- Der Asteroid 2018 AH ist ein erdnahes Objekt, das am 3. Januar 2018 entdeckt wurde, nachdem es bereits am 2. Januar 2018 um 4:25 Uhr (TDB) die Erde innerhalb der Mondbahn passiert hatte. Der Durchmesser wird mit 84 bis 190 m angegeben. Die Geschwindigkeit betrug bei der größten Annäherung 13,8 km/s. (de)
- 2018 AH is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group, approximately 100 m (300 ft) in diameter. It was first observed on 4 January 2018, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on Mauna Loa and quickly followed-up by many other surveys, with precovery observations found from Pan-STARRS and PTF from the day previous. It is the largest known asteroid to pass so close to Earth (0.001985 AU (297,000 km; 184,500 mi)) since 2002 JE9 in 1971, and until 2001 WN5 in 2028, although it was only discovered two days after its closest approach on 2 January 2018, at 04:25 UTC. The Tunguska asteroid was likely of a similar size, if not slightly smaller. Before being recovered on 4 January 2022 11:49 UTC at an Earth distance of 9.8 million km, the asteroid only had an observation arc of 46 days and had not been observed since February 2018. Being a short arc object that had not been observed for years generated an uncertainty that is relatively large. Between 24-31 December 2021 it was only known to make an Earth approach of between 1-8 million km. As it came to perihelion on 3 December 2021, it was approaching from the direction of the Sun. (en)
- 2018 AH è la designazione data all'asteroide di circa 81 m che il 2 gennaio 2018 transitò a poco più di 300000 km dalla Terra, circa quattro quinti della distanza del pianeta stesso dalla Luna, diventando, per dimensioni, il secondo maggiore tra quelli transitati a meno di una distanza lunare. 2018 AH è stato scoperto solo due giorni dopo il suo massimo avvicinamento, poiché osservato dalla Terra proveniva da un punto in prossimità del Sole e quindi non visibile. Successivamente l'osservazione è potuta proseguire fin oltre meta febbraio, fornendo complessivamente, compreso una prescoperta di un giorno, un arco temporale di 46 giorni. (it)
- 2018 AH – planetoida z grupy planetoid bliskich Ziemi z grupy Apolla. Została odkryta 4 stycznia 2018 czasu UTC (3 stycznia czasu lokalnego) przez teleskop programu znajdujący się na Mauna Loa na Hawajach, dwa dni po przelocie blisko Ziemi 2 stycznia 2018 o godzinie 4:25 UTC, kiedy to minęła Ziemię w odległości 297 tysięcy kilometrów, czyli 0,77 średniej odległości Księżyca od Ziemi. Wielkość jej jest szacowana na 84–190 m. (pl)
