This newly discovered planet, named TOI-6894b, blocks 17 percent of the star’s light, indicating the planet is fairly large. “This discovery will be a cornerstone for understanding the extremes of giant planet formation,” Bryant said. TOI-6894 is nearly 40 percent smaller than the previous record for the smallest star with a planet of this size. But if the mass of the star is small, the mass of its protoplanetary disk tends to be small as well. However, the observed disk surrounding the star TOI-6894 contains only 58 times the mass of the Earth at most.
