433 eros hitting earth
Regolith of Eros, seen during NEAR's descent; area shown is about 12 meters (40 feet) across, Orbital diagram of Eros with locations on 7 May 2013, Orbital diagram of Eros with locations on 1 January 2018, Six different views of Eros in approximate natural color from NEAR-Shoemaker in February 2000, This article is about the asteroid. «The Use of Asteroids for Determinations of Masses and Other Fundamental Constants». It was named after the Greek god of love, Eros (Greek Ἔρως). La superficie, de color marrón dorado, aparece en las fotografías llena de cráteres. ... NASA believes any space rock bigger than 82ft (25m) across is big enough to survive hitting Earth's atmosphere. [6] La misma noche, Auguste Honoré Charlois (1864-1910) desde el observatorio de Niza, Francia, tomó imágenes de Eros. [8], Eros fue descubierto el 13 de agosto de 1898 por Gustav Witt desde el observatorio Urania de Berlín, Alemania,[9] como un objeto de la undécima magnitud mientras hacía mediciones astrométricas precisas de la posición del asteroide (185) Eunike. Witt's discovery was the accidental byproduct of a two-hour photographic exposure he conducted of a different asteroid: 185 Eunike. An asteroid 13 kilometers across coming in at that speed would go right through the earth's crust and into the mantle, which we can't even drill down to yet, doing untold damage. La NASA estudia Eros amb la sonda NEAR Shoemaker llançada el 17 de febrer de 1996. You are confusing two different stories and dates. 433 Eros is the first Near-Earth asteroid (NEA) that was found. [12] Fue el primer asteroide conocido que cruza la órbita de la Tierra. La sonda siguió transmitiendo datos desde la superficie del asteroide hasta el 28 de febrero de 2001. An analysis of crater densities over the surface indicates that the areas with lower crater density are within 9 kilometers of the impact point. Some of the lower density areas were found on the opposite side of the asteroid but still within 9 kilometers. [16] (The crater involved was proposed to be named "Shoemaker", but is not recognized as such by the International Astronomical Union (IAU), and has been formally designated Charlois Regio.) It is an S-type asteroid about 13 × 13 × 33 km in size, the second-biggest near-Earth asteroid (NEA) after 1036 Ganymed.It belongs to the Amors.It is the first asteroid that was known to cross inside the orbit of Mars. Tiene una excentricidad de 0,2226 y una inclinación orbital de 10,83°. An asteroid has to hit earth at at least seven miles per second, the earth's escape velocity, and also the velocity of anything hitting it from the outside. It rotates once every 5.27 hours. Mide 33 km de un extremo al otro. A 433 Eros az elsőnek felfedezett (és az 1036 Ganymed után a második legnagyobb) földsúroló kisbolygó, mérete körülbelül 13 × 13 × 33 km.A kisbolygók róla elnevezett Amor-családjának (más elnevezéssel Apolló-Ámor családjának) a tagja. El asteroide apareció en una placa fotográfica de dos horas de exposición centrada en la estrella Beta Aquarii. Tiene un perihelio de 1,1 UA, distancia que lo aproxima periódicamente a la Tierra, y es, por tanto, un asteroide próximo a la Tierra (NEA). Ostro, S. J., Rosema, K. D.; Jurgens, R. F. (1990). It was the first asteroid orbited by an Earth probe (in 2000). Es el segundo asteroide cercano a la Tierra en tamaño después de Ganimedes. [6][7] Fue el primer asteroide en torno al cual ha orbitado y sobre el que se ha posado una sonda espacial: la NEAR-Shoemaker de la NASA entró en órbita el 14 de febrero de 2000 y aterrizó el 12 de febrero de 2001, donde hizo un análisis químico de la superficie. Asteroid 433 Eros is the second largest member of the near-Earth population and also one of the most elongated. Learn more on EarthSky. Under this condition, the asteroid actually appears to stop, but unlike the normal condition for a body in heliocentric conjunction with Earth, its retrograde motion is very small. But it will miss Earth. On January 31, 2012, Eros is expected to pass Earth at 0.1787 AU (26.8 million kilometers). Tiene un perihelio de 1,1 UA, distancia que lo aproxima periódicamente a la Tierra, y es, por tanto, un asteroide próximo a la Tierra (NEA). With current detection Eros will hit earth in 30 years. Asteroid 433 Eros passed closer to Earth on January 31, 2012 than it had since 1975. Eros's surface gravity varies greatly because Eros is not a sphere but an elongated peanut-shaped (or potato- or shoe-shaped) object. As part of its Sentry monitoring system, NASA lists asteroids that pose some risk, however small, of hitting the Earth in the next 100 years. Eros's density is 2.67 g/cm3, about the same as the density of Earth's crust. This event may also be responsible for the 40 percent of the Erotian surface that is devoid of craters smaller than 0.5 kilometers across. On Tuesday, January 31, asteroid 433 Eros will come closer to Earth than it has in 37 years, traveling across the night sky in the constellations Leo, Sextans and Hydra. Tiene una forma extremadamente alargada, similar a un cacahuete. Sin embargo, Charlois publicó los datos unos días después de Witt. A shaded-relief map of a surface cratering simulation of near-Earth asteroid 433 Eros, color-coded according to surface elevation (blue = -125 meters, pink = +125 meters). «Asteroide pasará cerca de la Tierra este martes», https://es.wikipedia.org/w/index.php?title=(433)_Eros&oldid=120780900, Objetos astronómicos descubiertos en 1898, Objetos astronómicos visitados por sondas espaciales, Objetos astronómicos descubiertos por Carl Gustav Witt, Wikipedia:Artículos con datos por trasladar a Wikidata, Wikipedia:Artículos destacados en la Wikipedia en italiano, Wikipedia:Artículos con identificadores VIAF, Wikipedia:Artículos con identificadores GND, Wikipedia:Artículos con identificadores LCCN, Wikiproyecto:Asteroides/Artículos de asteroides, Licencia Creative Commons Atribución Compartir Igual 3.0. Eros orbita a una distancia media del Sol de 1,458 ua, pudiendo alejarse hasta 1,783 ua y acercarse hasta 1,133 ua. Visited by the NEAR Shoemaker space probe in 1998, it became the first asteroid ever studied from orbit. 433 Eros live position and data. A suitable analogy would be the distance from the top centre of a bun to the bottom centre as compared to the distance from the top centre to a point on the bun's circumference: top-to-bottom is a longer distance than top-to-periphery when measured along the surface but shorter than it in direct straight-line terms. [9] No obstante, la causa del retraso fue debida a un problema técnico del telescopio que había fallado en la anulación del efecto del movimiento de la Tierra y produjo una imagen menos nítida. Only the Earth-crosser 1620 Geographos, roughly a tenth the size of Eros, is known to be more elongated (Ostro et al.1995). 433 Eros was discovered on Aug. 13, 1898 by Gustav Witt, director of the Urania observatory in Berlin, and independently on the same day by Auguste H.P. Nighttime measurements fall near −150 °C (123 K). Much of our current knowledge Su masa es de 6,687×1015 kg,[2] la diezmillonésima parte de la masa lunar. A good day to make history. En el año 2000, Eros fue el primer asteroide en ser orbitado por una sonda espacial, la NEAR Shoemaker, que acabó aterrizando en la superficie del asteroide el 12 de febrero de 2001 (maniobra para la cual la sonda no estaba diseñada). feature of 433 Eros is its virtual lack of any spectral heterogeneity. (433) Eros es un asteroide que forma parte de los asteroides Amor y fue descubierto por Carl Gustav Witt (1866-1946) en 1898. 433 Eros.
