NASA’s TESS telescope has discovered the first planet orbiting a binary system. The researchers reported the discovery at the 235th American Astronomical Society. Since 2018, TESS has used the Ling-Sun phenomenon to discover 37 exoplanets and more than 1,500 candidate planets.
TOI 1338 b is the first planet it has discovered that moves around a binary system. It is located in the constellation of Painted Frames, 1300 light-years away. One of the two stars is slightly larger than the sun, and the other is a red dwarf star with a mass of 30% of the sun.
The distance between the two stars is relatively close, with 14.6 days around the week. TOI 1338 b is relatively distant, with a orbit of 95 days a week.
Astronomers say TOI 1338 b’s current orbit is relatively stable and won’t change for at least 10 million years, but its orbital tilt changes over time.
