Nailed it!

I’m so happy I wasn’t the only one who saw this.

How perfectly moon fits between earth and the sun is one of the weirdest things about our solar system to me.
BluesF@lemmy.world 1 month ago
Especially because it hasn’t always and it won’t forever. Humanity’s existence just happens to coincide with the period of amazing eclipses.
aeharding@vger.social 1 month ago
Yep this. Call in sick, quit, max out your credit, go halfway around the world, do literally whatever is needed to be done to see a total eclipse if you haven’t been able to experience it yet. It’s unreal.

You kidding?
There is loads of space between the Earth and the Sun to fit the Moon.

No way dude

That’s actually amazing that we have eclipse shots from Mars. Anyone know how it was taken? What instrument?
CitizenKong@lemmy.world 1 month ago
Probably a camera of some sort.
Viking_Hippie@lemmy.world 1 month ago
That would be my guess too. Perhaps aided by a kind of telescope.

NASA’s Perseverance rover on Mars has returned a stunning sequence of images of its moon, Phobos, eclipsing the sun. From Mars’ Jezero Crater, the rover’s SkyCam and MastCam took over 65 images of the event on February 8, one per second, to ensure it captured the short event.

Mars Rover pointing straight up.

I mean she’s not wrong. Isn’t it, astronomically speaking, pretty rare that Earth has a moon that appears exactly the same relative size as its host star?
johannesvanderwhales@lemmy.world 1 month ago
As far as we know it’s extremely rare and a bit of a mystery how it came to be that way. One theory is that it was the result of a collision with another protoplanet in the early formation of the solar system.
JimVanDeventer@lemmy.world 1 month ago
But it isn’t a mystery at all. The moon is moving away from us. For billions of years the moon’s apparent size was larger than the sun. For billions of years later it will appear smaller. It’s simply a lucky coincidence we live in this moment in time, in that regard.

Oh, holy hell, I just uncontrollably giggled at that for so long, my chest hurts. I sent it to my only group of friends, and it looks even better in smaller thumbnail form. Good gracious.

booty@hexbear.net 1 month ago
give it a few hundred million years and ours won’t be able to do a total solar eclipse either :(
threelonmusketeers@sh.itjust.works 1 month ago
Nonesense. We just need to lower the Moon’s orbit every so often to keep it in the sweet spot.

Phobos is this big and still not round?
vithigar@lemmy.ca 1 month ago
Phobos is tiny. It’s just very close compared to our moon. 9500km as compared to our 384000km.
NichtElias@sh.itjust.works 1 month ago
And the sun looks smaller from Mars because it’s further away, making Phobos seem bigger
MonkderVierte@lemmy.ml 1 month ago
Ah, thanks! Also, Phobos is fast!
Live_your_lives@lemmy.world 1 month ago
I believe you are looking for hydrostatic equilibrium. There don’t seem to be good answers for this online, but according to Robert Black on this Quora post:
There isn’t a minimium per se but the generally accepted number for a mass to form into a sphere under its own gravity is 1/10,000th the mass of the Earth or 600 quintillion kg. As for size, it really depends on the composition of the body. The numbers are generally accepted to have a diameter of about 600km for a rocky body.
A quintillion is 1 x 10^18 and Phobos has a mass of 1.0659 x 10^16 kilograms and a diameter of 22 kilometers.
MonkderVierte@lemmy.ml 1 month ago
Yes that, thanks!
Etterra@lemmy.world 1 month ago
I think Mars eclipses might be better. It means they have googly eyes, and googly eyes make everything funnier.
