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.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
Traveling to another galaxy at the speed of light would take an incredibly long time. The closest galaxy to us, the Andromeda galaxy, is about 2.5 million light-years away. This means it would take 2.5 million years to reach Andromeda at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
14 Billion years
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.
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.
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.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
300 billlion years
About 9,177,187,388 hours (1,047,624.13 years)
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
About 4.2 years.
It would take approximately 40,238 years to travel 20 light years at 36,000 mph. This calculation takes into account the limitations of current space travel technology and the vast distances involved in interstellar travel.
If you are asking how long it would take to travel the distance of 123.23 light years, then that would depend on how fast you are traveling. Because a light year is a measure of distance not time.
