The exoplanet, TOI-715 b, is about one and a half times the width of Earth.

Unfortunately super earths aren’t viable for us. They would both have crushing gravity and that gravity would make rockets leaving the planet impossible. Fuel to weight ratio would ensure no one could ever leave.
Don’t need to leave that planet in order to colonize it.
If we have technology to traverse 100+ ly, we likely have the technology to escae its gravity
