Facts About Planet HD 189733b:

Type: "hot Jupiter" gas giant

Distance from Earth: 63 light-years, in the constellation Vulpecula ("The Fox")

Day/Year: 2.2 Earth days (planet is tidally locked and one side always faces the parent star)

Temperature range: 1,800 degrees Fahrenheit (1,000 degrees Celsius) on the day side, 1,200 degrees F (650 degrees C) on the night side

Wind speed: 4,350 mph (7,000 km/hr)

Conditions: glass particles in atmosphere create blue color.

In 2007, astronomers created a heat map of the surface of HD 189733b showing the hot spot on the side permanently facing the star. This was the first surface map made of a planet orbiting another star.
