TOI-1648 b: A Neptune-Like World Around a Cool Dwarf Star
TOI-1648 is a star located 228 light-years away. It has one known planet. The star's reported mass estimate is 0.83 solar masses, smaller than the Sun's, and its reported radius estimate is 0.81 solar radii, also smaller than the Sun's. Its reported temperature is 4850 K, cooler than the Sun's, and its age is 5.7 billion years.
The planet TOI-1648 b is Neptune-like, discovered by transit in 2025. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-1648 b has a radius of 2.54 Earth radii, larger than Earth's, and a mass of 7.4 Earth masses, also larger than Earth's. Its mean density is 2.49 g/cm³, 0.452 times Earth's. The planet completes one orbit every 7.33 days.
