Wolf Cukier, 17, of Scarsdale, N.Y., had wrapped up his junior year of high school when he headed off to intern in the summer at NASA’s Goddard Space Flight Center in Greenbelt, Md., where he discovered a planet orbiting two stars.
The planet, now known as TOI 1338 b, is nearly seven times as large as Earth and has two stars — one that’s about 10 percent more massive than our sun and another only a third of the sun’s mass and less bright, according to NASA.
