Skywatchers: The Green Comet is back after 50,000 years 


Comet C/2022 E3 (ZTF), more commonly known as the Green Comet, will make its closest approach to Earth on February 1 and will still be highly visible for the next 10 days as it heads towards Mars.

The dark green comet was discovered and named just last year on March 2, 2022. It has been moving closer to us ever since.

This newly discovered comet’s orbit has taken it far from Earth. And now it’s back for the first time in 50,000 years. Astronomers say that the comet was last visible in the night sky during the Stone Age.

On January 12 it was at its closest point to the Sun. It will be closest to Earth and at its peak brightness on February 1.  And this week is when it’s likely to spot it with the naked eye from Earth.

But if you want to be certain you get a view of the Green Comet’s tail use a telescope.



What Is the Green Comet?

Comets are relatively small space rocks. They consist largely of ice and dust. They orbit the Sun from the outer parts of the solar system to the inner solar system. And when they move to the inner areas, they can become visible from Earth.
