TOI-942: A Young K-Type Star With Two Known Planets
TOI-942 is a K2.5 V star located 498 light-years away. Its mass is 0.88 solar masses, its radius is 0.893 solar radii, and its temperature is 4970 K, all three lower than the Sun's corresponding values. At 0.05 billion years old, it is a very young star. Two planets are known to orbit it.
TOI-942 b is Neptune-like. Its radius is 3.89 Earth radii, and it completes an orbit in 4.32 days. TOI-942 c is Jupiter-like in size classification, with a radius of 4.67 Earth radii and an orbital period of 10.2 days. Both were discovered in 2020 by the transit method. Each planet's radius is larger than Earth's, and among the listed planets TOI-942 b has the shortest year and the smallest radius while TOI-942 c has the longest year and the largest radius.
