In this article, we’ll provide you with all the essential details about this mesmerizing event, from its discovery to the best times and locations to observe it.

Discovery and Characteristics

  • C/2023 G2, dubbed the “Green Comet,” was first detected by astronomers using advanced telescopes on July 31, 2023.
  • The green hue of the comet is caused by diatomic carbon (C2) molecules fluorescing in the sunlight, creating a stunning emerald glow.
  • It is estimated that the comet is about 2.4 miles (4 kilometers) in diameter, making it a substantial celestial object.

Closest Approach

  • The Green Comet is currently making its closest approach to Earth, coming within approximately 60 million miles (97 million kilometers) of our planet.
  • This proximity allows skywatchers in both the Northern and Southern Hemispheres to witness its brilliance.
  • The best time to view the comet is during the pre-dawn hours when the skies are darkest.

Visibility and Location

  • To observe the Green Comet, you’ll need binoculars or a small telescope for the best viewing experience.
  • Find a location away from light pollution, such as a rural area or a high vantage point.
  • Look towards the east-northeastern horizon in the early morning hours.

Safety Tips

  • When observing celestial objects, remember to protect your eyes by using proper eye protection, such as eclipse glasses or specially designed solar filters for telescopes.
  • Be patient, as it may take some time for your eyes to adjust to the darkness.

Comet’s Path

  • The Green Comet is on a trajectory that will eventually take it back to the outer reaches of our solar system, where it will disappear from view.
  • This rare encounter with a green-hued comet is a once-in-a-lifetime event for many skywatchers.


C/2023 G2, the Green Comet, is giving us a remarkable opportunity to witness the beauty of the cosmos up close.
