On the log scale that I use to make my planet cookies, the Sun is about 3.5 inches in diameter. HL Tau, at 2000 AU wide, comes in around 8 inches.

Of particular note is the World Wide Web.

Notable worlds include Diamond World (second from lower left), Pangaea (just above and to the left), and the Norse Ragnarok world tree representation courtesy of Erik (above Blackfriars world)
