Have you come up with the climate and weather of this planet?
Featured By Owner Sep 10, 2018  Professional Digital Artist
In a basic way: it is a hothouse world, with an equatorial region largely too hot to inhabit unprotected. No ice on the poles, and powerful hurricanes.

What is the axial tilt of Chriirah? And how long is a Chriirah Day/Year?
Featured By Owner Edited Apr 26, 2018  Student Digital Artist
I have my own personal theory for how long a Chriirah year and day could be. Seeing as Chriirah is about the the same radius as Venus, or about 0.95% of Earth's radius, the time it would take for Chriirah to make a full rotation would be approximately 0.95% of Earths, or about 22 hours and 48 minutes.

Then I tried figuring out what Chriirah's solar year could be. While we do not currently know how far away Chriirah is from its star, Alex Ries said it's orbiting a G-type star like Earth's, meaning it's distance from its star must be pretty similar. Considering the drastic effects of climate change on Chriirah, it could also be assumed the planet is slightly closer to its star than Earth, but still in the habitable zone. I used 336 earth days to represent 1 Chriirah Year.

Now, this is where it gets complicated. I tried figuring out how many Chriirah days are in 1 Chriirah year. 1 Earth day equals 1.05 Chriirah days, so 336 earth days would equal 352.8 chrirah days. Obviously this is not a whole number, but Earth shares a similar problem having 365.25 days. The Birrin could have a leap year every five years. A normal year would be 352 chriirah days, while a leap year would be 356 chriirah days.

Interestingly, 352 is divisible by 11, giving us 32. A Chriirah year could consist of 11 months, 32 days each. The leap year could have a twelth month consisting of only 4 days, known as a intercalary month (en.wikipedia.org/wiki/Intercal…)

Since each month is equal in length, they can be divided equally, too. 1 month of 32 days can be divided in 4 weeks consisting of eight days each.

Here are the conversion formulas:
1 Earth day = 1.05 Chriirah days
1 Chriirah day= 0.95 Earth day

Also I was writing this, I realized the Birrin have 3 fingers on each hand. Humans use a Base 10 numeral system because at a young age you learn to count using your fingers. The Birrin could use a Base 6 system, counting 1,2,3,4,5 and then 6 being '10.' This video does a much better video at explaining what I am talking about: www.youtube.com/watch?v=U6xJfP…

Using the Base 6 system, a Chriirah decade would be 6 chriirah years, a century 36 chriirah years, a millennium 216 chriirah years, and a myriaannum 1296 chriirah years.

What map projection is this?  The grid suggests a plate carrée, but I don’t quite get that impression by comparing it with the globe at right, so I don’t want to jump to conclusions.
Featured By Owner Mar 10, 2018  Professional Digital Artist
I believe I used the same projection Nasa Blue Marble does
Featured By Owner Mar 22, 2018
Ah.  Then it is a plate carrée.
Featured By Owner Feb 7, 2018  Hobbyist General Artist
Beautiful world. Birrin have a lot of potential for what I know of them even though they seem to be a disturbed race like humans. XDDDDD Ah! Do you know how many planets the Chriirah system has?
Featured By Owner Feb 10, 2018  Professional Digital Artist
Will do a solar system design for the book
Featured By Owner Feb 28, 2018  Hobbyist General Artist
Okay, I think it will be interesting.
Featured By Owner Nov 20, 2017
Are there gas giants in this solar system?
Featured By Owner Jan 18, 2018  Professional Digital Artist
Yep for sure
Featured By Owner Jan 19, 2018
how many?
Featured By Owner Feb 7, 2018  Professional Digital Artist
Havent designed the system yet. Will be fun to do so though.

Thanks!

Holy wow!

Are these cities now considered canon in the Birrin Universe?
Featured By Owner May 10, 2018  Professional Digital Artist
No cities on the map

Hurricanes must be common on chriirah
Featured By Owner Nov 13, 2017  Professional Digital Artist
Common, and very powerful.

Also I've wanted to do a world building project for a while now and i was wonder if you could give me any tips?
Featured By Owner Nov 13, 2017  Professional Digital Artist
Try to consider the complexity of our one planet when you design yours; there is no one 'human culture', etc
Featured By Owner Edited Sep 28, 2017
What type of main-sequence star is Chriirah orbiting? How many planets deep into the solar system is it? (third, fifth, etc)
Featured By Owner Oct 8, 2017  Professional Digital Artist
Still have to design the full solar system, but the sun is similar, though slightly hotter and older, than ours
Featured By Owner Oct 14, 2017
okay
Featured By Owner Oct 10, 2017
Ah, I see. Still a G-type then, I take it (just older)?

This is such a cool map. I love the detail and concept. I hope you don't get this a lot, but could you tell me the program you used to make this map? I want to make a map for my aliens' world
Featured By Owner Oct 8, 2017  Professional Digital Artist
I used photoshop and actually hand drew the borders of the continents, then photo-bashed earth images from Nasa Blue Marble to make most of the terrain
Featured By Owner Oct 8, 2017  Student General Artist
Featured By Owner Oct 8, 2017  Professional Digital Artist
Most welcome
Featured By Owner Jul 16, 2017
So kiln region is basically everything between tropics?
Featured By Owner Jul 23, 2017  Professional Digital Artist
Yep, a baking world
Featured By Owner Jul 23, 2017
If so, poles I assume must be subtropical in climate now?
Featured By Owner Oct 8, 2017  Professional Digital Artist
Poles are temperate edging into subtropical yeah, though with much more limited light
Featured By Owner Jun 23, 2017
How many nations exist politically? I assume the dominant ones come from the north and south, and good ol'fashioned mad maxery happening in the kiln regions, probably under political and economic dominance from polar nations.
Featured By Owner Jul 23, 2017  Professional Digital Artist
Havent decided yet but there are a large range of small tribe/city state type cultures that formed after the fall
Featured By Owner Oct 13, 2017
Is there anything to read on the Fall?
Featured By Owner Oct 27, 2017  Professional Digital Artist
Only what is contained on this DA site, basically.
Featured By Owner May 10, 2017
Wow and is male a moon of this planet?
Featured By Owner May 17, 2017  Professional Digital Artist
Male is a moon of the main moon
Featured By Owner May 17, 2017
o___O how does that even work?
Featured By Owner May 20, 2017  Professional Digital Artist
The main moon orbits the planet, and the smaller moon orbits the main moon. The orbit is unstable
Featured By Owner Nov 9, 2017
so a moon or object can be ejected or something?
Featured By Owner Nov 15, 2017  Professional Digital Artist
Yep, over centuries/millenia its orbit will bring it crashing down or cast it out somewhere
Featured By Owner May 20, 2017
Now that makes sense like the idea still! keep at it!
