Amazing Photos: Brilliant Comet 46P/Wirtanen Wows Stargazers

Astrohotographer Gerald Rhemann captured this image of Comet 46P/Wirtanen on Dec. 4, 2018 from Farm Tivoli, Namibia.

The bright-green Comet 46P/Wirtanen is visible to the naked eye in the night sky throughout the month of December 2018 as it makes a close approach to the sun. It reaches perihelion — its closest point to the sun — on Dec. 13, and it will be at its brightest on Dec. 16, the evening before it makes its closest approach to Earth.
