In a rare celestial event, a green comet is set to make its closest approach to Earth since the Stone Age.

The comet, known as C/2020 F8 SWAN, was first spotted in March of this year and will make its closest approach to Earth on May 18th. This is the first time it has been visible from Earth since the Stone Age.

Astronomers have been tracking the comet for weeks, and it is now bright enough to be seen with the naked eye. It will be visible in the night sky for the next few weeks, and is expected to reach its peak brightness on May 23rd.

The comet is expected to make its closest approach to Earth on May 24th, when it will be just over 7 million miles away. This is the closest the comet has been to Earth in over 50,000 years.

For those interested in catching a glimpse of the comet, Fox Weather has some tips on how to watch it. The comet will be visible in the Northern Hemisphere, and is best viewed in a dark sky free of light pollution.

CNN also has a guide on how to take pictures of the comet. They recommend using a camera with a long exposure mode and a wide-angle lens.

The green comet is a rare event, and one that won’t be seen again for thousands of years. But those interested in catching a glimpse of this remarkable celestial event still have time to do so.
