Chronos

The planet orbiting Iota Horologii was the first planet that I gave a name to. This planet was quite interesting to me, and it deserved a special one: Cronus.

Beginning in 2004, I started a hobby of giving extrasolar planet names to the planets outside the solar system. I have recently reopened my PC to find all the names I have designated years ago, and saw some keepers and many flawed names.

Because the International Astronomical Union (IAU) is not giving extrasolar planets "official" names (comparable to the planets of the Solar system), I currently designate names for the fun. I only name planets after mythology, and I only name prototypical or important planets. I am slow in my work, so some planets I have not names may not have been given a name (as of yet).

Summary

A far back as 2004, I began to study about planets outside the Solar system (called extrasolar planets). But because not much was known about them (along with only knowing a few at the time), all extrasolar planets were named after their parent star (e.g. 51 Pegasi b). Some astronomers (or amateurs) desided to give some names to some of the most noted planets. The eariest I could remember was the name "Osiris" given to planet HD 209458 b (possibly the first true extrasolar planet name given).


Planet Name Mythology Root Connection
(in layman's terms)
51 Pegasi b Bellerophon Greek Pegasus, tamer [1] The first planet discovered around a Solar star. Located in the constellation of Pegasus
Gliese 581 c Ymir Norse frost-giant [2] Most Earth-like planet to date. Much larger than Earth.
HD 209458 b Osiris Egyptian underworld, death [3] Hellish planet that is in the process of dieing.
PSR B1620-26 c Methuselah Middle Eastern/Biblical elder, old Oldest planet discovered (to date).


Requested planet names

Note: I have not copyrighted these names and would love to see them be used for planetary nicknames.

Though all the planets don't deserve a name, some do. Some planets are unique or prototypical that they should get a name. But just like how only a few stars have and keep an official name, planets should be treated the same. Only important or prototypical planets should get a name.

Notes

  1. Names that were coined or proposed by Edasich
  2. Names that were coined or proposed by BlueEarth
  3. The original name chosen was Chronos. This name was part of W. Lyra's proposition on naming exoplanets, and chose this name out of all my proposals as the name form Iota Horologii b. However, he reworded the planet Cronus.
  4. Names that were coined or proposed by Sedna
