nostr:npub1knzsux7p6lzwzdedp3m8c3c92z0swzc0xyy5glvse58txj5e9ztqpac73p Amazingly, the radio power received on earth from the Voyager spacecraft transmitting in the GHz range at 20 W is about an ***attowatt (1e-18 W)***, since they are on the order of 20 billion kilometers from earth !

See info here (it refers to Voyager 1 but for these estimates I think both Voyager are about the same figures):
