TOI-3785 b: A Jupiter-Like World Around a Cool Red Dwarf

TOI-3785 is an M2 V star, a small, cool red dwarf, located 260 light-years away. The star's reported mass estimate is smaller than the Sun's, at 0.52 solar masses, and its reported radius estimate is likewise smaller, at 0.5 solar radii. Its age is given as 8 billion years, and its temperature is 3580 K, cooler than the Sun's. One planet is known to orbit this star.

That planet, TOI-3785 b, was discovered in 2023 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. It is a Jupiter-like planet, a size class that exceeds four times Earth's radius. Its reported radius estimate is 5.14 Earth radii, larger than Earth's. Its reported mass estimate is 15 Earth masses, also larger than Earth's. Its mean density is 0.607 g/cm³, 0.11 times Earth's.

TOI-3785 b completes one orbit in 4.67 days.
