Task: Text Categorization
Input (English): There are two known planets that orbit this kind of object, but a third is suspected to explain why the one is extremely hot, likely due to a recent collision. Over long periods of time, their atmospheres can accumulate methane, but like more massive objects, their atmosphere is fully convective. They fall into "L" and "T" spectral classes. A sure test for these is the presence of lithium, since stars begin to fuse lithium when they are at most one hundred million years old. A subclass of planetars, along with interstellar stars, FTP, identify these almost-stars too small to sustain hydrogen fusion.
Output (English): Science
