First, we need the distance of Europe and Wolf-359 from Earth.
- The distance of Europe from Earth is:
- The distance of Wolf-359 from Earth is instead 7.795 light years. However, we need to convert this number into km. 1 light year is the distance covered by the light in 1 year. Keeping in mind that the speed of light is
, and that in 1 year there are
365 days x 24 hours x 60 minutes x 60 seconds =
, the distance between Wolf-359 and Earth is
Now we can calculate the time the spaceship needs to go to Wolf-359, by writing a simple proportion. In fact, we know that the spaceship takes 2 years to cover
, so
from which we find
