    100000 Astronautica (provisional designation: 1982 SH1) is an asteroid from the inner asteroid belt discovered on September 28, 1982 by James B. Gibson at Palomar Observatory.[2] It has an absolute magnitude of 16.7, and an orbital period of 960.205 days.[3]

    This asteroid was named in October, 2007 by the International Astronomical Union's Committee on Small Body Nomenclature to recognize the fiftieth anniversary of the start of the Space Age, as marked by the launch of the Soviet Sputnik spacecraft into orbit on October 4, 1957. The number 100,000 is significant because it marks the altitude in meters where outer space begins, as delineated by the Kármán line established by the Fédération Aéronautique Internationale.[4] The name 'Astronautica' is Latin for 'star sailor'.[5]
