Do you want to travel to another planet? Or perhaps even another star system?
Then you can use this calculator to work out how long it will take you, how much energy your spacecraft needs and what your maximum velocity will be. If you travel close to the speed of light, you can also see how much time it will take from your point of view and from the point of view of the people on earth. You can also see how the length of your spacecraft will shorten for observers watching it from earth, if only they had powerful enough telescopes.
This is the simplest way to use the space travel calculator:
- Enter a distance to a planet or star. Don't know any? Then type Pr and press the down arrow. The distance to Proxima Centauri appears. Select it and the distance will be filled in. Try other places in space.
- Click Calculate. The calculator determines the remaining unfilled values.
- Click Run. Watch the space rocket travel from earth to your destination. Also watch the clocks of the observer and the traveler.
