    to the earth. I will arrive at earth a little over 5 years from the time I depart, correct? How many years will I have aged as a passenger on the spaceship and how long will someone on earth have aged during my journey?

    According to an observer on the Earth, your journey took a little more than five years.

    According to you, aboard the spaceship, your journey was nearly instantaneous, and you would have scarcely aged at all.
