Another notable planet is HD 224538b. It is a giant planet with at least ~5.97 times the mass of Jupiter and its orbital period around its host star is ~1200 days. The orbit of HD 224538b has a large eccentricity of about 0.46. The host star of HD 224538b is an F-type star with ~1.34 times the mass, ~1.54 times the radius and ~2.95 times the luminosity of the Sun. Furthermore, the star's effective temperature is ~6097 K and it is a metal-rich star with almost twice the Sun's metallicity. HD 224538b is basically a massive eccentric giant planet orbiting a super metal-rich star, a relatively rare type of planet.
