TOI-4127 b is a confirmed gas giant type exoplanet orbiting the faint F-type main-sequence star TOI-4127, about 1,042 light years away from earth. The planet is known as a warm Jupiter, a type of gas giant exoplanet that is not a hot Jupiter but is also not a cold Jupiter.[1][2]
Physical characteristics
This planet has a mass of 2.3 |♃|J}}}}}} and a radius of 1.096 |♃|J}}}}}}.[3][2]
Orbital characteristics
TOI-4127 b orbits TOI-4127 at a distance of 0.3081 astronomical units (AU) and an orbital eccentricity of 0.75. The planet takes 56.4 days to orbit its parent star. Its orbit lies at a orbital inclination of 89.3°.[3] The exoplanet orbits its parent star at a high eccentricity making it also a eccentric Jupiter.[4]
