I think that Alpha centauri could host the closest Earth-like planet.

A study shows that 22% of G and K-type stars could have Earth-like planets orbiting in the habitable zone.

There are 9 Sun-like stars within 25 light-years. If we make the calculation, two of those stars could have an Earth-like planet.

One of those two exoplanets could be Tau Ceti e. Which exoplanet could be the other one?

7 out of the 9 closest Sun-like stars have low metallicity. The only two stars with high metallicity are Alpha Centauri A and Delta Pavonis, but this star is suspected to be variable.

What do you guys think?

We know it has a planet now in the Goldilock zone. I predicted it might have one before the discovery. I suspected there might be one for better words.
