TOI-2803 A and Its Jupiter-Like Planet
TOI-2803 A is a star 1610 light-years away with one known planet. It is 3.7 billion years old, has 1.12 solar masses and 1.25 solar radii, and a temperature of 6280 K, making it more massive, larger, and hotter than the Sun.
The planet TOI-2803 A b was found by transit in 2023. During a transit, a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-2803 A b has a mass of 310 Earth masses, a radius of 18.1 Earth radii, and an orbital period of 1.96 days, the time it takes to complete one orbit. Its radius exceeds Earth's, and it is Jupiter-like, a class for planets larger than four times Earth's radius. Its mean density is 0.287 g/cm³, 0.0521 times Earth's.
