TOI-3819 and Its Jupiter-Like Planet

TOI-3819 is a star 1820 light-years away, with an age of 4.5 billion years, a mass of 1.24 solar masses, a radius of 1.54 solar radii, and a temperature of 5860 K. Its reported mass, radius, and temperature estimates are all larger or hotter than the Sun's. One planet orbits this host.

That planet is TOI-3819 b, a Jupiter-like world discovered by transit in 2023. Transit means the planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-3819 b orbits every 3.24 days, with a mass of 353 Earth masses and a radius of 13.1 Earth radii, both larger than Earth's. Its mean density is 0.857 g/cm³, 0.156 times Earth's.
