This is the only green comet that visits Earth
A green comet named C/2022 E3 is "closing in" on Earth, likely passing its perigee at a relative speed of more than 200,000 kilometers per hour. On February 2, the comet passed its orbital perigee, just 0.28 astronomical units, or about 42.5 million kilometers, from Earth. It is also the brightest comet known to be observed by Earth this year.
