From the Encyclopaedia Britannica, 17th Edition, 2093: Icarus()
Minor planet 1566. Had the most eccentric elliptic orbit of all the known asteroids (e = 0.83), the smallest semimajor axis (a = 1.08) and passed closest to the sun (28,000,000 kilometers). It was discovered by Walter Baade of Mt. Palomar Observatory in 1949. Its orbit extended from beyond Mars’s to within Mercury’s; it could approach to within 6,400,000 kilometers of the Earth. Radar observations showed it to have a diameter of about 0.8 kilometer and a rotation period of about 2.5 hours. The unusual orbit attracted only minor interest until June 2017, when Icarus suddenly began emitting a plume of gas and dust. Since it was presumably a typical rocky Apollo asteroid, this evolution into a cometary object excited the astronomical world. The oddity became of intense concern when calculations in October 2017 showed that the momentum transferred to the escaping cometary tail was altering the orbit of Icarus. This orbital perturbation could, within a few years, cause a portion of the comet to collide with the Earth. Impact of the tenuous gas would be harmless. But the head of the comet Icarus was by then obscured, and some conjectured that a solid core could remain, in which case …
Icarus
In Greek legend, the son of Daedalus. After Daedalus, an architect and sculptor, built the labyrinth for King Minos of Crete, he fell out of favor with the king. He fashioned wings of wax and feathers for himself and Icarus, and escaped to Sicily. Icarus, however, flew too near the sun and his wings melted; he fell into the sea and drowned. The island on which his body was washed ashore was later named Icaria. The legend is often invoked as a symbol of man’s quest for knowledge and fresh horizons, whatever the cost. Icarus was invoked in van Hoven’s masterwork, Icarus Descending (2017), as an emblem for the decline of Western cultural eminence …
