Oh I forgot it was my turn! Ok, here is the next one, hopefully not too stupid:
Shape: Roughly circular
Size: in reality, probably no more than a few mm in diameter (See defining characteristic)

Defining Characteristic: When viewed on a two-thousand inch TV screen, it appears to be approximately 10 feet in diameter.
