we talked about this in great detail yesterday on HN with some fantastic comments

NASA has a neat exoplanet catalog where you can also switch to its solar system view

* https://science.nasa.gov/exoplanet-catalog/lhs-1140-b/

Super-Earths are interesting but not technically habitable, at least not by humanoids, the gravity would be insane

There are new telescopes and techniques coming online really soon that can potentially find closer to Earth-sized planets but they probably won't be within 50 light years

adding: hmm maybe gravity not too horrible on 1140b but still INTENSE

(assuming Google's "AI" is correct)

> Gravity Formula: \frac{Mass}{Radius^2}\)Calculation: \(5.6 \div (1.73)^2 = 5.6 \div 2.9929 \approx 1.87\)

> if you weigh 150 lbs on Earth, you would weigh roughly 280.5 lbs on 1140b
