2018 GE3 (original) (raw)
2018 GE3 is a sub-kilometer asteroid on a highly eccentric orbit, classified as a near-Earth object of the Apollo group, approximately 48–110 meters (160–360 feet) in diameter. It was first observed on 14 April 2018, by astronomers with the Catalina Sky Survey one day prior to its sub-lunar close encounter with Earth at 0.5 lunar distance. It is one of the largest known asteroids (possibly the largest) in observational history to ever pass that close to Earth (also see ).

(en) 2018 GE3 è un asteroide near-Earth del diametro compreso tra i 48 e 110 metri in base alla quantità di luce riflessa. È stato scoperto il 14 aprile 2018 dal progetto di ricerca del Catalina Sky Survey ed il 17 aprile è passato a soli 192200 km dalla superficie terrestre. Presenta un'orbita caratterizzata da un semiasse maggiore pari a 1,8279468 au e da un'eccentricità di 0,8272085, inclinata di 9,03370° rispetto all'eclittica. Per dimensioni, al momento del passaggio, divenne il sesto oggetto più massiccio di cui sia noto il passaggio a meno di 1 distanza lunare. (it) 2018 GE3 — астероид, пересекающий орбиты Меркурия, Венеры, Земли и Марса. Относится к группе аполлонов. При открытии получил предварительное обозначение ZG009C1. Был обнаружен 14 апреля 2018 года в созвездии Весы небесным обзором Catalina Sky Survey (штат Аризона, США). Блеск при открытии составил +15,6m. В афелии удаляется от Солнца на 506 млн км, в перигелии приближается к нему на 48 млн км (Меркурий в афелии находится в 69,8 млн км от Солнца). Сближение с Землёй состоялось 15 апреля 2018 года в 6:41 UTC, расстояние — 193 тыс. км (0,52 расстояния до Луны), относительная скорость 29,585 км/c (106 505 км/ч). Диаметр астероида может достигать 111 м. (ru) |
