An article appeared recently about an earth-like planet, HD 137010 b, which is around an orange start, HD 137010. Of course, I wanted more information
HD 137010 b is an unconfirmed exoplanet detected around star HD 137010. More observations are needed to confirm its existence.

Distance from the star: 0.88 AU
Orbit around star: 355 days
Temperature: 205 K | -68.15 °C
Estimated size ~ 1.06 earth diameter
Earth-like in the sense of size, but the environment is more like an icy planet.
Star HD 137010 - Orange star HD 137010 is located 146 light years away from the Sun. It is a single star of spectral class K3.5V, that has 73 % of solar mass. There is at least one exoplanet in this system.
