Sentences with phrase «gaseous planet»
A "gaseous planet" refers to a type of planet that is mostly made up of gas, like those in our solar system such as Jupiter and Saturn. It means that the planet doesn't have a solid surface like Earth, but rather is composed mainly of gases like hydrogen and helium. Full definition
The current lack of small planet detections is likely to correspond to underabundances of these objects, as noted previously (Southworth et al. 2007; Mazeh et al. 2005) and probably corresponds to a lower limit to the existence of gaseous planets because of evaporation.
