Whenever these articles come up that talk about sister earths the only thing I’m really interested in is how far away it is, so here you go:
> Researchers have been excited to use the new telescope to explore it and its six siblings, which are all roughly the size of Earth and which orbit a star 12 parsecs (39 light years) from Earth.
- dekhn 4y agoI guess if you could get a probe up to 0.1c (project orion), that's only 390 + 39 years to get direct images from within the solar system. But in 390 + 39 years, I assume imaging from our own solar system will have gotten significantly better making direct imaging possibly unnecessary.

Interesting that TRAPPIST-1 is the farthest on the list. I think I'd just start with Alpha Centauri- 40+4 years for a return of direct images of a planet orbiting in a trinary star system.
