[space] The Uncensored Guide To ‘Oumuamua, Aliens, And That Harvard Astronomer … A rational look at the interstellar visitor ʻOumuamua. ‘When it made its closest approach to the Sun, it was moving incredibly fast: up to 88 km/s, or three times the speed that Earth orbits the Sun. But we were lucky to image it at all. It was small (only about 100 meters long), faint, and very red in color, similar to the Trojan asteroids we see in orbit around Jupiter. Its color is different from the icy bodies we know of, failing to match up with comets, Kuiper belt objects, or even centaurs, and follow-up observations revealed a certain amount of boring-ness to ‘Oumuamua, as it displayed no molecular or atomic absorption or emission features.’
