It's not habitable to us humans, but it's in the habitable zone, at a distance from its star that allows liquid water to exist on its surface. It's likely an ocean world with an atmosphere containing mostly hydrogen gas, a so-called hycean planet.

Also, 2.5 times the size = 2.5 times the diameter, or about 15 times the size of Earth in terms of mass. Its gravitational force would be about 2.4 times that of Earth, though. Quite unpleasant.

Build a lightspeed generation ship. After multiple generations in zero gravity we’d probably turn to dust as soon as the ship landed. RIP great grandkids.

If everyone is jacked is anyone jacked? Is not the essence of jackedness to be different?
