Anyone know? Any guesses or theories?

Well there seems to be no definate answer in the G1 cartoon Cybertron seemed to be somewhere between earth moon size and earth size. I also read somewhere although for the life of me I can't remember where Cybertron is suppose to be the same size as Saturn. So your guess is as good as mine.

Yeah, I was going to say Saturn too. And I can't even remember where I heard that...

Cybertron would have to be a large planet, the Transformers themselves are a fair size.

Yeah, it'd have to be pretty big. I don't remember what episode it was, but in G1 Cybertron actually got moved to near Earth! I dunno how they managed that, but the carnage that followed demonstrated that Cybertron's mass was great enough to have a drastic effect on Earth's rotation. Unless Cybertron is made of very dense material, big mass means big size so I'd say bigger than Earth. A little bit bigger at least, but we're talking about one big honkin' planet here.

According to the first issue of the Marvel comic, Cybertron was supposed to be a Saturn-sized world.

Now to me, that makes sense given the fact that the average Transformer is pretty big when compared to human standards. I just don't see how a planet of millions(more? less?) of giant robots living on a planet the size of ours wouldn't be crowded.

Saturn sized, eh? That's pretty cool. Makes sense too. So, Primus can play basketball with the earth if he felt like it.

I do n ot feel that a planet the size of saturn and made of rock and metal would be really feasable.

For instance, jupiter's size and mass is almost enough for it to be on the permanant edge of solar ignition. If it had more mass it could ignight and become a second sun.

Metal and rock is more dense than gas so a planet the size of saturn made of such materials would have an incredibly huge gravity at least.

I would think Cybertron would be about 2 times the size of earth or maybe just hte size of earth. They may be giant robots but there were giant animals on this planet as well.

Cybertron is a multi layered planet with cities above and below the ground they do not have great oceans or seas tying up huge areas of the planet. They may have deep chasms but they can easily build down them, span them with roads and build cities off teh walls.

So earth could fit transformers if you think of the whole planet minus the water.

Yes, but don't forget that our solar systems size is dictated by the size of our sun. The tf had a double star system. Not sure how that would work out for gaseous/rocky planets but he increased mass is definately there.

A planet's gravity is related to its mass. In several Transformers episodes, humans go to Cybertron. They are able to move about with apparently no difficulty, meaning Cybertron's gravity just HAS to be nearly equal to Earth's. The only way the planet could be big AND have Earth-like gravity would be if Cybertron were hollow or built in layers as Sunstar says. If there's anything we should be considering, it's atmospheric composition!

I think Sunstar has the right idea, and bare in mind that there may not be as many TFs living on Cybertron as there are humans on Earth, so the amount of space may still be sufficient on an earth sized world.

I agree that making it roughly the size of earth leads to the least headaches. Mostly regarding gravity, especially in context of technological functionality.

I think, according to the sources we've seen, that there is a lot of hollow space within Cybertron, which would account for a reduced mass. However, you also need to bear in mind that the surface gravity is not just related to the mass of the planet, but its radius too. If Cybertron is roughly Saturn-sized, then for the surface gravity to match with that of Earth, its mass must be proportionately greater to compensate for the greater distance between the surface and the core.
As for the atmosphere, the DW MTMTE series actually stated that Cybertron has a "light oxygen-based atmosphere", which apparently is "suitable for the cooling needs of mechanical-based life". Exactly what that means, I'm not sure.

I think that Saturn though is the only size that is actually given in any series.

None of the more recent shows have actually mentioned the size of Cybertron itself, although the Galaxy Force series seemed to make it about the size of the Earth, The moons of Cybertron seemed to be about the same scale as our moon to Earth.

Of course this is all relative, as the moons themselves could be larger than Earth if Cybertron was Saturn sized.

lets also take into consideration that if Cybertron, barring the primus Theory, was an actual Planet at one time with rocks, lakes, treses, ect.. over the course of developing that into the Large Machine structure it is in the current timelines would mean the considerable shrinking of the planet as it becomes Metallic...


I think a thin atmosphere is derrived from what remaining plant life and Algea factories that are pumping the gas into the stratosphere abouve Cybertron, to give them a somewhat breathable atmosphere..

When i was a kid, i always believed that in some way humanity was involved in creating the Transformers and that the last of them died out, that Cybertron was a futurte Earth that had been used to go backwardss in time to revitilize the hunman populace, and that over the millenia after our sun imploded the Human scientist created the Transformers, to do their work, slowly retreating closer to the core of the planet of heat, ect...

the experiments went awry and they eneded up billiions of years in the past and seperated into factions and began warring... it was a good idea as a kid trying to figure out where the Transformers came from.. and that was before I knew about the Quintessons...

I heard that 3 times the size of the Earth.

Cool idea, man!
Kinda reminds me of the old Starriors comic from the 80's.
Human creators would be a great way of explaining why they'd have human faces, i.e. emulating their gods.

As for Cybertron itself, yes I remember well that the first page of issue #1 said that it was a Saturn sized world. One thing that seems to be forgotten though is that the planet was shaken from its orbit due to the war and sent adrift through space. A machine covered planet the size of Saturn would have a better chance at surviving such a fate, but I can still see why the planet was scaled down. A human going to such a place would be crushed flat by the gravity before suffocating to death.

I would assume the same size as Unicron since he and Primus (Cybertron's robot mode) are supposed to be brothers. That doesn't really answer the question being asked, but it's the nearest to an opinion I have to answer with.

It's just too interesting a question to ignore.

As big as Jupiter I hope.

Its slightly smaller than Earth's moon. It was transported to Earth in the Gen 1 episode The Ultimate Doom. It was just big enough to affect Earth's gravity and weather systems. But if you watch the episodes, you can see it in scale to the moon and it is smaller. Also, it was small enough for Unicron to stand on it and look foolish. FYI.

Yeah, in the movie. Hadn't thought about that.

I hope that one like the guy who make all the last years the bust, statues from the Transformers decides also make a 1/25 scale Cybertron Planet, that would be much simpler for my fancomic...

All this speculations means there should be a Cybertron Spotlight

Ok first lets go by some logic
Super Earth planets (rocky planets the size of jupiter) are known to exist outside our solar system(they must have insane plate tectonics) But I think that cybertron is the size of the mars or smaller

Here is my reasoning cybertron is mainly made of metallic elements right so it's density is going to be much higher than a silicate based rocky planet. Also lets take the basic physics of giant robots. They probably can't function well in environments higher than two G's (maybe only Decepticons because they all seem to have antigravity drives.)

Also if the whole "crust and mantle" of cybertron are inhabitable then millions of robots can exist there without being as crowded as a Tokyo train.
