rare comet

Recently, the scientists of NASA discovered a rare comet U1 NEOWISE, approaching towards a preferably visible position from earth. The comet is a rare one and can be seen sometime during this week. The comet will be visible with naked eyes. All you will need is just a binocular.

The NEO manager of NASA center, Paul Chodas says, ” Comet C/2016 U1 NEOWISE has a very good chance of becoming visible. You can watch the comet through a pair of binocular. Although, the brightness of the comet can’t be detected since comets have a brightness which fluctuates extremely.”

The comet U1 NEOWISE is traveling from Northern hemisphere to Southern Hemisphere and will be visible in the Southern Hemisphere with a short period of time, during dawn. The Comet U1 NEOWISE is moving southwards and soon will reach nearest to the Sun. The scientists are expecting the comet to enter the orbit of Mercury, by January 14, 2017, which is only 11 days from today. Hence, it is advised to all sky watchers, to keep their binoculars ready next week.

NEO stands for Near Earth Objects. The NEOWISE research project, have also discovered some other celestial bodies, which are slowly approaching the orbit of Jupiter and will enter the Jupiter’s orbit in 4.9 earth-years. Since Jupiter is just second from the Earth’s position in the solar system, some of these celestial bodies can even approach earth’s orbit. However, the NASA scientists are trying their level best to direct the celestial bodies towards the outer solar system.

The comet U1 NEOWISE will be visible to the sky watchers, through a binocular, but it will be wrong to predict that the comet is nearest to the earth, because scientists have put forward their statement with confidence that the comet U1 NEOWISE is not a threat to our planet.

Near-Earth objects (NEOs) absorb most of the light that falls on them and re-emit that energy at infrared wavelengths. This enables NEOWISE’s infrared detectors to study both dark and light-colored NEOs with nearly equal clarity and sensitivity.

“These are quite dark objects,” said NEOWISE team member Joseph Masiero, “Think of new asphalt on streets; these objects would look like charcoal, or in some cases are even darker than that.”

NEOWISE data have been used to measure the size of each near-Earth object it observes. Thirty-one asteroids that NEOWISE has discovered pass within about 20 lunar distances from Earth’s orbit, and 19 are more than 460 feet (140 meters) in size but reflect less than 10 percent of the sunlight that falls on them.

 The Wide-field Infrared Survey Explorer (WISE) has completed its seventh year in space after being launched on Dec. 14, 2009.
