As you know cybertron was significantly smaller than earth in g1 one of the few things i hated about g1 but then again scale in g1 is not consistent
I thinks it should be significantly bigger than earth like other continuities it doesn’t sense that a species with billions as a population not to mention titans live on a cybertron that small not to mention the size difference between humans and an average cybertonian I personally think it was a mistake to make it that small.

 

I think I read somewhere that Cybertron was about as big as earth's moon, if not slightly smaller. Personally, I'd be find with it being like the size of venus or something. Slightly smaller than the earth. Or if it had to be small, as big as mars.

 

I dunno how big it even is, so I have no clue.

 

A thing to remember when considering Cybertron's population is that many versions have layers so maximum sustainable population is based on volume instead of surface area.

That said, my Cybertron is the size of a small gas giant because after hollowing out their own world they strip mined their solar system for more resources.

 

I like the idea of it being the size of Saturn like it allegedly is in the Marvel comics, so I've heard. Lots of space and resources for the big damn robots. But I'd prefer if reason dictated its size.

Chiefly, it should have gravity close to 9.8 meters of acceleration, or 1 g. The following factors would lead me to make my choice.

(!) Cybertronians are typically three or four times the height of a human, so its surface area should be scaled up accordingly

(?) Is this version of Cybertron all metal, or a modified planet originally organic and rocky, terraformed by Quintessons? Earth's total mass is about 60% metal; a Cybertron with a rocky core could be lighter than one with a metal core

(?) If it has no oceans, does it really need to have (proportionally) equal surface area to Earth? Only 29% of Earth's surface is even land in the first place.

(?) Is the interior of the planet fully compressed as tightly as possible? A (artificial) hardened honeycomb mantle structure filled with a low-mass filler material could justify having 1 g on a larger planet with more metal content.

Ultimately, I think the most realistic route would be a planet about the size of Earth or perhaps smaller, with the mass-reducing facets of a honeycomb mantle and a rocky core which used to be the original planet it was made from, with no oceans to take up surface area. As a fan of hard sci-fi who wants to see a take on Transformers that doesn't utterly ignore absolutely every bit of physics it can encounter at every turn, this is the route I'd probably take. A Saturn-sized planet with 1 g would have some pretty wonky gravity at the surface, realistically.

...But goddamnit, "Saturn sized" planet sound so satisfyingly vast for these robits four times our height on average, and I wanna see them do boat warfare on oceans, that I'm okay with Cybertron being the size of a gas giant.




Non-sequitir: imagine living on a planet with no ocean tho. just all land, divided by borders and fault lines. wack.

 

Depends. Do you think it should be the alt mode for a god-bot?

 

I don't think I have much of a preference either way.

 

I like the idea of it being notably smaller. Makes more sense with how few Transformers we usually see, and why for the most part, many of them know each other.

 

Personally I prefer Cybertron to be larger than Earth but not to the level of the original Marvel comics. While Cybertron being the same size as Saturn is impressive, it doesn't make much sense from a gravitational perspective, and this is taking into account the labyrinth of tunnels that make up the interior.

Gravity is calculated by the mass of an object versus how fast it spins and all that metal adds up on top of what the planet's core (being rocky or metallic) so if Cybertron is Saturn size it's gravity would be at least 3 to 4 times that of Earth unless either most of the planet's core and lower mantle is completely hollow or its rotation is next to nothing.

As best I can calculate for Cybertron to be larger than Earth to would have to be in the class of the Super Earth which is 0.8 to 1.2 times the size which this size works for me.

 

I would like a version of Cybertron that changes size depending on factors like the population of the inhabitants, the amount of Energon, etc. Though, the smallest size the planet should go would be only slightly smaller than Earth or slightly larger (depending on the story in question). Would also help with the size changing inconsistencies.

 

Bigger. the robots are bigger so why not their homeworld, it makes perfect sense.

 

Much smaller without question, considering the population and such, that you can see the main cities from space in almost all rendition, and there's only about a dozen or two of them.

For gravity and such, I do regard it as denser due to it's composition being metallic based at a good 50-60 percent, so this compensates for it's smaller size.

For me, it makes a lot more sense that it's actually more of a planetoid that's been mined and converted, with levels going down to it's core.

It also makes a lot more sense as it's free-floating in space, so it does have some maneuvering capacity, and too much mass would make that impossible.

I'd say that it's even smaller than our moon so about 2,500 KM wide, but due to the sub-surface levels, the usable space is quite large.

And for me, Unicron is about the size of a mountain, at around 20 KM in size (planet form) and about 30 KM in robot mode

 

Because the bigger a world the greater its gravity, and the greater the gravity the smaller (or at least less erect) its life forms would be.

Given TFs seem to move exactly the same on Cybertron as on Earth, they really ought to be the same size. It just makes the most sense given there's never a disparity in gravity.

 

Not necessarily. If a world was built in layers, each layer can be constructed so that it would have the same amount of gravity as the planet the layers are built around. There's a video on YouTube that goes over the subject in detail.

 

Science

 

Shooter? Budianski? Or Mantlo described Cybertron as a Saturn sized world. That or it could have been as dense as Saturn. Heck, the Ark was first called Aunty in issue #1 then around 2 and 3, Ark.

 

I mean, for a planet full of giant robots you must expect it to be big.

 

While Cybertronians are bigger than humans, there are also fewer of them. Either way, I think the size of Cybertron could be bigger or smaller. I’m fine with both ways. Making it the same size sucks because that should be Earth and Venus’ special thing only  

 

That’s not exactly correct

The autobots ship was called “The Ark” in the very first issue

Aunty was the name of the ships (“living ?”) Operating computer system…..the Equivalent of Teletraan 1

 

My Cybertron is a Dyson Sphere, so bigger.
