It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
Sunlight takes 8.4 minutes to travel 93 million miles to Earth. It would take us that long to reach the Sun at light speed.
The speed of light is ~186,282 Miles per second. You do the math.
Traveling 39 light years would take 39 years at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
35 minutes Speed of Light is 671 million miles per hour.
It takes about 1.28 seconds for light to travel from the moon to Earth. So if the moon were to travel at the speed of light, it would complete an orbit around the Earth in approximately 1.28 seconds.
To determine how long it would take to travel 434 light years, we need to consider the speed of the spacecraft. For example, at the speed of light, it would take exactly 434 years. However, if traveling at a more realistic speed, such as 20% of the speed of light, it would take approximately 2,170 years. Current technology does not allow for speeds anywhere near the speed of light, making such a journey impractical with today's capabilities.
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.
Objectively, about 26,000 years - but IF (and you cannot!) you could travel at the speed of light, it would seem like no time at all had passed.
It would take roughly 0.06 seconds if you find it using the equation S=Vt xD(time = Distance / speed)
You cannot travel that far at any speed now attainable. You would be dead when you arrived. Edit: (If you wasn't traversing at/close to Light Speed).
