As the distance to Alpha Centauri is 4.367 light years then traveling at the speed of light it would take 4.367 years to get there. However due to the effects of special relativity the travelers would experience the trip as instantaneous (i.e. taking no time at all).
From the earth if the travelers sent back a message as soon as they arrived, that message would arrive 8.734 years after the travelers departed.
Proxima Centauri, roughly 4.243 light years from our Solar System. Its a Red dwarf and is part of Alpha Centauri system which includes 3 stars. Alpha Centauri A and Alpha Centauri B are about 4.37 light years away. and the planet Eris is red it is about 3 billion miles away from the Sun and it is 1 billion miles away from our Earth.Proxima Centauri4.2421 light years away
About 4.2 light years
The closer the light source the larger is the shadow. You can understand this effect using the paraxial aproximation of light theory. If you draw lines from the light source to the edges of an object, there is an angle (call it alpha) between the these lines and the orthonormal vector to the object. The shorter the distance between the light and the object, the higher is alpha (because the height of the object is always the same): tan(alpha) = (height of the object)/(distance between light and object) Of course the relationship between the height of the shadow and the angle is the same: tan(alpha) = (height of the shadow)/(distance to the wall in which the shadow is proyected) So, the higher the angle alpha (and closer the distance between light and object), the heigher is the shadow.
The eyeglass has a refracting effect that bends the path of light into your eye at the right angle.
Approximately 40.1 trillion kilometres. The distance of Proxima from here is 4.24 light-years. A (Julian) year is 3.15576 × 107 seconds, and the speed of light in vacuo is 2.997 924 58 × 108 metres per second. That makes a light-year 9.461 × 1015 metres. 4.24 times 9.461 × 1015 metres is 4.011 × 1016 metres, which is 4.011 × 1013 kilometres. Round to the number of significant figures in the least precise factor.
Alpha Centauri is a triple star system. Alpha Centauri A, B & C or Proxima Centauri. Alpha Centauri A & B are 4.37 light years from the Earth whereas Alpha Centauri C is 4.243 light years.

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.
Alpha Centauri is the closest star system to Earth, located about 4.37 light-years away in the constellation of Centaurus. It consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest known star to the Sun.
The distance to Alpha Centauri is about 4.3 light-years.
That would be "Alpha Centauri". The distance is about 4.4 light-years.
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.
The closest star system to our Sun is Alpha Centauri, which consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest to the Sun at a distance of about 4.24 light-years.
Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.Proxima Centauri, which is probably part of the Toliman (Alpha Centauri) system.
Alpha Centauri, which is 4.2 light years away from the Earth.
The two objects most likely to be 4 light years apart would be two stars in our closest neighboring star system, Alpha Centauri. This system consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.
4.3 light years===========================Sorry. "Light year" is an answer to "how far", not "how long".Alpha Centauri is about 4.4 light years away from our solar system and everything in it,which means that it takes AC's light about 4.3 years to get here.
