CEDAR RAPIDS, Iowa (KCRG) - There are many sights in the nighttime sky that we can see only for a short period of time each year. However, when a comet approaches, it can been seen for many nights in a row. Get set as we have a comet coming into our sky.
Comet 46P/Wirtanen is moving in the general direction of the Earth. This will be visible with the naked eye, without the aid of binoculars or a telescope. As we approach the middle of December, the comet will be about seven million miles away from Earth.
One issue (other than needing a clear sky) is the full moon. That could make it harder to see without some mechanical aid.
Comet 46P/Wirtanen passes through our solar system about every five-and-a-half years.
