It is a quasi-satellite of Earth until around 2600. On 14 April 2004 (with less than a 1-day observation arc), the Sentry Risk Table showed 180 virtual impactors. It was removed from the Sentry Risk Table 2 days later on 16 April 2004. Cardea now has a well determined orbit with an observation arc of 12 years. Discovery and naming This asteroid was discovered on 13 April 2004 by the Lincoln Near-Earth Asteroid Research project near Socorro, New Mexico and given the provisional designation . Following the naming of 524522 Zoozve, a quasi-satellite of Venus, Radiolab and the International Astronomical Union held a public naming campaign for this quasi-satellite from June to September 2024. Seven finalist names were revealed in December 2024, with the names being Bakunawa, Cardea, Ehaema, Enkidu, Ótr, Tarriaksuk, and Tecc ...

Lincoln Near-Earth Asteroid Research
The Lincoln Near-Earth Asteroid Research (LINEAR) project is a collaboration of the United States Air Force, NASA, and the Massachusetts Institute of Technology's Lincoln Laboratory for the systematic detection and tracking of near-Earth objects. LINEAR was responsible for the majority of asteroid discoveries from 1998 until it was overtaken by the Catalina Sky Survey in 2005. , LINEAR had detected 231,082 new small Solar System bodies, of which at least 2,423 were near-Earth asteroids and 279 were comets. The instruments used by the LINEAR program are located at Lincoln Laboratory's Experimental Test Site (ETS) on the White Sands Missile Range (WSMR) near Socorro, New Mexico. History In the late 1970s, the ''Lincoln Laboratory's Experimental Test Site'' facility (observatory code 704) was built at White Sands Missile Range. The project's prototype used low-light video cameras. In 1994 a new proposal was made for automated detection of asteroids, this time using newer digi ...

Tarriaksuk
In Inuit mythology the Tariaksuq (Taqriaqsuk, Taqriaqsuq, Tarriaksuk, Tarriaksuq, Tarriassuk, Tarriassuq; (plural) "Shadow-People", Taqriaqsuit, Tariaksuit, Tarriaksuit, Tarriassuit) is a humanoid creature associated with shadows, invisibility and obscurity. It is said that, for the most part, they are the same as any other human being. They have houses, families, weapons, tools, and more. Where they deviate from normal people, however, is that they are not visible by looking straight at them. In looking directly at them, they either disappear into the separate world which they occupy, apart from our own, or they are only seen for the shadow they cast. They only become visible if they are killed, and they are said to appear as half-man-half-caribou creatures. Aside from the strange condition of their visibility, it is also known that they can only catch prey while hunting it on foot.

Ótr
In Norse mythology, Otr (Old Norse: ; alternately: Ott, Oter, Ottar, Ottarr, Otter) is a Norse dwarves, dwarf. He is the son of the king Hreidmar and the brother of Fafnir and Regin. According to the Prose Edda, Otr could Shapeshifting#Norse, change into any form and used to spend his days in the shape of an otter, greedily eating fish. In this form, he was slain by Loki, who wanted his pelt. Initially, Hreiðmarr demanded a life for a life, but with the argument that the murder had been an accident when no one involved knew that Otr was a dwarf, he settled for receiving a large weregild for Otr's death, namely to fill Otr's skin with yellow gold and to then cover it entirely with red gold. When the skin was covered, one whisker still protruded, forcing Loki to give up the ring Andvaranaut to hide it. The ring had been stolen from, and cursed by, the dwarf Andvari. It is suggested that this story was meant to show the benefits of not only adhering to the letter of the law (repaymen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enkidu
Enkidu ( ''EN.KI.DU10'') was a legendary figure in Mesopotamian mythology, ancient Mesopotamian mythology, wartime comrade and friend of Gilgamesh, king of Uruk. Their exploits were composed in Sumerian language, Sumerian poems and in the Akkadian language, Akkadian ''Epic of Gilgamesh'', written during the 2nd millennium BCE, 2nd millennium BC. He is the oldest literary representation of the wild man, a recurrent motif in artistic representations in Mesopotamia and in Ancient Near East literature. The apparition of Enkidu as a primitive man seems to be a potential parallel of the Kassites, Old Babylonian version (1300–1000 BC), in which he was depicted as a servant-warrior in the Sumerian poems. There have been suggestions that he may be the "bull-man" shown in Mesopotamian art, having the head, arms, and body of a man, and the horns, ears, tail and legs of a bull. Thereafter a series of interactions with humans and human ways bring him closer to civilization, culminating i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estonian Mythology
Estonian mythology is a complex of myths belonging to the Estonian folk heritage and literary mythology. Information about the pre-Christian and medieval Estonian mythology is scattered in historical chronicles, travellers' accounts and in ecclesiastical registers. Systematic recordings of Estonian folklore started in the 19th century.

Estonian mythology in old chronicles According to the Chronicle of Henry of Livonia in 1225 the Estonians disinterred the enemy's dead and burned them. It is thought that cremation was believed to speed up the dead person's journey to the afterlife and by cremation the dead would not become earthbound spirits which were thought to be dangerous to the living. Henry of Livonia also describes in his chronicle an Estonian legend originating in Virumaa in northe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bakunawa
The Bakunawa, also called the Philippine moon-eating dragon, the Philippine moon dragon, moon dragon, or the moon-eating dragon, is a serpent, that looks like a Dragon in Philippine mythology. It is believed to be the cause of eclipses, earthquakes, rains, and wind. The movements of the Bakunawa served as a geomantic calendar system for ancient Filipinos and were part of the rituals of the '' babaylan'' priestess. It is usually depicted with a characteristic looped tail and a single horn on the nose. It was believed to inhabit either the sky or the underworld. Due to increasing trade contacts with South Asia and the Indianization of Southeast Asia, the Bakunawa later became syncretized with the Nāga, Rahu, and Ketu of Hindu- Buddhist mythology. Etymology Bakunawa is believed to be originally a compound word meaning "bent snake", from Proto-Western-Malayo-Polynesian ''*ba(ŋ)kuq'' ("bent", "curved") and ''*sawa'' ("large snake", "python").
