The discovery of exoplanets has intensified
interest in the search for extraterrestrial life, especially
for planets orbiting the sun like stars in habitable zone.
The study of planetary habitability also considers a
wide range of other factors in determining the
suitability of a planet for hosting life. This study aims to
determine to explore the variety exoplanets like giant
planets, terrestrial planets, habitable planets, and earth
like planets. The method for searching that planets are
using five different methods, like radial velocity method,
transit method, gravitational micro-lensing, astrometry,
and direct imaging. From the study process obtained
that there are 1.271 giant planets, 211 terrestrial
planets, 291 habitable planets, and 2 earth like planets.
