For the transit method to work, a planet must pass almost
perfectly along our line of sight, the chances of which are around 0.5 percent for an Earth - sized planet (in an Earth - sized orbit) and 10 percent for a Jupiter - sized planet (if it orbits near its star)[source: Ames Research Center, FAQ].
And although it's meant to be hidden
along with your other audio visual cables - and works
perfectly without direct
line of sight thanks to operating on Wi - Fi instead
of the sometimes pesky Bluetooth protocol - the Chromecast Audio is definitely not an eyesore.
