I have not heard of this, https://legalinsurrection.com/2023/01/excitement-builds-as-comet-approaches-earth-for-first-time-in-about-50000-years/

QuoteFormally known as C/2022 E3 (ZTF), the comet orbits the sun every 50,000 years and is set to make its closest approach to our planet on February 1, 2023.

E3 was discovered in March, but scientists recently snapped the first detailed photo revealing its brighter greenish coma and a yellowy dust tail.

While the comet is too dim to see without a telescope, it should be visible to the naked eye when it is roughly 26 million miles away.

Can't wait, hope it is a good one.

Missed It By That Much!!!

Wonder why it is not being talked up more? There's no way of knowing if it was a dud the first time.

I love this stuff! Funny how only just now it's news, and how do they know it was here 55,000 years ago, if they only just spotted it?

Talk about making up numbers.

Determining Comet orbital path  and speed has been going on for a while.  With the capabilities of current telescopes and such, and computing power, it doesn't take a very long observation of the comet to determine the path and period of circulation; depends on the measurements that can be taken from the first time the comet is detected. Here is a good article that describes C/2022 E3 (ZTF).

Actually. My point was, since it's never even been seen before, how can they be certain it's from our own galaxy?
Maybe it was sling shotted into ours from another distant one and now on a new trajectory.

They may be right, but anything is possible.
