TOI-1451 and Its Neptune-Like Planet
TOI-1451 is a star 300 light-years from Earth with a mass of 1 solar masses and a radius of 1.02 solar radii. Its temperature is 5800 K, and it is 4 billion years old. One planet orbits this host.
That planet is TOI-1451 b, a Neptune-like world discovered by transit in 2024. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-1451 b has a mass of 15.2 Earth masses and a radius of 2.61 Earth radii, both larger than Earth's corresponding values. Its orbital period is 16.5 days, and its mean density is 4.7 g/cm³, 0.854 times Earth's.
