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
Arrow to the Sun of men. Arrow to the Sun Arrow to the Sun is a 1973 short film and a 1974 book, both by Gerald McDermott. The book was printed in gouache and ink, and won the 1975 Caldecott Medal for illustration. Both media are a retelling of a Pueblo tale, specifically an Acoma Pueblo tale, in which a mysterious boy seeks his father. The Boy (who does not have a name) is the son of the Sun lord, who sends the spark of life into a maiden of the Pueblo. He is ridiculed by the other boys because he has no father.
