How large is Spherus Magna?

so wait would it be as big or bigger then Jupiter?

Mata Nui’s height is about the same of Earth’s diameter. However, if Mata Nui was supposed to be mostly submerged in water then Aqua Magna would have to be far larger than Earth. And Aqua Magna is a moon that orbits and even larger planet. (If anyone could get and estimation of how Bara Magna is compared its moons, it would be helpful)

So in other words, very, very large. Probably not gas giant sized but far larger than the Earth.

Also, if we could get an estimation of Spherus Magna’s diameter then we should be able to get an estimation of its gravity too. I am curious what those results would be like.

late reply so not exactly the size of Jupiter but a heck of a lot bigger then Earth?

So if its larger than earth, and if we assume that after its second formation it got a liquid iron core, does the planet have a much bigger gravitational pull? How heavy are the residence there if we compare then on earth? How did Bara Magna stay the shape it was, for the amount of planet mass it lost, it should have destroyed each resident on the surface.

We know nothing about the core, and nothing suggests that it is liquid iron.

The inhabitants of Bara Magna, and in fact, the entire BIONICLE universe were never really weighed in the books, so we won’t know unless Farshtey just pulls random numbers out his a**.

Planets are not perfectly spherical at all, they are in fact more like obloids, with a bulge around the equator. That being said, their formation is a result of gravitational pull and centrifugal force. You see, during a planet’s formation, it’s spinning around like a disc, and it continues to spin because of the lack of friction in space, and as it forms it creates a centrifugal bulge around the middle.

So, Bara Magna would still retain its shape after the loss of parts of it’s surface because the planet is done forming. It’s not liquid, its solid, and it’s extremely hard for things, even gravity, to reform hundreds of thousands, even millions of tons of rock to retain an oblong shape. Also, look at asteroids, they have strange shapes and aren’t oblong in any way a planet is. Many have huge craters in them, like how Bara Magna had two from the missing mass.

Also, it would have been impossible for Bara Magna to go back to normal because it would have needed the moons back. You cannot simply create more mass because there are empty holes on your planet.

This is why the inhabitants of Bara Magna are so few in number, and why they are so (relatively) condensed on the surface. Many of the inhabitants likely did die due to volcanic activity, earthquakes and the initial explosion. Those who survived, rebuilt over hundreds of thousands of years.

What happened to the ones after the second forming, we do see some of them surviving but how much of them on the surface would actually survive the formation of Spherus Magna. If the first killed a large portion of them, what did this one do?

Dude, the moons were put back by Mata Nui. They didn’t come down at a fast velocity, or else it would be the equivalent of two huge asteroids hitting the surface. Bota Magna crushed Makuta, and Aqua Magna was also put back into place. GB technology is far far greater than anything we can imagine, they had this planned out. For the most part.

Wait, didnt the thing tha hit Giant Makuta Robots head just a part of Bota Magna. Beacuse if it was the whole thing, than it was really small.

Our own moon is only the size of Eurasia. That, added to the fact that the two robots were incredibly, incredibly massive, makes that a fairly normal sized moon I think.

Its just visually they are very differently portrayed in the short Mata-Nui clips and the comics.

That’s an unfortunate eventuality of telling the same story through different mediums. That’s part of why BIONICLE is so confusing to most people.

Which is why I posted on the forums on another topic that Bionicle really needs a consistent Expanded Universe, writers following what others initial made so that the story is intertwined nicely (a la Star Wars in my examples). IF not than we have this problem I stated.

back on topic, would the planet be the about size of Saturn or what?

@Sharnak Mata nui was on his back, you must remember.

@TheJMPofArcadia Probably something a bit smaller, but yeah, massive. The robots still would have gone far out of the atmosphere.

We were always on topic, just expanding more about the question.

For what i understand maybe its as big as Jupiter.

everyone’s saying more or less bigger then Saturn though. But then again the GSR is about the size of Earth’s diameter, so IDK

There are no solid planets that are the size of Jupiter (get your facts straight!). Gas giants are the largest a planet can get and if it gets larger it becomes a red dwarf star because it gets hot enough to make nuclear fusion.
Planets can have a larger atmospheric level that can even be the size of Jupiter (example: TrES-4) but the mass is a lot smaller than Jupiters.

So you have: Dwarf Planets (solid planets)
Terrestrial Plates (solid planets) like Earth, Bota Magna, Aqua Magna, Bara Magna…
Neptune like planets (solid gas planets)
Gas Giants (gas planets) like Jupiter and Saturn.
Red Dwarf Stars- created from larger Gas Giants, no longer considered planets but Type M stars.

Nonsense! The Stranger from Marvel comics came from Giganta (or something like that), a planet that dwarfed galaxies.
