HD 23596 b is an exoplanet approximately 170 light years away in the constellation Perseus. The planet is very massive, at least 7.8 times that of Jupiter, classifying as mid-superjovian. Based on its mass, the planet would probably be a gas giant with no solid surface. The planet orbits at the average distance of 2.83 AU, taking 1565 days to complete its orbit with average velocity of 19.7 km/s. The eccentricity of the planet’s orbit is higher than all the planets in the Solar System, bringing as close as 2.00 AU to as far as 3.66 AU from the parent star.[1]
The planet was discovered by Perrier et al. in 2002 using his radial velocity technique to look for changes in inward (blue-shifting) and outward (red-shifting) radial stellar motion in the sky.[1]
