I have a few questions about special relativity.

How is defined velocity ?

Let's say I'm heading to a planet at a constant speed v. If v is close to c, the time will be slower in my referential so 1 hour for me would be 1 day on the planet i am heading too (for example).

Does that mean that I age slower ?

If so, there would be no problem to travel to a very far planet if we were close enough to light speed, no ?

I am not even sure that "far" means anything actually.

Correct

Remember that from the rocket's ref. frame, the distances between the planets will be smaller. That's another way of looking at it.

Ok then. Thanks. The calculations are quite interesting and "encouraging", even though living 12 years in a spaceship with a constant acceleration (1g in the example) doesn't seem very ... nice.

This is exactly what I wanted to know, thanks.
