Celestia Forums

Hi,
I've created an addon for Celestia, which adds the Kepler-22 star and its probably habitable planet 'b' to Celestia. Recommended to use Celestia 1.6 or newer. All informations about this system is valid. The system is located in the constellation Cygnus. The surface of the b planet is fictionally, because currently we haven't any information about this.
Installation: Just copy the Kepler-22 folder to your 'extras' folder, open Celetia, press ENTER and type 'Kepler-22'.
Kepler-22 on Wikipedia: http://en.wikipedia.org/wiki/Kepler-22
Its planet on wikipedia: http://en.wikipedia.org/wiki/Kepler-22b
Please write a reply how it works.

Hi Shog,

Thanks for your addon. FYI, I have already created an addon for this system earlier in the month which looks to be very similar to yours. (see here:http://shatters.net/forum/viewtopic.php?f=6&t=16696&p=128518#p128518)

People who may have downloaded both versions should be aware that they should install one or the other (but not both at the same time) as they have the same name.

Hi, sorry, i didn't see your addon about this system. I don't know where you got information, but the distance of kepler 22 is 590 ly the magnitude is 11.664 and its radius is 681590km (0.98 RSun). I calculated the position of the star about celestial coordinates from wikipedia. The 'b' planet rotation period is probably bigger of the earth, so I think this is not 16 hours. I got these informations from wikipedia. And you? For the atmosphere I used the Earth's informations, because the planet is similar to Earth. I modified only the height because it is a bigger planet.

No need to apologize, you're just as entitled to make addons, as I am.

I try not to use Wikipedia as it is often wrong (only as a last resort).

I used the following sources:

Hey everyone,

My name is dusky. I heard about celestia from some friend who recommend it to me, so I thought I would join the forums in case I need help understanding the program, help with bugs, and to learn to make the most of celestia program.

In exchange, I will try to point out things that I find about astronomy.

In this case, I think that Kepler-22b's distance might have updated in the orginal paper about its discovery. I suspect this based on the conversation and the fact that http://kepler.nasa.gov/Mission/discoveries/kepler22b/ now shows 190 pc instead of 184 pc (which means its now 619.710889 light years)

Hope that helps

Thanks for your help, I have been updated the informations in the add-on. And welcome to the forum!

Version 1.1 released!

Updates in v1.1:
-some corrected data about Kepler-22 and 'b' planet
