Asteroid Terrestrial-impact Last Alert System
The Asteroid Terrestrial-impact Last Alert System (ATLAS) is a robotic astronomical survey and early warning system optimized for detecting smaller near-Earth objects a few weeks to days before they Impact event, impact Earth. Funded by NASA, and developed and operated by the University of Hawaii's Institute for Astronomy (Hawaii), Institute for Astronomy, the system currently has four 0.5-meter telescopes. Two are located apart in the Hawaiian islands, at Haleakala Observatory, Haleakala (ATLAS–HKO, observatory code IAU code#T05, T05) and Mauna Loa Observatory, Mauna Loa (ATLAS–MLO, observatory code IAU code#T08, T08) observatories, one is located at the South African Astronomical Observatory, Sutherland Observatory (ATLAS–SAAO, observatory code IAU code#M22, M22) in South Africa, one is at the El Sauce Observatory in Rio Hurtado (Chile) (ATLAS–CHL, observatory code IAU code#W68, W68). The newest at Teide Observatory (ATLAS-Teide) was commissioned in February 2025, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C2022 R2 2022-10-06 Image ZTF-sso-622-zr-size-7
C, or c, is the third letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C/2023 E1 (ATLAS)
C/2023 E1 (ATLAS) is a periodic comet with an orbital period of 85 years. It fits the classical definition of a Halley-type comet with an orbital period of between 20 and 200 years. The comet was discovered on 1 March 2023 by ATLAS South Africa. Upon discovery, the comet had an apparent magnitude of about 19 and had a very condensed coma. The comet was subsequently found in images obtained by other observatories back on 25 December 2022. The comet brightened in late June to a magnitude of +10, and became visible in small telescopes and binoculars. At that time, it was located high in the northern skies, in the constellation of Ursa Minor. It passed its perihelion on 1 July and reached an apparent magnitude between 8 and 9. The comet had a greenish coma and a faint narrow ion tail. On July 8 it passed 9 degrees from the north celestial pole. The closest approach to Earth was on 18 August, at a distance of 0.375 AU. The comet seems to be in a 2:1 orbital resonance with Neptune ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
