At a typical 18.6 miles per second the spacecraft travels at 1/10,000 of the speed of light, therefore it would take 43,000 years.
It wouldn't be possible using our current technology; with our current technology, it takes 10 years to get outside our own solar system. With technology that we could reasonably develop within the next 50 years, it should be possible to create a spacecraft that could travel 490 light years in ONLY 5,000 years or so. We know the basic principles for an Orion Nuclear Pulse Rocket, but it would be phenomenally expensive and impractical to build one to go 490 light years. The first such spacecraft will travel to much nearer stars.
it takes as much as 7000000 years to travel 600 light-years, so do the math 7000000 times 1million
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
A light year is a measure of distance not time. A light year is the distance light travels in one year. So for light to travel 6,300 light years, would take 6,300 years
300000 years at or 600 years at the speed of light in our fastest spacecrafts which travels 157,078 mph.

That would involve building spacecraft to exceed the speed of light, which at the moment is impossible.
About 4 light years.==========================Sorry. "Light year" is an answer to "how far", not "how long".Alpha Centauri is about 4 light years away from our solar system and everything in it,which means that it takes light, radio, and TV from us about 4 years to get there.
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.

Light years is not a time, it is a distance. It takes light about 6.025 years to travel 57 trillion km. In other words, 57 trillion km = 6.025 light years.
Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.
