A rare cosmic visitor, Comet C/2025 A6 (Lemmon), is on its way toward Earth this month. With an orbital period of about 1,350 years, this extraordinary comet will make a close approach that could allow it to be visible to the naked eye. Scientists anticipate a spectacular celestial show before the comet heads back into the depths of space.
**Celestial Path and Close Approach**
Comet Lemmon was first spotted on January 3 by astronomers at the Mt. Lemmon SkyCenter in Arizona. Originating from the Oort Cloud—a distant region of icy bodies at the edge of our solar system—the comet is traveling toward the Sun and Earth at nearly 209,300 km/h. It is expected to make its closest approach to Earth on October 21, coming within 56 million miles of our planet.
**A Unique Emerald Glow**
One of Comet Lemmon’s most distinctive features is its emerald-colored coma, the cloud of gas and dust surrounding the nucleus. This green glow is caused by diatomic carbon molecules—two carbon atoms bonded together—that emit bright green light when struck by sunlight. The comet also boasts a vibrant tail made up of gas, ice, and dust particles, which are pushed away by solar radiation, adding to its breathtaking appearance.
**How and When to View Comet Lemmon**
Already visible with basic stargazing equipment, Comet Lemmon is expected to brighten further in the coming weeks and may soon be seen with the naked eye. Astronomers suggest looking for the comet in the constellation Lynx, located between Jupiter and the Big Dipper. The best viewing times are just before dawn or right after dusk, especially in mid-October when the comet should reach its peak brightness.
Don’t miss this rare opportunity to witness a celestial traveler that visits Earth only once every 1,350 years!
