Is the word "plummet" really appropriate here? They're talking about falling at a rate of 0.001mph, which is much faster than expected but hardly a "plummet."

Yeah, plummet is like straight down till it hits something. Given it's root is in "plumbum" it's not surprising and yes, this is used incorrectly. Not being prescriptive, but this usage is pretty misleading.

Just finished reading the article with the exact same question in mind. Plummet gets the clicks though, so to the website, it is appropriate. It could also be argued it's a sense of perspective. Something that falls at the rate of 2km per year suddenly in a matter of months starts to fall at a rate of 20km per year could seem like plummeting when you're the one tasked with keeping it alive or the person that paid for…

This. To space folks, that is plummeting. It's enough of a difference, and a surprise, to have a significant effect on business models.

Too many HN threads just seem to be people arguing about the appropriateness of the title. The article addresses a significant and interesting issue that's going to have major negative effects on business models, as well as some positive effect on space junk. I think they did a decent job, at least for an article intended for the general public, and I'm glad I read it. And yes, the word "plummet" is an exaggeration. But that isn't a big deal.

I am thinking about a commercial data product to address the situational awareness need here. It feels daunting though, because customers would be the likes of SpaceX and other intimidating entities. If anyone has thoughts, or is interested, please send me an email. (Contact info in profile!) Thanks.

Wow, so you are telling me satellites are falling to earth and burning up in the atmosphere? No? Oh.. ok.

It's a significant difference that has a real impact on the satellites. But we also don't say that airplanes plummet when landing or elevators when going down.

To me at least, plummet signals it's a matter of seconds or, perhaps from great altitude, minutes until it hits the bottom. So to me, and that's knowing a thing or two about space, this title is just clickbait and not a good description of the phenomenon observed even for a techy public like HN.

Well now that we've determined that plummet maybe isn't the right word to use, shall we discuss the fact that satellites are unexpectedly falling from the sky in yet another climate change that we had not predicted?
