TOI-3540 A b: A Jupiter-Like World Around a Star
TOI-3540 A is a star with 1.08 solar masses and 1.23 solar radii, making its reported mass and radius estimates larger than the Sun's. Its temperature is 5810 K, and its age is 6 billion years. One planet is known to orbit this host.
That planet, TOI-3540 A b, is classified as Jupiter-like because its radius exceeds four times Earth's. Its radius is 23.5 Earth radii, larger than Earth's, and its mass is 375 Earth masses, also larger than Earth's and roughly 1.18 times Jupiter's mass. Its mean density is 0.158 g/cm³, or 0.0288 times Earth's. The planet completes an orbit in 3.12 days.
TOI-3540 A b was discovered in 2022 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness.
