Naming exoplanets

The names of exoplanets are hardly poetic. Lei us take the star HD 38529 as an example. The first exoplanet discovered orbiting this star is designated HD 38529 b, the next HD 38529 c, and so on. HD 38529 itself derives its name from its number In the star catalogue of Henry Draper, Most of the stars observed by the veloci metric method will be nearby stars such as HD 38529, already listed in various catalogues, or e Eridani, the fifth brightest star (in apparent magnitude) in the constellation of Eridanus. 51 Pegasi is number 51 in Pegasus, according to the system of Flamsteed, who numbered stars within constellations in order of right ascension (from west to east). Some other stars are numbered according to their sky coordinates. In the case of PSR 1 257+12, PSR signifies that it is a pulsar, and the numbers refer to its approximate right ascension (12 h 57 min) and declination (+12°). There are also planets with designations that reflect the names of the research programmes which detected them: for example, OGLE-TR-56 b was found by astronomers working on the Optical Gravitational Lensing Experiment, and TrES-1 was the first planet revealed by the Transatlantic Exoplanet Survey. We may rest assured, though, that some planets which will be studied in detail will receive more attractive names: HD 209458 b is already 'Osiris', according to those closely connected with itl
