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 systemi have recently reopened my pc to find all the names i have designated years ago, and saw some keepers and many flawed names.

Forty-four planets in solar systems beyond our own have been discovered in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less. The planets located in our own solar system are by far the most well-known planets for the majority of people yet, as you might guess, there are many planets located outside of our own solar system these planets are known as extrasolar planets, or exoplanets.

Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star host stellar abundances are good proxies of planetary abundances, but only for refractory elements.

Extrasolar planets are planets that orbit stars other than the sun a planet is defined generally as an object too small for gravitational pressure at its core to ignite the deuterium-fusion reaction that powers a star in august 2006, the international astronomical union (iau) officially defined a.

  • A unique branch of astronomy is the search for extra-solar planets - exoplanets this takes more observation than viewing through a normal telescope an ex tras o lar planet , or exoplanet , is a planet which orbits a star other than our sun, and therefore belongs to a planetary system other than the solar system.
  • Planets around other stars proved very elusive to find until 1995, when astronomers in geneva detected an exoplanet using the radial velocity (or doppler) technique since that time, hundreds of exoplanets have been discovered in this manner, by observing displacements in a star's spectral lines due to the doppler effect.
