I think mineral-rich asteroids would be a likelier first destination for interstellar colonists than an Earth-like planet. The Earth's gravity well is an enormous impediment to space travel. And in micro gravity, we can fly! A large enough asteroid with a hollowed out core with a stable star nearby to provide energy would be the kind of place I'd expect to see colonized first. Planetary scale terraforming can come later. Having said that, this is an exciting discovery. Kudos to the team that discovered these planets.
