Astronomers studying data from NASA’s retired Kepler space telescope discovered a new system of seven “scorching” planets orbiting a distant star that is bigger and hotter than the sun, the space agency said Thursday.
NASA described the newly found planets as “sweltering” and “bathed” in radiant heat emitted by the host star that was described as “sun-like.” That star is 10% larger and 5% “hotter than the sun,” NASA said, and there is more heat per area from that star than any planet in our solar system experiences.
All of the planets are larger than Earth, with the two inner planets just slightly larger and the other five planets even bigger, about twice the size of Earth. The inner planets are “probably rocky and may have thin atmospheres,” NASA said, while the five outer planets are expected to have thick atmospheres.
