14827 Hypnos 14827 Hypnos 14827 Hypnos, provisional designation , is a highly eccentric, sub-kilometer-sized carbonaceous asteroid that is thought to be an extinct comet. It is classified as near-Earth object and potentially hazardous asteroid of the Apollo group. The asteroid was discovered by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California on 5 May 1986. It was named after Hypnos, the Greek god of sleep. "Hypnos" orbits the Sun at a distance of 0.9–4.7 AU once every 4 years and 9 months (1,749 days). Its orbit has a high eccentricity of 0.67 and an inclination of 2°
14827 Hypnos with respect to the ecliptic. It is frequently perturbed by Jupiter. The body's observation arc begins at Anderson Mesa Station the night prior to its official discovery observation at Palomar. As a near-Earth object and potentially hazardous asteroid "Hypnos" has an Earth minimum orbital intersection distance of , which corresponds to 5.7 lunar distances. In 1958, "Hypnos" passed less than 0.03 AU from both Earth and Mars. Neither planet has been approached so closely by "Hypnos" since the 862 AD pass of Earth, or will be until the 2214 pass of Earth. It is also a Mars-crosser. "Hypnos" may be
