The Alpha Centauri system is estimated to be at a distance of roughly 4.4 light-years from our solar system.
At 9.46089 x 1012 km per light year, that multiplies out to 4.1627916 x 1013 km, or 41,627,916,000,000kilometers.

About 41.5 trillion miles.
Since Jupiter orbits our sun, the average distance between Jupiter and Alpha Centauri will be about the same as the average distance between our sun and Alpha Centauri--the next nearest star system.

Is Alpha Proxima the same star as Proxima Centauri?
To my understanding, the Alpha Centauri system contains two binary stars (Alpha Centauri A and Alpha Centauri B) and a third star Alpha Centauri C or Proxima Centauri (which is the closest star to our sun)
How old is Alpha Centauri compared to the Sun?
The Heliopause is at a distance of appx 120 AU from the Sun. That is around 0.0019 light years. Te Alpha Centauri star system is 4.365 light years away from the Sun, and almost the same distance away from the Heliopause.
How does distance between earth and sun compare to distance between earth and nearby stars and galaxies?
We measure distances between celestial objects (such as suns, planets, and galaxies) by a unit of measurement called "AU" which stands for, Astronomical Unit. One AU is the equivalent to 93 million miles, which is roughly the distance from earth to the sun. Let's compare that to the next closest star to us, Alpha Centauri, which is 4.4 light years away, or about 271,930 AUs! Distances are Immense.
Are stars farther from Earth than the planet Saturn?
All stars other than our own Sun are MUCH farther from the Earth than the planet Saturn. Saturn is about 1.3 billion kilometers from Earth, whereas the nearest star is over 40 trillionkilometers, about 30,000 times as far!Our solar system extends to about 55 AU (8 billion kilometers) from the Sun, or about 1/50 of 1% of the distance to Alpha Centauri.
Why is he sun brighter than other stars?
The sun appears brighter because it is far closer. On average, the sun is about 93 million miles or 1 AU from Earth. The next nearest star is Proxima Centauri which is 4.2 light years or about 257,000 AU away.
What two stars have the same temperature?
No one knows for sure, but one possible candidate is the Alpha Centauri system, where Alpha Centauri A and Alpha Centauri B orbit each other at a distance of only 11.2 Au which is the equivalence of our Sun to Saturn.
Is Alpha Proxima the same star as Proxima Centauri?
To my understanding, the Alpha Centauri system contains two binary stars (Alpha Centauri A and Alpha Centauri B) and a third star Alpha Centauri C or Proxima Centauri (which is the closest star to our sun)
What is farther from Earth Alpha centauri or the sun?
That's actually an easy calculation, if you state the problem correctly. Alpha Centauri is about 4.5 light years away. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those numbers together to find out how many light-seconds it is to Alpha Centauri. The Moon is about 1.5 light seconds away, so divide by that to get the ratio.
Is How far is Alpha Centauri from Earth and How far is Alpha Centauri from the Sun the same question?
NO IT ISN'T. People have said is is but the distance between the Earth and our Sun is 1 AU which stands for Astronomical Unit which is 150 000 000 km so the distances must be different!Answer:1. The Earth is going round the Sun so twice a year the distance is exactly the same.2. The distance to Alpha C. is 276000 astronomical units therefore plus or minus 1 makes virtually no difference.
How old is Alpha Centauri compared to the Sun?
The Heliopause is at a distance of appx 120 AU from the Sun. That is around 0.0019 light years. Te Alpha Centauri star system is 4.365 light years away from the Sun, and almost the same distance away from the Heliopause.
The distance between your solar system and the closet one?
The nearest star to the Sun is currently Proxima Centauri. It is a distance of about 4.22 light years from the Sun.It is very likely that Proxima Centauri is gravitationally associated with the two stars of Alpha Centauri system since the separation is only 0.21 ly about 15,000 AU but no evidence of an elliptical orbit associated with a binary star has not been found. If this is correct then eventually Alpha Centauri A & B will become the nearest stars to Earth at a distance of 4.36 ly.

What in AU's is the star Alpha Centauri's habitable zone?
The [related links] contain all the information you want. Habitable zones for each of the major stars in AUs.You could perhaps try calculating the limits of the Habitable zones for each of the stars in the Alpha Centauri system yourself, using the 'Habitable Zone Calculator,' which is based on findings from an up-to-date research paper.Using the calculator and taking temperature/luminosity values given in Wikipedia, these were the limits I got for Alpha Centauri A, B and Proxima for the minimum inner edge of the habitable zone (Runaway Greenhouse limit, 1 Earth mass, 1 atmosphere):1.2 AU, 0.71 AU, 0.044 AUAgain using the calculator, the limits I got for alpha Centauri A, B and Proxima for the maximum outer edge of the habitable zone (1 Earth mass, 8 carbon dioxide atmospheres) were:2.1 AU, 1.2 AU, 0.09 AUA more conservative measure of the maximum outer edge of the habitable zone, the '1st Condensation Limit', the distance from the star where the average temperature of the planet is cold enough for the carbon dioxide gas in the atmosphere to freeze out, is not a scenario included in the calculator. This is because the paper the calculator is based on assumes that after carbon dioxide freezes out and the planet glaciates there would be an inevitable build up of carbon dioxide; rocks deep under an increasingly glaciated planet would no longer be reacting with the atmosphere and so would not be removing carbon dioxide which is being pumped out all the time into the atmosphere from volcanoes, resulting in a warming feedback. However, a rough estimate of the 1st Condensation Limit for a 1 atmosphere planet around Alpha Centauri A, B and Proxima would be:1.65 AU, 1.0 AU, 0.07 AUIt's a shame the 'Habitable Zone Calculator' is so buggy and that the site that hosts the calculator doesn't offer an Excel version to download and work from.

What star is the closest to us in the milky way?
The Sun is "really" the closest star at 150,000,000 km (93,000,000 miles)Proxima Centauri is the closest star to us, at a distance of approximately 4.2 light years.(Proxima is Latin for "next to" or "nearest to")Alpha Centauri is the closest star system to us at a distance of approximately 4.3 light yearsThe Centauri system is a triple star system Centauri A and B have a mean separation of 11 AU's and are similar in size and temp to the Sun.Centauri C is a red dwarf it can not be seen with the unaided eye and was not discovered until 1918See related link for more information.
