fyr02's Fictional System

Post #1by fyr02 » 18.06.2019, 02:55

I have decided to make a fictional system with seven planets: The Kessea System!
Some info about planets:
Tathanus: Rocky planet, 6424km diameter (NOT FINISHED)
Daxitanus: Rocky planet, 13142km diameter (NOT FINISHED)
Destrenus: Rocky planet (Similar to hot Mars or dry Earth), 12624km diameter, 1 moon (NOT FINISHED)
Argolea: Habitable Rocky planet, 12812km diameter, 2 moons (NOT FINISHED)
Fyralivon: Gas Planet, magenta in color, 112063km diameter, 5 moons (FINISHED)
Yuuzoth: Gas Planet, sky blue in color, 96096km diameter, 4 moons, (Finished planets, 1/4 moons finished)
Kostranus: Gas Planet, unknown color, 132451km diameter, 7 moons (NOT FINISHED)

UPDATE JUL 09 2019
Tathanus: FINISHED
Daxitanus: FINISHED
Destrenus: FINISHED
Argolea: FINISHED
Fyralivon: FINISHED
Yuuzoth: FINISHED
Kostranus: Finished planet, 2/7 moons done

Added after 13 minutes 53 seconds:
Fyralivon, fifth planet from Kessea (Spectral Type K2V)

Nice! I can see this as the relaunching of fictional solar systems for Celestia.

Thaddiuq/Yuuzoth III, used to have a subsurface ocean, but resonances with the other moons caused its orbit to circularize, and the ocean dried up. The only remnants are a layer of iron oxide on its surface that colors it red. d=1,894km

Hi,

Nice look !

Where is this sytem ?

If the star has spectral type equal to K2V (less bright than our sun) and the inhabited planet in fourth position, the planets are closer, right ?
What are the distances from the star for each planet ?

jujuapapa,

Here are all of the orbital info for the Kessea System. Moon inclinations are missing but that's the only thing that's not on there.

You should probably update the first post with your progress.

After testing the given data, I found :
1. for the star
kessea_pb.jpg
kessea_pb.jpg (18.99 KiB) Viewed 222 times
=> too small, not enough light !

2. for the inhabited planet
kessea_argolea_pb.jpg
kessea_argolea_pb.jpg (13.85 KiB) Viewed 222 times
=> too cold !

Conclusion : it's NOT possible, just try to be coherent even for a fictional system ! :fie:
@fyr02 => try to update the AppMag (example 12.0) and shorter distance for Argolea (0,46) :wink:

You realize it's a fictional system. FICTIONAL. It's not supposed to be scientifically accurate.

Sorry about that. Those values are generated by Celestia and sometimes those values can by horribly off. I'll try to fix that as soon as possible

Added after 17 minutes 1 second:
EDIT: The correct Radius should be 0.9212 x Sun, or 640703.812 km. The temperature on Argolea should now be a more liveable 238 K.
I've always imagined Argolea to have thicker atmosphere than Earth.
The reason why this happened is that I roughly based Kessea off of HD 40307 and didn't realize HD 40307 was a main-sequence star and not a
K-dwarf.
If you input this it should be fixed

My identity is private. I prefer to be hidden. But there I go again, getting mad at a minor thing. It's just that I get annoyed too easily. Ah, well.

FYI and all other young people because you wrote a little mistake.

The twice stars Kessea (K2V) and HD 40307 (K2.5V) are together K-dwarf on main-sequence stars.
Only their spectral type are lightly different.
To do simply :
ts.jpg

To affinate the temperature we add numeric subdivisions 0 to 9.

to distinguish their life, we add a latin number to see their evolution.

Example : Sun is G2V star.

I know that, the base for Kessea was ROUGHLY HD 40307. I mainly used it because it had a habitable planet that could be used as a guidepost for Argolea.

What I meant by main-sequence star was a K star on the main sequence, instead of a object of class sdK2 or K2IV (example: K2-3)
