The only way for us to survive that distance would be a conscious transfer to a database where upon entry of the new planet's atmosphere we would redownload our conscious into another being wether it be robot or extraterrestrial. Unfortunately our tech isnt good enough for that yet.

It is possible, you can also do cloning too, but the issue remains:

even if we do send an electromagnetic wave, it would take 500 years for it to arrive on it.
