Space Exoplanets or “extrasolar planets” are planets found outside our solar system. They are designated by affixing a lowercase letter, starting from “b” towards “z” depending on order of discovery, to their parent star’s Flamsteed designation or catalogue numbers. When PSR1257 + 12 B and PSR1257 + 12 C (they used uppercase letters for these very first ones because they did not yet use the current nomenclature), and later 51 Pegasi b, the first confirmed exoplanets were discovered in the early 1990′s, they were hailed as the most significant breakthroughs in the field of Astronomy since the Copernican Revolution and caused an uproar in the scientific community, and revived hopes of finding Earth-like planets and perhaps life outside the Solar System.
The most plausible explanation for this is that the commonly used indirect methods of exoplanet detection are biased towards large, massive objects with short orbital periods which make them the easiest to identify.
