TOI-757 and Its Neptune-Like Planet
TOI-757 is a K0 V star located 197 light-years away. Its reported mass is 0.8 solar masses, its radius is 0.78 solar radii, and its temperature is 5280 K. The star is estimated to be 7.5 billion years old. One planet is known to orbit it.
That planet is TOI-757 b, a Neptune-like world discovered by the transit method in 2024. In this method, a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-757 b has a mass of 10.5 Earth masses and a radius of 2.5 Earth radii, and it completes one orbit every 17.5 days. Its mean density is 3.7 g/cm³, which is 0.672 times Earth's density.
