A light-year is 9.4605284 × 10^15 meters. So, 50 light years is 4.7302642 × 10^17 meters. A space shuttle travels at about 8000 meters / second. So, it would take 5.91283025 × 10^13 seconds, which is 1 873 702.86 years. There ye go - 1.87 million years.

It really depends on how fast the shuttle is going.
The faster the shuttle goes, the shorter the time. But, it can never be less than 50 years as nothing can go the speed of light. The other poster has a specific answer for orbital speed. So, somewhere between 50 years and 1.87 million years, depending on the velocity of the shuttle. |

The current speed of the space shuttle in orbit is five miles per second. The speed of light is 186 million miles per second. Since there are 32 million seconds in a year, in a full year the space shuttle travels 157 million miles and light travels 5,865,696,000 million miles. So it will take the space shuttle 37,2 million years to travel the distance that light travels in one year and 1860 million years (1.86 billion years) to travel 50 light years.

Light travels at around 67 million mph while the Space Shuttle goes about 17,000 mph. There are 8760 hours in a year. The question can only be expressed in millions of years. There aren't enough digits on your calculator. Honestly, who the hell knows or cares?
