Alpha Centauri is the brightest star in the constellation Centaurus and 3d-brightest star in the sky; also known as Rigil Kent or Rigil Kentaurus; 1992 position R.A. 14h39.1m, Dec. −60°49′. It is a yellow main-sequence star of the same spectral class (G2 V) as the sun and of about the same size and mass; its apparent magnitude is −0.26. Actually, Alpha Centauri is a triple-star system, the components being designated A, B, and C. Alpha Centauri C is also called Proxima Centauri because it is the closest star to the earth (other than the sun), at a distance of 4.28 light-years, components A and B are currently 4.34 light-years away. Proxima Centauri orbits about the common center of mass of the system with a period of more than 250,000 years, so that in about 125,000 years it will be more distant than A and B.\nThis is not counting the sun, friend.

The general term is double star. If the two stars are actually physically close so that they orbit each other, it is also called a binary star. Stars that appear close together but are actually at very different distances are called optical doubles.

This website shows relative distances from the sun. You can then calculate their distances from each other by using (Farther planet's distance)-(closer planet's distance).\n\nhttp://www.idahoptv.org/ntti/nttilessons/lessons2000/lau4.html

Alpha Centauri is only 4.3 light years away. Sirius is 8.6, Both are binary stars, two stars in a star system.

The distance that the moon is from the earth depends on the location of the moon during the lunar calendar.\n\nWhen it is closest to the earth, the moon is 363,300 km from the earth (roughly 225,744.154 miles, 1.19192913 × 109 feet)\nWhen the moon is the farthest away, it is 405,500 km from the earth (roughly 251,966.018 miles, 1.33038058 × 10^9 feet)\nOn average, the distance from the earth to the moon is 384,400 km (roughly 238,855.086 miles, 1.26115486 × 10^9 feet)\n\nMeasurements reveal that the Moon's distance to the Earth increases by 38 mm per year!

Scientists recently discovered a (presumed) rocky planet orbiting a small red-dwarf star about 25,000 light years from Earth.  The planet is about 5 times larger in diameter than Earth and revolves around its sun about two and a half times further away than does earth.  Because its sun is smaller and cooler and because it rotates further away than does Earth, the average temperature is about -300 degrees and so probably does not harbor life.

Proxima Centauri is a puny whimper of a star, a red dwarf (spectral type M5.5 V). It is gravitationally bound to Alpha Centauri, a double star system. It consists of Alpha Centauri A and Alpha Centauri B. A and B are stars very much like the sun (spectral type G2 V and K0 V) except they orbit around a common center of gravity. Although being the closest star to earth Proxima is so faint it can only be seen with a telescope (from the southern hemisphere to boot). Not even Alpha Centauri, despite being TWO stars, is the brightest star in the night sky. But what Proxima misses out in brightness it makes up for in longevity. The sun, you may know, is in it´s main sequence right now and it will remain there for atleast a few billion years more. That may seem like a long time but proxima will remain on the main sequence for a TRILLION years!

All stars except the Sun appear to the human eye as shining points in the night sky that twinkle because of the effect of the Earth's atmosphere. Interferometer telescopes are required in order to produce images of these objects. The Sun is also a star, but it is close enough to Earth to appear as a disk instead, and to provide daylight.\n\nStars are not spread uniformly across the universe, but are typically grouped into galaxies. A typical galaxy contains hundreds of billions of stars. The majority of stars are gravitationally bound to other stars, forming binary stars. Larger groups called star clusters also exist.\n\nAstronomers estimate that there are at least 70 sextillion (7×1022) stars in the known universe [1]. That is 70 000 000 000 000 000 000 000, or 230 billion times as many as the 300 billion in our own Milky Way.\n\nThe nearest star to the Earth, apart from the Sun, is Proxima Centauri, which is 39.9 trillion kilometers, or 4.2 light years away (light from Proxima Centauri takes 4.2 years to reach Earth). Travelling at the orbit speed of the Space Shuttle (5 miles per second -- almost 30,000 kilometers per hour), it would take about 150,000 years to get there. Distances like this are typical inside galactic discs, where the Sun and Earth are located. Stars can be much closer to each other in the centres of galaxies and globular clusters, or much further apart in galactic halos.\n\nCheck the wikipedia link below.

Yes, it is. It is the third closest star to The Sun (Sol) after Proxima Cenaturi and Barnard's Star. "A very cool, main sequence red dwarf (M5.8Ve), Wolf 359 is our Sun's dimmest stellar neighbor within 10 ly, with less than 2/100,000th of Sol's luminosity." It is 7.8 light years aways and is in the constellation Leo.

Well, within 1 lightyear of earth there isn't anything we know of. The nearest Star is Alpha Proxima (or is Centauri B closer now?) and its around 4.5 light years away.\n\nThere are around 100 stars within 50 lightyears of earth and that number grows as you move away. You wont find any other clusters or galaxies until you get to around 2.5 million light years with the closest Galaxy, Andromeda. - the nearest supercluster is more on the order of 50 million light years.

Mercury, Venus and Mars are always closer than 574,380,430.5648 miles.  That number is close to the distance of Jupiter at it's farthest.

The new planet is the most distant object ever seen in orbit around the sun, even more distant than Sedna, the planetoid discovered almost 2 years ago. It is almost 10 billion miles from the sun and more than 3 times more distant than the next closest planet, Pluto and takes more than twice as long to orbit the sun as Pluto.

Parallax is the method that uses triangulation. The diameter of the earth's orbit around the sun is 186,000,000 miles. A "nearby" star can be observed twice six months apart, and it will seem to have moved against the background of "distant" stars. Trigonometry can then be used to estimate the distance to the nearby star. \n\nThe particular months of observation depend on the location of the star. First, you have to know in which month the star appears due south at midnight ("in opposition"). Then you make your two observations three months before and three months after. Of course, you have to wait until the following year to make your "three months earlier" observation.\n\nYou can see the parallax effect in your front yard. Stand in your front yard so that a telephone pole on your side of the street is slightly to the right of a telephone pole across the street. Now move to the right. The nearby pole will move to the left of the distant one.

The red dwarf star Proxima Centauri, part of the Alpha Centauri star system, is the nearest star to the Sun. As the name suggests, it is located in the constellation of Centaurus. Proxima Centauri was discovered in 1915 by Robert Innes while he was Director of the Union Observatory in Johannesburg, South Africa.\n\nProxima Centauri is roughly 4.22 light years from Earth, or 270,000 times more distant than the Sun.
