Scientists have discovered a world that is likely rocky and 95% of the size of #Earth. The planet, called TOI 700 e, is orbiting around a star and could have liquid water on it, #NASA says. This is the fourth planet discovered in the TOI 700 system — the other planets are named TOI 700 b, c, and d — which is 100 light-years away. TOI 700 is a star the planets orbit around, but only d and e orbit in the "habitable zone." Via @cbsnews • @Riemoh
