Infobox

I've attempted to make an infobox template for planets, Template:Planetbox, to bring it closer in line to the stock parts here and planets on wikipedia. Any advice would be welcome. — Preceding unsigned comment added by Craigmt (talk • contribs)

• So far, so good. I think you have more columns than you originally anticipated, though, so many of the cellss are floating around. -- N3X15 (talk) 19:22, 24 September 2012 (UTC)
• Yeah, the length of the template is breaking some formatting stuff on articles it's transcluded in. It looks good, but I'd personally trim it down to mass/diameter/etc. and leave orbital information in the article proper. --  Trinexx  ►  19:34, 24 September 2012 (UTC)

So, leave orbital characteristics in the article itself and keep physical characteristics in the box? — Preceding unsigned comment added by Craigmt (talk • contribs)

• That's my personal recommendation, at least. I imagine other people have their own opinions on the matter. --  Trinexx  ►  20:40, 24 September 2012 (UTC)

Links

All the links used in the references are broken. Just an FYI. -- N3X15 (talk) 09:55, 1 October 2012 (UTC)

'Kermunist'

Should this term really be used? Thecoshman (talk) 18:28, 7 October 2012 (UTC)

There are no factions in the game, so it would be better to not have that in there, as it'd cause confusion. We do need a Manual of Style to cover stuff like this. -- N3X15 (talk) 20:30, 7 October 2012 (UTC)

Atmosphere

I edited the atmosphere section to make clear the units of d_k & p_k after working through gamedata. Still unsure what units p_k are in FlightGlobals.getStaticPressure() values are in atm, with 1 atm = 101325 Pa to get an absolute static pressure value needed for ideal gas law

-Kellven

Should it be mentioned that because Kerbin has plant and animal life, that therefore the atmosphere is similair to our own? That would be a bit quick on the draw given that even our atmosphere is extremly hostile to some earthbound organisms. --Azivegu (talk) 08:33, 13 December 2012 (UTC)

Orbital information

it mentions in the infobox that Kerbin has a o ecc and 0 inc orbit.. i don't think thats correct, can someone plug the correct figures in?

Maltesh's rip of the 0.18.2 orbital parameters has those, and a quick check in map view shows Kerbin's altitude and speed not changing anywhere in the orbit, so it should still be correct. UmbralRaptor (talk) 06:48, 1 February 2013 (CST)

I'm not sure it's the best place for this information, but I linked to the planetary data spreadsheet and text files at Celestials#Notes. — Elembis (talk) 10:54, 1 February 2013 (CST)

Well, that will teach me to open my big mouth before checking my facts. I guess the inclination of the other bodies is measured relative to Kerbin. Oops. Kahlzun (talk) 21:14, 8 February 2013 (CST)

Map

Does anyone now what projection the map is in? a link to the relevant page would be nice, i am refering to the one in the Topography section

What map do you mean? — xZise [talk] 02:37, 22 April 2013 (CDT)

I would guess Equirectangular projection as the one degree in both axes in File:Kerbin heightmap.jpg have always the same length. — xZise [talk] 08:15, 18 May 2013 (CDT)

Orbits

I crunched the numbers using a few different methods and I keep getting a discrepancy between my numbers and the listed figures (I calculate a GEO orbital velocity of ≈1109 m/s, a difference of exactly 100 m/s). Can someone confirm this? Otherwise, tell me why I'm wrong. ;) -- Eurousalas (talk) 14:51, 22 April 2013 (EST)

I can confirm both. This confirm your value while this confirm the value of this page. What formula do you use?

$v={\sqrt {\frac {G\cdot m}{\sqrt[{3}]{\frac {p^{2}\cdot G\cdot m}{4\cdot \pi ^{2}}}}}}$

m = orbited body mass, p = orbital period

— xZise [talk] 14:54, 22 April 2013 (CDT)

Thanks to a friend, I know what your mistake is: The GSO altitude is given relative to the planet's surface not gravity center. Now {{OrbitVelocity}} and wolfram alpha need this value to be from the gravity center. So you need to add 600 km to your altitude and then you get the correct value. — xZise [talk] 15:03, 22 April 2013 (CDT)

Ack, I knew it would be an obvious mistake. Thanks for pointing that out, it would have bugged me for a long time. -- Eurousalas (talk) 17:46, 27 April 2013 (EST)

Map

I'd like to note that both true-colour maps are outdated. Saik0 on the KSP forums has made maps which are not outdated and in Full-HD and uploaded them on http://www.kerbalmaps.com/ . The website includes anomaly locations (optional), elevation maps, slope maps and true colour maps for all bodies in the Kerbol system except for Kerbol and Jool. He also put those maps online for download at https://mega.co.nz/#F!8EAnSL5Z!OAyLBQqrQtlmfL0GT8fcQg!EBYyXRxA . I have not uploaded any of these images myself yet, because e.g. the Duna true-colour map is something like 77.5 MB where 2 MB are allowed and I'm unable to compress them. I came here to ask if someone would be interested in compressing these for the community. Oh also, here have his KSP forums thread: http://forum.kerbalspaceprogram.com/showthread.php/25148-Web-maps-of-all-bodies-(0-4-ALL-bodies-mapped!)?p=307335#post307335 MmPMSFmM (talk) 07:42, 2 July 2013 (CDT)

I'm wondering where the Kerbin map is on your download link? Here are my suggestions to compress them:

• Use a compression format like png/jpg
• Reduce the resolution of the image (may not be needed when compressing with jpg)

— xZise [talk] 08:36, 2 July 2013 (CDT)

I just found out why you can't find the Kerbin files on that MEGA site: on the forums the author says that "it is his first map and only has half the resolution of the others" and that he will upload it once he redoes it. Also I'm having problems with that MEGA site and Firefox, can't download the files, because of some message about accepting another message that doesn't appear for me... --dgelessus ^{(talk · contribs)} 09:23, 2 July 2013 (CDT)

I'm able to download the images. I tested Gilly but when I tried to edit gilly_0.19.1_0.02197265625_-180_90_180_-90_16384x8192.elevation.tif (which I guess is the most important type of map?) I can't open or edit it because: convert: Sorry, can not handle images with 32-bit samples.. Maybe I find a way to fix this and I'll upload some files. — xZise [talk] 19:10, 2 July 2013 (CDT)

Making Geosynchronous Orbit More Exact?

I see the formula for the calculation of geosynchronous orbit, but that only gives the orbit within the tens of metres. Through some calculations I've found that the closest I can get is 2868750.72505 metres. Would we be willing to change it?

Considering that it is practically impossible to get the orbit that exact, I don't think it's necessary. 2868.75km is more than close enough.--Ruedii (talk) 19:13, 23 July 2013 (CDT)

Elevation update

With topology changes in 0.21, the highest known elevation will have likely changed. My current efforts with a 52 million sample file from ISA Mapsat show a new highest elevation of 6765.1 at location +61.6,+46.34, but I want to confirm that with a landing before updating the page and also wasn't sure if I had missed any higher points.--Khyron (talk) 02:12, 28 July 2013 (EDT)

Surface gravity

I suggest adding a percentage value to the surface gravity inside the info boxes of the planets. This percentage value, denotes a comparison to Kerbin. So the 9,81m/s² acceleration of is 100%, and the value of other planet is an according value. Another way of denoting this value, would be to set Kerbin's s as 1 and then use that to compare the gravitational acceleration of other planet. Polemon (talk) 14:39, 11 September 2013 (CDT)

You are talking about using “g-force”: 1 g = 9.81 m/s². This is in theory possible, but I'm not quite sure if this is really helpful. The template is already enormous and Kerbol System/Table for example show them for you. — xZise [talk] 15:06, 11 September 2013 (CDT)

Why useful: When designing crafts that are supposed to land on other celestial bodies, I like to test them on Kerbin beforehand. Doing this kind of calculation is "OK-ish", but I don't see why it shouldn't be in the infobox as well. Polemon (talk) 15:12, 13 September 2013 (CDT)

btw, I fixed your comment - looks like you accidentally overwrote xZise's message. --dgelessus ^{(talk · contribs)} 15:21, 13 September 2013 (CDT)

Okay as there is already enough space, I added it. — xZise [talk] 05:04, 15 September 2013 (CDT)
