Planet the Drake equation, which estimates the number of intelligent, communicating civilizations that exist in the Milky Way. There are exoplanets that are much closer to their parent star than any planet in the Solar System is to the Sun, and there are also exoplanets that are much farther from their star. Mercury, the closest planet to the Sun at 0.4 AU, takes 88 days for an orbit, but the shortest known orbits for exoplanets take only a few hours, e.g. Kepler-70b. The Kepler-11 system has five of its planets in shorter orbits than Mercury's, all of them much more massive
A Beautiful Planet star about half the size and mass of the Sun which lies in the direction of the constellation Cygnus, about 500 light-years away. The number "186" in the planet's name refers to the order in which its planetary system was discovered while scientists processed all of the data produced by the Kepler Space Telescope, and the planet itself is designated "f" because the first planet to be discovered in the system is designated as planet "b," the second discovered is "c," etc., and it was the fifth planet to be discovered. Even though the idea of interstellar travel to another
