How Far Is Alpha Centauri From Earth In Au


Earth-like planet spotted orbiting Sun’s closest star ...

Alpha Centauri is the binary system of Alpha Centauri A and Alpha Centauri B, which are separated by about 10-30 AU. It's very, very close in terms of interstellar distances to Proxima Centauri, which is a red dwarf that orbits Alpha Centauri A and B at a distance of 13000 AU, or 0.2 LY - a remote enough orbit that it makes sense to keep track ...

Hertzsprung-Russell Diagram | COSMOS - Swinburne

The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.

Build a Solar System Model - Exploratorium

I made my first scale model on a roll of teletype paper tape (anyone remember that stuff?) On this 1-inch tape, my Sun was the size of the tape - 1 inch in diameter. It all started out well. Mercury was only about 3-1/2 feet from the sun and Earth was almost 9 feet from the Sun. What I didn't bargain for was that Pluto was 354 feet down the tape!

Alpha Centauri - Wikipedia

Alpha Centauri C is about 13,000 AU (0.21 ly; 1.9 × 10 ^ 12 km) from Alpha Centauri AB, equivalent to about 5% of the distance between Alpha Centauri AB and the Sun. Until 2017, measurements of its small speed and its trajectory were of too little accuracy and duration in years to determine whether it is bound to Alpha Centauri AB or unrelated.

Luhman 16 - Wikipedia

Luhman 16 is the nearest-known star/brown-dwarf system to Alpha Centauri, located 3.577 ly (1.097 pc) from Alpha Centauri AB, and 3.520 ly (1.079 pc) from Proxima Centauri. [note 3] Both systems are located in neighboring constellations, in the same part of the sky as seen from Earth, but Luhman 16 is a bit farther away.
