The comet 46P / Wirtanen, which passed every 5.4 years by the earth, was one of three comets that Carl Wirtanen was discovered in 1948 at the Lick Observatory in California. This orbit will be one of the closest comet jobs until the earth since the 1950s, according to Space.com.
Comets are "mud of ice, dust and rock". The core core of the structure is usually only a few kilometers. These cosmic phenomena have most severe swelling that have resulted from dust and iron spots that suppress comets as they are close to the sun. Currently, NASA reports that 3,535 known comets are.
The Comet 46P will probably not be a big hit according to its relatively small size, according to Space.com. It measures 0.68 kilometers in diameter, one-tenth of the size of the popular Halley's Comet. Currently, 46P is a small blue object in the night sky.
At its closest point to the earth, the comet will be 30 times the distance, the earth is away from the moon – around – 7.2 million miles – and should appear with the blood of a location with slight light pollution. The comet is in the southern sky, near the Orion constellation, according to CBC. Although it can be seen with the blood eye, the best ways to get this comet with binoculars or a telescope.
On December 12, 46P will put the worst in their operation on the sun, and it will be near the earth at 8:06 and ET on December 16, according to Space.com.
