Wow. I allowed Chrome to know my location for the first time and Street View was in my front door. I thought it was going to use the IP but it's impossible to be that accurate, does it Chrome use my Home on my profile location or something like that?

When you enable location, Chrome will send some pieces of information about your computer to Google Location Services to get your GPS location. Then Chrome sends that GPS location to the site you're visiting. Using information from your profile wouldn't be accurate if you were e.g. at a coffee shop. >The information that Chrome sends to Google Location Services may include: >The Wi-Fi routers closest to you >Cell IDs…

This sounds like I work for Schutzstaffel but just doing paperwork for them

For spotting satellites at night, try my site: https://james.darpinian.com/satellites/ Most of the satellites shown on the Leolabs site are too dim to see without a telescope because they don't reflect enough light. My site calculates brightness and filters down to the ones that you can see with the unaided eye. There are still quite a few! ISS in particular is very bright and can even be seen before sunset.

Thanks for your site! I used it with my kids during COVID lockdown to watch the ISS and other satellites. It’s great

Forced to keep eyes at the floor (for your own good, of course)

I'm impress by the number of objects (well mainly starlink) passing over my head every minute

It's 25x time by default. Things are sped up a lot.

Those long, straight-line convoys of Starlink satellites are fascinating. There's a few of them I could see scattered around the Earth. At what point do they start breaking up into unrelated orbits? Looking forward to using this website to try spotting satellites at night. There's something strangely thrilling about seeing objects in the night sky that were placed there by people.

That’s awesome. We have a few upcoming for the southern hemisphere. Excited to see them!

Thank you for this. While the visualization is useful/interesting, it frustrates me how often similar visuals are used in news stories about space junk. Yes, it's a problem, but using visuals like this without proper explanation misrepresents it terribly.

Yes, and they don't add footnotes. From visualization it looks like crash is inevitable. But yeah, otherwise there would be no visualization. Think about it: they say 19334 objects are tracked. Imagine that many cars or trucks in the world scattered all across. Then extrude that to couple hundreds of kilometers. Would that feel congested to you? 19334 new cars are being manufactured in less than 2,5 hours...

We do love car analogies. I adore them myself. But you did forget one thing. On the surface, a typical car is averaging something like 35 mph. A low earth orbit satellite around 7.8 kilometers per second.

I otherwise totally agree with your point.

I just watched Tiangong space station with my bare eyes. Beautiful. Looking forward to watch 14 starlink satellites tomorrow. Thank you so much for your website.
