Classes of these objects include ones that have strong metal hydride bands and sometimes water bands, called the L class, and ones that contain methane and water, called the T class.
Classes of these objects include ones that have strong metal hydride bands and sometimes water bands, called the L class, and ones that contain methane and water, called the T class. To distinguish these objects from other similarly sized objects, scientists check for a certain element's spectral line in the (*) lithium test. Gliese 299B was the first of these objects to be discovered. Sometimes referred to as the missing link between large planets like Jupiter and red dwarfs, for 10 points, name these stellar objects that do not have enough mass to begin hydrogen fusion, often referred to as "failed stars."
