How long does it take light to travel from Alpha Centaury the nearests star to your sun to your solar system?
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.
Why would it take long for alpha centauri light to reach earth?
along long long long time
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.
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.
When we look into the night sky we are actually looking into the past. How do you explain this?
The speed of light is not infinite. Even the light from our own Sun takes over 8 minutes to reach us and it is so much closer than any star. The light from Alpha Centauri takes over 4 years to reach us so when you look at it tonight you are seeing what it was really like in 2004. If it exploded last year we wouldn't know about it until 2012/13 when the light reached us. And Alpha Centauri is one of the three nearest stars!

How long does it take for light from centruai?
It takes light approximately 4.3 years to reach our solar system from Alpha Centauri.
Leaveing alpha centauri you will reach in 4.3 years?
Could be anywhere - depends on which direction you are heading.If you're very lucky, you might reach our Solar System
How long does it take a starship traveling at half the speed of light to get to Alpha Centauri?
First of all, there has never yet been any such thing known to earth as a starship. If an object left Cape Canaveral at 1/2 the speed of light, and maintained a straight-line course toward the place where Alpha Centauri would be when it got there, it would reach Alpha Centauri after the clock on the launch-pad had ticked off 8.8 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)
How old is Alpha Centauri compared to the Sun?
The Heliopause is at a distance of appx 120 AU from the Sun. That is around 0.0019 light years. Te Alpha Centauri star system is 4.365 light years away from the Sun, and almost the same distance away from the Heliopause.
Which is the closest star from earth?
The star closest to earth is the sun, at a distance of roughly 93 million miles.Light from the sun reaches us in a little over 8 minutes.The next closest star is Alpha Centauri, about 278,000 times farther away thanthe sun is. Light from Alpha Centauri travels for about 4.4 years to reach us.
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.
How long will it take you to reach Alpha Centauri 4.37 light years away if you are travelling 16000 mph?
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.
Info on the constellation alpha centauri?
"Alpha Centauri" isn't a constellation. It's a single star ... the brightest one we seein the constellation "Centaurus".It's also the nearest star to us outside of our solar system. It's so close to us thatthe light from it takes only 4.4 years to reach us, at 186,000 miles per second.
