HD 80606 b

HD 80606 b is a transiting hot Jupiter orbiting a G-type star (0.9 solar masses) in a 111-day orbit. It was discovered by the radial velocity method in 2001 and a transit was identified in 2011. Its orbit has a high eccentricity, 0.93183, varying from 0.03 to 0.89 AU. Given its transit and its high eccentricity, observation of its light curve offers considerable information, such as more-than-usually-determinable characteristics of its atmosphere. Planet characteristics:

• Host star: HD 80606.
• Discovery: by the radial velocity method in 2001.
• 217 ly - distance.
• 0.4603 AU - orbital radius (semi-major axis).
• 111 days - orbital period.
• 1 - radius in Jupiter radii.
• 4.2 - Jupiter masses.
• 1400 K - temperature when closest to the host star.
