A Cool Image Comparing The Sizes Of The KSP Planets

Shows how big Jool is Credit to Smorfty for this image

That's cool.

[Renegrade]

Jool is nearly RSS Earth sized despite being a Kerbin-scale object .. also goes to show that Dres is an angry space potato. It looks like it escaped from the low end of the mun list.

[Tank Buddy]

Huh, I never knew Eeloo was bigger than Dres...

[dryer_lint]

That's pretty cool. Dang, I never knew Duna was so small.

[JebNeedsHelp]

Now I'd love to see how Kerbin's sun compares to the planets.

[Bill Phil]

Not surprising, seeing how Saturn's Radius is ~10x Earth's Radius. And it is freaking HUGE....

Let alone Jupiter.

Guys, this map is not even a little to scale.

Seriously though.

This is awesome.

Smorfty's image

Nice, have seen that before though.

Lonesentry's image

As this is in reply to a scale request, the "not to scale" comment in the top right corner of the image seems somewhat contradictory

Seriously though, unless you're both Smorfty and Lonesentry, it is common courtesy to reference the authors of the images you post... or at least mention it's not your work.

For instance, here is a scaled version of the Kerbolar system including Kerbol by jarrodnb:

And a scaled version of the Kerbolar system with the Earth and Moon as reference by Callum_Evans:

The relative size of Kerbol in respect to the planets in these two images seems off though.

EDIT: jarrodnb had an updated version with the correct Kerbol scale, the image above now displays the updated version.

too much stuff on interwebs

Thank you for posting those images - the first one helps me make sense of it all.

Well, as the Ceres analogue... Its getting off light (or should I say, more massive):

Also, Laythe and Tylo are much much closer to the size of Kerbin than any of the large moons in our solar system are relative ot Earth.

Ganymede, the largest moon in the solar system:

Titan, Saturn's largest moon, only one with an atmosphere and liquid water (and originally thought to be bigger than ganymede, but that was an overestimation due to the thick atmosphere:

[Random Tank]

Interestingly, most planets in KSP are around 10x times smaller than their Real-Life counterparts... apart from the Sun that is!

Our Sun in real life has a radius of a whopping ~696,000km; KSP's Sun is a not to be ashamed of ~261,000km. This means that KSP's Sun is is only ~2.4x smaller than its real life equivalent, making it actually pretty sizable!

The only issue is that the Sun's visual model doesn't scale properly; once you get to lower altitude than Moho, the Sun's model stays the same size, meaning that even when you're 2km above its "surface", it doesn't look any bigger than Jool... Its collision and the kill box are the right size though, just not the visual model. I wish they'd change this, as I like Sun-Diving, and would like to see the sheer scale of it up close

[ImJake]

I like Sun-Diving

Don't we all

To continue on the "real planets" charting - Here's a great one that shows every "round object" in the solar system to scale - anything big enough to form into a ball, instead of a potato.

Ooooh, that's nice! Definitely surprises me how big/small some celestial bodies are as compared to what we usually assume.

[Renegrade]

Well, as the Ceres analogue... Its getting off light (or should I say, more massive):

True - although it's a little high-grav to be a proper Ceres analog (1.13m/s^2 at the surface (2.3x Minmus) vs 0.28 (0.57x Minmus))... (I'm excited about the Dawn mission though, arriving very, very soon)

Also, Laythe and Tylo are much much closer to the size of Kerbin than any of the large moons in our solar system are relative ot Earth.

Also true - especially by my 'surface gravity' reckoning (as densities are kinda all over the place in KSP*, I judge a world's "intended size" by it's surface gravity, and Tylo/Laythe are practically Earth-sized by that system at 0.8g). Maybe I should make a chart myself based on surface gravity instead of actual physical size..

* - also whilst landing, knowing the surface gravity is kinda important

[KerBlammo]

This means that KSP's Sun is is only ~2.4x smaller than its real life equivalent, making it actually pretty sizable!

I'm sure I'm not the first to point out that at that size its the wrong spectral type. It would be a much dimmer Red Dwarf.

[Random Tank]

Oh yeah, no doubt; it's said that it's even too small to be a Brown Dwarf... I meant purely from a scale point of view, supposing that most other celestials in KSP are about 10x smaller

[CG_Kerbin]

I use this image alot when I made two of my videos becuase I wanted to know which planets could fit in each other and also when they went round kerbin I was doing it smallest to largest

[Dr. Kerbal]

Thanks. Now i can expect how how to land on Ike.

[purpleivan]

One  thing I like about that pic is comparing the size of the smaller moon to the crater bay, on the equator of Kerbin. The smallest 4 fit inside it comfortably and Ike's not much bigger than it.

Yes in fact Minmus fits very well... a possible origin story?
