On each successive journey to the inner solar system, astronomers on Earth turned their telescopes skyward to watch Halley's approach. Short-period comets need roughly 200 years or less to complete one orbit, long-period comets take more than 200 years, and single-apparition comets are not bound to the sun (opens in new tab), on orbits that take them out of the solar system. That's exciting, because the short-periodicity comets that circle within the solar system are significantly altered from their original form, baked and diminished by many rotations around the sun. Astronomers located K2 in a part of the solar system where sunlight is only 1/225th its brightness as we see from Earth and where temperatures are minus440 degrees Fahrenheit, according to NASA.

And youll need a little patience and a dark-sky site to see it. Even when Shakespeare wrote his play "Julius Caesar" around 1600, just 105 years before Edmond Halley calculated that the comet returns over and over again, he included a now-famous phrase sepaking of comets as heralds: "When beggars die there are no comets seen; The heavens themselves blaze forth the death of princes.".

"When we study these comets, we're trying to look at material has been preserved from the beginning of the solar system. Comet C/2022 E3 (ZTF) has favorable geometry with respect to Earth. Since were a team based all around the world, it just happened that it was my afternoon, while the other folks were asleep. The space object will be more difficult to see for those in the Southern Hemisphere. The gas contains water vapor, carbon monoxide, carbon dioxide and other trace substances, and is eventually swept into the distinctive comet tail. But by the time they do, their power sources will have been dead for centuries. Now, as the comet returns to the outer solar system, we can enjoy what could be the brightest comet of 2023 before it gets too dim to see.
