# How Long Will It Take To Travel 50 Light Years?

Ha ha.
It depends on how fast you go.
If your rate of speed is about the same as the big powerful rockets that put satellites in orbit around the earth you will be going about 40,000 kilometers per hour (25,000 miles/hour).
At that rate it will take almost 400-years.
If you could go half as fast as light it would take 100-years.
If you could go as fast as light it would only take 50-years.

Thanks, i did not realize a light year was relative to light speed that way my wife asked me and i couldn't answer it for her. By the way that is how far away the white dwarf star is. Its a solid diamond, so they say as big as the earth and has the mass of the sun, fun little fact. I guess nobody will get there hands on it any time soon
It depends on a lot of factors, for instance the most probable way would be use constant acceleration to maintain gravity on the ship. If you assume an acceleration rate to keep the ship at 1g then it would take 51 years from the point of view of people left on earth but it would only take 7.7 years from the point of view of a person on the ship. Whichever way you choose to go you have to factor in time dilation due to your speed.

50 years at the speed of light.

Thanks now i think it was a dumb question I guess that is why they have this website.
