Planets That Can Host Aliens Life!

Here four planets details have been given which could have Life on them (microorganisms are also part of life) here are four planet which are mentioned Below 

Tau Ceti e, Gliese 163c, Gliese 581d, Tau Ceti f 

I) Tau Ceti e

Tau Ceti e, also known as 52 Ceti e, is an exoplanet orbiting Tau Ceti that was detected by statatistics of data analyses of the star's variations in radial velocity that were obtained using HARPS, AAPS and HIRES.

• Distance to Earth: 11.9 light years
• Radius: 56,693 km
• Orbital period: 168 days
• Discovered: 19 December 2012
• Orbits: Tau Ceti
• Apparent magnitude (V): 3.5

II) Gliese 163 c
