I will grant that this new comet, C/2019 Q4 (Borisov), does have more of an intriguing orbital path than did C/2017 U1.

But, I am not willing to RUSH to the conclusion that it is interstellar — i.e., it did NOT originate in our own Oort cloud. Still very early days. That it is travelling too fast to be bound to the Sun is interesting.

I was not convinced about A/2017 U1 (ʻOumuamua) being interstellar and now others are joining in. SMILE. I do know some about comets.

All I am saying, for now, is don’t rush to a conclusion. Let’s study this puppy a bit more.

Definitely not going to be GREAT comet. It will be very far from the Sun. Twice as far as the Earth is to the Sun. So, unlikely that it will be very bright or sport a spectacular tail.

Just wanted to keep YOU in the loop. But, stay tuned.


Has a ton of good information about comets.
