90% of starlink satellites are >400km in altitude. They aren't in very low earth orbits where that intuition even might be correct. They're above the space station.
I've definitely seen math done - though I'd have to dig it up again. I think in FAA filings.
The best sources that I can find say that Starlink sats orbit around 550 km above Earth. By all accounts, this distance is well within Low Earth Orbit definitions. However, you used the term "very low earth orbits". I never heard before and needed to research it. It is a neologism from 2017 and does not seem to have a precise definition. Most uses indicate less than 450 km above Earth.
The International Space Station flies around 400 km above Earth.
