HD 56414 b: A Neptune-like Planet Orbiting a Massive Star
HD 56414 is a star 888 light-years away with one known planet, HD 56414 b. The star is 0.42 billion years old, with a mass of 1.89 solar masses, a radius of 1.75 solar radii, and a temperature of 8500 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
HD 56414 b is a Neptune-like planet discovered by transit in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. The planet's orbital period is 29 days, and its radius is 3.71 Earth radii. That radius estimate is larger than Earth's.
