Extrasolar planets, even the closest, which is Proxima Centauri b, is 4.3 light-years away. This is a distance of about 40.7 trillion kilometers, and no human projectile has reached that far as of yet. In addition, the next nearby habitable planets such as Ross-128 and Tau Ceti are 11 (104 trillion km) and 11.9 light-years (113 trillion km) away, respectively. It would take us 61 years to get to Proxima Centauri b, and 157 and 170 years to get to Ross-128 b and Tau Ceti b, with a 7% high-speed starship. Furthermore, the actual starship needs acceleration and deceleration, and if we consider that, it would take more than 100 years to get to Proxima Centauri b. At this time, there are still no prospects for existing technology to achieve such speeds.
What will the next stage look like if the day comes when the human race can visit these planets with such technology? Right now it is only in our imagination.
We don’t have any information about what the surface of the planet looks like, but still, we can enjoy these imaginary worlds.
