When you look up at the sky at Proxima Centauri, you see it as it was 4.2 years
ago. It will be another 4.2 years from now before somebody at Proxima Centauri
sees you looking down at him. He will be troubled, and will wonder why you are
looking down at him.

How long will a spaceship traveling at the speed of light reach Proxima Centauri?
About 4.2 years.
How long would it take a ray of light to travel to Proxima Centauri from the Sun?
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
If a spacecraft travels at 17.3 km per second how long for craft to go from sun to Proxima Centauri?
At 17.3 kilometers per second the craft would require 73,128.5 years to reach Proxima Centauri; a distance of 4.22 light years.
How long would it take light to travel from the Sun to the nearest star?
approximately 4 years and 3 months (from proxima centauri)
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.
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.
Planets seen on the way from earth to Proxima Centauri?
Depending on the planets positions at the time and if you are lucky with your trajectory. * Mars * Jupiter * Saturn * Uranus * Neptune * and then nothing for a long long time
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.
How long would it take to travel to the nearest star at 20000 miles per hour?
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!
If a hypothetical vehicle could reach Pluto in three seconds how long would it take to reach Proxima Centauri?
Ask James Kirk - faster than light is science fantasy.
How long doessecon closest star take for light from tat star to reach us to earth?
4.37 years. the star is Alpha Centauri ---- That's wrong. The closest star is the sun and it takes 8.3 minutes for light to reach us. when phrased nearest star it can be a trick question.. Alpha Centauri is the nearest star besides the Sun.
Where in the Milky Way is .08 light years from earth?
There is nothing there. The nearest known star to sun (Proxima Centauri) is 4.2 light years far. But the diameter of Solar system is .05 light years long.
