Part of the International Space Station? I dunno. Looks like some sort of cover for a vent/jet/drain. What is it's composition and how big is it? Weird ear ring!

It's to keep debris out of the air orifice. There really shouldn't be any debris in the heater. However, debris can get in the heater. It should just snap back in.
