source link A comet will zoom past Earth Tuesday morning (March 22) in a close encounter of historic proportions.
http://penyerang.com/?p=smartwork-homework Comet P/2016 BA14, which you can see the object and its orbit, will come within 2.2 million miles (3.5 million kilometers) of the planet at about 10:30 a.m. EDT (1430 GMT) Tuesday. Only two other comets have come closer to Earth throughout recorded history — Comet D/1770 L1 (Lexell) in 1770 and C/1983 H1 (IRAS-Araki-Alcock) in 1983, NASA officials said.
get Comet Lexell’s flyby brought it within 1.4 million miles, or 2.2 million km, of Earth back in 1770. (For perspective, the moon orbits our planet at an average distance of 238,850 miles, or 384,400 km. Asteroids commonly cruise by inside the moon’s orbit, but comets are different beasts.)
essay generation problems Skywatchers shouldn’t expect P/2016 BA14 to put on a celestial show, however. The roughly 375-foot-wide (115 meters) comet is visible only with the aid of a professional-grade telescope, NASA officials said. And Earthlings have nothing to fear from the icy wanderer, either, they added.
Buy Essay Business “March 22 will be the closest Comet P/2016 BA14 gets to us for at least the next 150 years,” Paul Chodas, manager of the Center of NEO (Near-Earth Object) Studies at NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement. “Comet P/2016 BA14 is not a threat. Instead, it is an excellent opportunity for scientific advancement on the study of comets.”
make me a thesis statement Scientists think P/2016 BA14 may be a fragment of the 750-foot-wide (230 m) Comet 252P/LINEAR, which performed its own flyby early Monday morning (March 21), coming within about 3.3 million miles (5.2 million km) of Earth.
writing custom admx files “The two could be related, because their orbits are so remarkably similar,” Chodas said. “We know comets are relatively fragile things, as in 1993, when Comet Shoemaker-Levy 9 was discovered and its pieces [were] linked to a flyby of Jupiter. Perhaps during a previous pass through the inner solar system, or during a distant flyby of Jupiter, a chunk that we now know of as BA14 might have broken off of 252P.”
thesis writing companies Scientists will study the two comets using NASA’s Hubble Space Telescope and Infrared Telescope Facility, as well as other instruments, to investigate the comets’ possible relationship.
