Light goes at 670 million miles per hour, which is 670 times faster, and it takes 4 years to get to the nearest star. So at one million miles per hour it would take 2700 years to travel there.
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.
First, our Sun of course. Distance: About 8 minutes for a ray of light.The next known star system is Toliman (Alpha Centauri); distance about 4.3 light-years (it takes light 4.3 years to travel from there to here). The nearest known individual star after the Sun is Proxima Centauri, part of the Alpha Centauri system.
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.
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.
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
The distance from the Sun to Proxima Centauri is about 4.24 light-years or roughly 40 trillion kilometers. At a speed of 17.3 km/s, the spacecraft would take around 7,865 years to travel from the Sun to Proxima Centauri.
It would take light approximately 4.3 years to travel from the Sun to the nearest star, Proxima Centauri. This distance is about 4.24 light-years away, making it the closest known star to our solar system.
The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.
Incredible as it might sound, even traveling at 20,000 miles per hour the trip to Proxima Centauri (V645 Centauri) would take 142,241 years!
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.
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.
The Space shuttle cannot go beyond low earth orbit, but assuming you were traveling at the shuttle's orbital speed of 17,600 mph it would take approximately 7 months to reach the sun (the nearest star to earth), and approximately 160,000 years to reach Proxima Centauri, the nearest star to the sun.
Proxima Centauri is about 4.2 light years from Earth.About 4 x 1013 kilometers (40,000,000,000,000)About 2.5 x 1013 miles (25,000,000,000,000)About 265,606 AUAbout 1.3008808 ParsecsIf the Earth was only an inch from the Sun, at the same scale, Proxima Centauri would be 4.2 miles away.It is the closest star to us, after the Sun.
Spacecraft can never travel in a straight line. They have to go in curves, because of the way gravity works. But if you could travel from Earth to Proxima Centauri in a straight line, it could really cut down on the distance you'd have to cover, and on the time the trip would take you. At 55 miles per hour, you could make it in just a little bit more than 51 million years.

No. Alpha centaurii or Proxima centaurii (Proxima=Closest in Latin) is the closest star to earth except the sun, with an approx. distance of 4.28 lightyears (the distance that light can travel in 4.28 years). so alpha centaurii is a star not a planet. if it has planets orbiting around it is unknown.
