstars and gas clouds away from the black hole. Things can escapethe gravity of a black hole so long as they do not cross the eventhorizon.
The nearest Greyhound station is on 36 Hunter St E, which is a distance of 0.77 miles (2 minutes) away from 118 Market Street.
light travels 186000 miles per second, multiply by 60, then 24 to get miles per day. Multiply THAT by 365.25 for a year. That is a Light Year, expressed in miles. Multiply by 4.2, then DIVIDE by 0.62 to express your answer in km.
You are still exactly where you are. The words "how far away are you" require a reference to the Place you are far away from. Are you just being "cute" and actually mean the first part of the sentence to be the answer to the second part? If this is so, then why ask the question since this website is… for those who have legitimate questions and don't already know the answer? Could it be that you forgot to put in a reference? Don't know, but this question is hard to take seriously. Perhaps you could rephrase it? (MORE)
the nearest galaxy from ours is the Andromeda (an-DRO-mu-duh) galaxy, an irregular galaxy. it is about 30,000,000 (30 million) miles away. There are other irregular galaxies scattered around it, which are about a lightyear (60 million mi) away.
All observed quasars have redshifts between 0.06 and 6.5. Using Hubble's law, it can be shown that they are between 780 million and 28 billion light years away (in terms of comoving distance). See related link for more information.
That is a good question - astronomers are actively pursuing an answer. So the only answer is: no one knows.
The nearest (major) seaports to Arizona are in San Diego, Los Angeles and Long Beach (the last two are pretty much the same port). These ports are 360-400 miles away from the center of Arizona.
Nice question, it really shows how far some of these objects are from us. 3C 273 is a Quasar located in the constellation of Virgo.

Are quasars moving away from us at the speed of light since from the big bang as they are 13 point 7 light years away?
The farthest known galaxies / quasars are at a distance of over 40 billion light-years, and are moving away from us faster than the speed of light. Locally, nothing can go faster than the speed of light, and in their "own space", they don't. But in this case, it is "space itself" that is expanding. …The Wikipedia article on "metric expansion of the Universe" gives a more detailed explanation on this topic. (MORE)

If you live in a large town, you most likely live within fifteen miles of a store. If not, then add the distance to the nearest town to those fifteen miles and you will have an approximate answer.
Quasars can be very, very, very far away. And they are extremely bright. We've seen quasars that are 12 billion light years away from Earth (a light year is how far light travels in one year, and light travels at about 128 billion kilometers a second). Most quasars are actually big, bright galaxies …shining from millions, or even billions of light years away from here. (MORE)
