Kepler-11 Has Six Small Planets

Six Small Planets Orbiting a Sun-like Star Amaze Astronomers, UCSC

"A remarkable planetary system discovered by NASA's Kepler mission has six planets around a Sun-like star, including five small planets in tightly packed orbits. Astronomers at the University of California, Santa Cruz, and their coauthors analyzed the orbital dynamics of the system, determined the sizes and masses of the planets, and figured out their likely compositions -- all based on Kepler's measurements of the changing brightness of the host star (called Kepler-11) as the planets passed in front of it."

"Few stars are known to have more than one transiting planet, and Kepler-11 is the first known star to have more than three," said Lissauer. "So we know that systems like this are not common. There's certainly far fewer than one percent of stars that have systems like Kepler-11. But whether it's one in a thousand, one in ten thousand or one in a million, that we don't know, because we only have observed one of them."
