How Big Is That Comet We Just Landed On? Here Are Some Sci-Fi Comparisons

Comet 67PYesterday humanity made history by successfully landing a spacecraft on a comet for the first time ever, thus bringing the scenario from Armageddon one step closer to becoming a reality. The European Space Agency’s Rosetta mission, which has been going on for the better part of a decade now, approached Comet 67P and unleashed its Philae lander, which touched down and started transmitting information back to Earth. It’s a momentous occasion for the species, and this ball of rock and ice hurtling through space is now the seventh heavenly body we’ve touched. We know this is a big form flying around out there, but it all sounds so abstract and can be hard to visualize. Fortunately for us, some folks out there have taken it upon themselves to put Comet 67P into a context we, as science fiction fans, can wrap our heads around.

Over at Nerdist, they took dimensions of the comet and compared it to the specs of various elements of popular science fiction, which, again, gives those of us familiar with such things a new way to think about this that makes sense to our pop culture addled brains. For instance, if you ask yourself, well, how does this compare to a Galaxy Class Starship from Star Trek? This handy image shows you just how it compares. It’s also much bigger than Deep Space 9, but is roughly equivalent to both the Borg Cube and a Federation Space Dock. So now you can picture just how big this thing is.

Comet 67PIf Star Wars is more your thing, this picture puts 67P up next to the second Death Star, and there’s really no comparison. Once fully functional, the Empire could blast that out of the sky without so much as a second thought.

Comet 67PThough it is much smaller than the asteroid where Han, Leia, Luke, Chewie, and the droids hide the Falcon in A New Hope

Comet 67P…it’s still way bigger than many of our favorite starships from sci-fi, like Serenity…

Comet 67P…and even Galactica, which I always think of as being rather huge.

Comet 67PHere’s one that compares the comet to more terrestrial objects, things you could actually have seen in real life, you know, like Godzilla.

It’s not even just the nerds out there that are getting in on the action here. The Washington Post, about as mainstream a media outlet as you can get, came up with this handy little image. It gives you the shape, the size, the dimensions, and then, just for the hell of it, puts it up against an Imperial Star Destroyer.

    No comparison to shuttles Freedom and Independence? Seems like no brainer lol

      That’s a great point, they spend a lot of time with made up things, but what about ones that really exist.

      • Kevin Gilbertson says:

        The ones that really exist are millimeters long on the scales given here, I mean the space shuttles are approximately 60m (184 feet) long, That puts it at slightly smaller than the Serenity which is barely visible on the fourth picture.

        • Brent McKnight says:

          That is an excellent point as well. And they do have the picture with the likes of the Empire State Building, which is tiny in comparison, a space shuttle would just be a speck.

    Shouldn’t we focus on what’s going on with poverty, starvation, and the endless wars first before we go gallivanting all over space?

    That’s no moon
