Study on the characteristics of exoplanets: Review

Abstract

Since the discovery of the first exoplanet 51 Pegasi in 1995, thousands of exoplanets have been discovered till date. They have been found orbiting around almost every type of known star including pulsars, binaries, and neutron stars. Compared to the planets of our solar system, these exoplanets possessed a wide range of masses, sizes, orbits, and other physical and chemical characteristics. The major classification of the exoplanets includes Gas Giants, Neptune-Like, Super-Earths Terrestrial types, however, studies suggest that a lot of other types of exoplanets are also present. In this paper, we review the characteristics which include masses, compositions, and orbital parameters of major types of exoplanets, and try to find the relationship between these prominent characteristics of exoplanets.
