Add to ORKGWe have measured the angular diameter of the transiting extrasolar planet host star HD 189733 using the CHARA optical/IR interferometric array. Combining our new angular diameter of 0.377 +/- 0.024 mas with the Hipparcos parallax leads to a linear radius for the host star of 0.779 +/- 0.052 R☉and a radius for the planet of 1.19 +/- 0.08 RJup. Adopting the mass of the planet as derived by its discoverers, we derive a mean density of the planet of 0.91 +/- 0.18 g cm^-3. This is the first determination of the diameter of an extrasolar planet through purely direct means
