It's tidally locked to earth. Earth isn't tidally locked to it. Happens slowly due to gravity and differential mass. Relatively stable satellites end up tidally locked given the time. Pretty sure lack of water/liquids/atmosphere hastens the process.
Mercury orbits the sun every 88 earth days. It spins on its axis every 59 earth days, relative to an outside observer (sidereal day.) That makes the solar day (from sunrise to sunrise) 179 earth days long.
No. I rounded off the numbers. A Mercury day is exactly 2 Mercury years. Which is why it’s “in resonance”. That means that gravity will speed up or slow down the rotation to keep the ratio stable over time.
Pretty sure they have 100 percent mortality rate as most animals do. There are some species of jellyfish that technically are immortal (capable of immortality anyway) - they revert back to a polyp stage and start life over again without dying. But every other animal species, like us humans, does have to bow down to the grim reaper at some point.
“Caterpillar” is not a species. It’s a stage of some animals’ life cycle. It means 99% of catepillars die before they become butterflies or moths or whatever
If there are other immortal animal species, what are they? My comment about jellyfish being immortal was from the article in national Geographic. What are the animals you are thinking of?
The hydra. There’s a species of worm (pretty sure it’s a flatworm, could be a round one though). Technically, lobsters are too. They also aren’t cos growing their news shells is incredibly taxing and that’s how the old ones usually succumb, but yeah, genetically, they do the whole telomere regeneration shit. Their DNA is like 17yo when they die at age 130. So, yeah.
Hydra, eh? According to the web, hydra are "virtually immortal" in a lab environment. On the other hand, though I've heard lobsters could be immortal, the web (which obviously is the only true source of info, wink wink) says it's a myth, eventually the lobster will die "from exhaustion during a moult." However I know they can live a long long time, many animals can easily out live humans.
Oh ffs. I swear to god we don’t deserve the internet. I literally pointed out that lobsters do die. The reason we can consider em immortal is cos they clean up their telomere damage. You colossal idiot. You’re trying to trip me up and “expose” me, but you can’t even get the fundamentals right…
Even if we planted a trillion trees it would only have a tiny affect on climate change. Same with killing large amounts of people. The only way we combat climate change effectively is getting off fossil fuels.
It’s the heaviest part of the moon which face us. And even when it will reach it’s farthest and definitive orbit ( the moon slowly move away from us), it will still the same face toward us.
I was skeptical thank you for the confirmation. Especially because the time it takes to lock depends on the relative size of the bodies. Our moon being exceptionally big relatively to our planet, if it has locked, then relatively smaller moons should have locked long before.
Btw, the locking is not perfect, there’s a little oscillation of the moon called libration, so we can actually see about 59% of it over the years.
Pedantically speaking, yes. At least some small moons do freely rotate. But they are all very small and very far from their parent planet. If you were on the surface, you wouldn’t see details.
Mars has two small moons close to it, but neither rotate relative to the surface. They’re also really small and zip about super fast so they’re cool for other reasons.
