CABO CA\u00d1AVERAL.-<\/strong> Un cometa se acerca a la Tierra por primera vez en 50 mil a\u00f1os.<\/p>\n

La bola de nieve sucia nos visit\u00f3 por \u00faltima vez en tiempos de los Neandertales, seg\u00fan la NASA. Se acercar\u00e1 a 42 millones de kil\u00f3metros (26 millones de millas) el mi\u00e9rcoles antes de alejarse nuevamente para no regresar, probablemente, en millones de a\u00f1os.<\/p>\n

Descubierto hace menos de un a\u00f1o, el inofensivo cometa verde es visible en el cielo norte\u00f1o nocturno con binoculares o peque\u00f1os telescopios, y posiblemente a simple vista en los rincones m\u00e1s oscuros del hemisferio norte. Se volver\u00e1 m\u00e1s brillante a medida que se acerca y se alza m\u00e1s sobre el horizonte hasta el fin de enero. Las mejores horas para verlo ser\u00e1n poco antes del amanecer. Para el 10 de febrero estar\u00e1 cerca de Marte, una buena indicaci\u00f3n.<\/p>\n

Solo habr\u00e1 que mirar hacia el noroeste, especialmente antes del amanecer. Ser\u00e1 visible sin prism\u00e1ticos ni telescopio, aunque de este modo es posible que solo se aprecie una mancha en el cielo. Es recomendable estar en un lugar donde haya poca luz de la ciudad.<\/p>\n

Los aficionados a la astronom\u00eda del hemisferio sur deber\u00e1n esperar al mes pr\u00f3ximo para poder vislumbrarlo.<\/p>\n

Si bien muchos cometas han adornado el cielo el a\u00f1o pasado, \u201ceste parece ser un poco m\u00e1s grande y, por lo tanto, un poco m\u00e1s brillante y se acerca un poco m\u00e1s a la \u00f3rbita de la Tierra, dijo el gur\u00fa sobre cometas y asteroides de la NASA, Paul Chodas.<\/p>\n

El tinte verde proviene del carbono en la nube de gas que rodea el n\u00facleo. El cometa fue descubierto en marzo del a\u00f1o pasado por los astr\u00f3nomos que utilizan la Zwicky Transient Facility, una c\u00e1mara de campo amplio del Observatorio Palomar de Caltech. Su nombre oficial es C\/2022 E3 (ZTF).<\/p>\n

Pasar\u00e1 el mi\u00e9rcoles entre las \u00f3rbitas de la Tierra y Marte a una velocidad relativa de 207 mil km\/hora (128 mil 500 mph). Se calcula que su n\u00facleo tiene un di\u00e1metro de mil 600 metros (una milla) y sus colas se extienden millones de kil\u00f3metros (millas).<\/p>\n

No se prev\u00e9 que esa tan brillante como el Neowise de 2020 o el Hale Bopp y el Hyakutake de mediados a fines de la d\u00e9cada de 1990. Pero \u201cser\u00e1 brillante en virtud de su paso cerca de la Tierra… lo que permitir\u00e1 a los cient\u00edficos hacer m\u00e1s experimentos y a la gente ver un hermoso cometa\u201d, dijo Karen Meech, astr\u00f3noma de la Universidad de Haw\u00e1i, en un correo electr\u00f3nico.<\/p>\n","protected":false},"excerpt":{"rendered":"
