Why isn't comet 67P round? Why do they call it "sound" what they're now finding? Why "67P?"

See three questions.

Lots of pictures and stories. (It’s quite extraordinary for a paper “tabloid journalism.”)

The singing comet.

Why is it named 67P? Personally, I think they should have come with a name name, even if it upset the standard nomenclature (which I am guessing is the derivation of “67P”), given the importance of the mission and need for public interest.

It’s got a name name already, but that’s hardly any better: 67P/Churyumov–Gerasimenko.

Its full name is 67P/Churyumov–Gerasimenko, which is named after its discovers , Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko

Looks like 67P is for the 67th Periodic (orbit less than 200 years) Comet


The comet isn’t spherical because it isn’t massive enough for its gravity of overcome other opposing forces.

It wasn’t the original target comet. Originally they were aiming for 46P/Wirtanen but the window closed on them due to a launch failure. Comet naming follows a format to allow for the relatively quick naming of bodies discovered since we are discovering so many. Wiki says:

Finally they call it sound the same why they tell you space has a flavour. It’s good press and it kind of describes what they found - unexpected variations in the magnetic field strength.

Hell of a link! Thanks.

Thanks, BOOM!! Welome to SD, BOOM!! Look forward to seeing your name BOOM! around, BOOM!!

Just a slight little aside, I see that Klim Churyumov and Svetlana Gerasimenko are both still alive (if Wikipedia is up to date) - were either of them present during the initial rendezvous or the landing? I’d imagine it would be extremely exciting for them, the first to discover and catch a glimpse of this object, to actually see it up close and personal.

They were present during the live streaming of the landing, although in different locations.

Here’s a pic of Churyumov hugging the General Director of the ESA at the ESA control center.

I haven’t seen any pics of Gerasimenko at the event.

What’s that orange thing on his wrist?

Wild guess - it’s a wristband of solidarity with the aims of the Ukrainian Orange Revolution (He’s Ukrainian)

Didn’t that guy write a poem about The German Guns one time?

No, he invented the slap shot in hockey.

They should call it the Lion Comet. Its resemblance to a lion in this picture is uncanny. I’m not the only one to recognize this; someone on reddit noticed the same thing.
