How long in time at lightspeed to alfa centauri?
Alpha Centauri is a binary (Possibly triple) star system.Alpha Centauri A/B is 4.37 light years from us.Alpha Centauri C is 4.243 light years from us.
What is the fourth nearest star to our solar system?
Proxima Centauri is the closest star to our Sun, at 4.2 LY. Curiously, even though it is the closest, it is not visible to the naked eye! Proxima Centauri is a tiny red dwarf star, and requires a fair-sized telescope to see. For a long time, many people thought that the closest star was Alpha Centauri, which isn't entirely incorrect. The Alpha Centauri system is actually a double star with a very distant triple; Alpha Centauri A (also known as Rigel Kent) and Alpha Centauri B form a binary system, and Proxima, Alpha Centauri C, is very distantly linked at about 0.3 LY.
How long does it take for a radio transmission to go from earth to alpha centauri and back?
It takes about 4.37 years for a radio transmission to travel from Earth to Alpha Centauri (the nearest star system) and another 4.37 years for the signal to travel back. This means a total round-trip communication time of around 8.74 years.
Why would it take long for alpha centauri light to reach earth?
Alpha Centauri is 4.37 light-years away from Earth, which means it takes light, the fastest thing in the universe, 4.37 years to travel that distance. Although light travels at a speed of about 186,282 miles per second, the vastness of space makes this journey take years.
When will alpha centauri b die?
Science is unable to know for sure if there is life on the planets surrounding Alpha Centauri. However, it has been identified as one of the environments likely most similar to earth's environment.
Proxima century and alpha century?
Proxima Centauri (note spelling) and Alpha Centauri are stars in a trinary some 4.3 light years from earth (at the present time).
What is the closest star other than the sun?
At any given moment, it's one of the three stars making up the alpha Centauri system. The one that can get the closest is alpha Centauri C (aka Proxima), but depending on where it is in its orbit, it's possible for either alpha Centauri A or alpha Centauri B to be slightly closer than Proxima at a soecific point in time.
What is the third star from the sun?
The third closest star will be either Alpha Centauri A or Alpha Centauri B depending on the time of observation.
How long in time at lightspeed to alfa centauri?

If you were travelling thought space at 70000 kilometers per hour how long it take to get to the star system Alpha Centauri?
Assuming that you start from earth, travelling that slowly to Alpha Centauri would take quite a bit of time. Alpha Centauri's about 4.367 light years away, which means at the suggested speed of 70,000 kilometers per hour, it would take you 673.26 centuries to get there. You definitely want to go much faster to get there.
What is the 3rd closest star on earth?
ANSWER:With the Sun being the first, Proxima Centauri is the next closest at 4.22 light years away in the Alpha Centauri star system. See the related link for more information.
How long would it take for it to get from the sun to alpha centauri travelling at 1516 times the speed of light?
Just because you NEED something by a certain time does not prompt users to actually answer your question.However, I'll give a few pointers.Depending on which part of Alpha Centauri you intend to go to, there are three stars with different distances.Alpha centauri A - about 4.365 light years from us.Alpha centauri B - about 4.364 light years from us.Alpha centauri C - about 4.243 light years from us.The speed of light is 299,792,458 meters per second.At 1,516 the speed of light is 454,485,366,328 meters per second.So all you have to do is calculate which Alpha Centauri you want to go to and divide the distance by the new speed.
How long does it take for a radio transmission to go from earth to alpha centauri and back?
It takes about 4.37 years for a radio transmission to travel from Earth to Alpha Centauri (the nearest star system) and another 4.37 years for the signal to travel back. This means a total round-trip communication time of around 8.74 years.
Is the nearest star the proxima centauri?
Not counting the Sun itself, Proxima Centauri can be the nearest star that we know about.Proxima (Alpha Centauri C) is part of the Alpha Centauri system. Depending on where it is in its orbit, it might be closer to us than Alpha Centauri A and Alpha Centauri B, or it might be further away.Astronomers also aren't absolutely positive that the Sun doesn't have a distant binary red or brown dwarf companion. Such a companion would be difficult for us to detect. This hypothetical companion has even been given a name, just in case we end up finding it: Nemesis.It currently seems unlikely that Nemesis exists. The WISE survey (which could have detected stellar objects with a surface temperature of just 150 Kelvin - far below freezing - at a distance of 10 light years, considerably further away than the Alpha Centauri system) should have found it if it were there. Also, the reason it was originally hypothesized to exist (periodic mass extinctions on Earth, the reason for the name Nemesis) is no longer considered to be consistent with the proposed Nemesis mechanism.So, after all that: Probably yes, at least part of the time.
How old is Alpha Centauri compared to the Sun?
Alpha Centuari is a star 4.4 light years away. Which is about 44 trillion km (44,000,000,000,000 km) or 44,000 Billion km. Its actually more like 42,479,700,000,000 km if you were exact.
What is the name of our nearest star to the sun?
For a long time, astronomers thought that the star Alpha Centauri was the nearest star (actually, TWO stars; they are a binary system) to our Sun, at about 4.5 light years. But then they discovered a red dwarf Proxima Centauri that is about .3 ly closer! Because Proxima Centauri is so small and dim, it cannot be seen with the naked eye.
