Likewise, even if a planet orbits within the so - called Goldilocks zone surrounding its parent star where conditions are neither too hot nor too cold, its atmosphere may be hostile to life, a new study suggests.

Other astronomers find the detections convincing, although most reserve the name «planet» for bodies that form within a planetary system and orbit stars, says theorist Alan Boss of the Carnegie Institution of Washington in Washington, D.C. «They should call them «planetary - mass brown dwarfs,»» Boss says.

Nevertheless, Earthlings would not mistake Gliese 581g for their home planet — in addition to its so - called super-Earth dimensions, it orbits a star far smaller and dimmer than the sun, and its average surface temperatures would vary dramatically, from well below freezing on its night side to scorching hot on the day side.

On July 21, 2003, some astronomers provided evidence from recent discoveries of giant extrasolar planets in mostly inner orbits around host stars that planetary systems may be more common around stars whose spectra show an enriched abundance of elements heavier than hydrogen and helium — also called high «metallicity» (exoplanets.org press release; and Gonzalez, 1999).
