Comet C/2022 E3 (ZTF)

A comet reaching the inner solar system intact is typically a rare astronomical event. As a comet approaches the sun, it sometimes breaks up, and so it is common to refer to a comet as having survived the sun. Once the comet survives and comes close to the Earth, it may be possible for it to be viewed with small telescopes or binoculars, or even with the unaided eye.

It’s safe to say C/2022 E3 (ZTF) was a rarity, not only because it survived, but it is said to be on a path with a return period of about 50,000 years. The photo above captured the comet as it passed through the constellation of Taurus approaching Mars on 10 February, 2023 (captured with Askar FMA180 + AA 26c + iOptron Skyguider Pro.

  1. An exceptional image, Drexel, capturing the faint cometary coma and tail, along with the red hue of Mars.

    If you trust Wikipedia, it states that the inbound trajectory is about 50,000 years but the predicted outbound trajectory is millions of years and potential ejection.

  2. I love the color! I was hoping it would brighten up a bit more and show a bit more of a tail, but you never know about those things until they happen. Not bad to be part of a one in a 50,000 year occurrence! Thank you as always for sharing! 👍🔭💯
