The distance of K2-19b from here is about 111light years (6.25x10^17 miles away) in Leo constellation.
The planets are always very far from us. Unless we come up with aircraft to beat the speed of light many times, then we would have the hope of reaching such planet in this century.
Lol. Or maybe we can figure out a way to teleport ourselves there
Ok. Lets go teleporting then :)
