so in total to go and come back home is 40 light years in total. so i dont know the exact math on how much is 40 light years & how long is it in regularearth year but lets say 200+ years. so if you was 20 years old and you went to the planet and back that means that you would arrive back on earth about 60something years old. but on earth year it would be 200+ years since you departed.

so you would get back on earth and everybody you knew is dead. what chu think?
