Green comet set to fly by Earth first time in 50,000 years

A comet from the outer solar system will pass by our planetary neighbourhood for the first time in 50,000 years.

Today (January 12), the comet, formally known as C/2022 E3 (ZTF), will make its closest approach to the sun and may be bright enough to be seen with binoculars and a telescope.

C/2022 E3 (ZTF) may even become visible to the naked eye in dark skies at the end of January, depending on how bright it gets in the upcoming weeks.

After February, there won’t be another chance to view Comet C/2022 E3 (ZTF) for a very long time as its orbital period is 50,000 years.
