On February 1st, the comet C/2022 E3 (ZTF) made its 42 million-kilometre approach to Earth, visible with either a telescope, binoculars or even the naked eye if the sky was starry.
This rare green-tailed celestial body "passed" Earth approximately 50,000 years ago, during the Middle Paleolithic period.
Meanwhile, almost every night, I stare at another celestial body, the Moon, which is 4.51 billion years old.
