I will not have it finished for a few days still, but would like to see if there is some interest.
Will take ctp, Planet fluxes(800ctp), Terraforming Device(720ctp), or Quasi-Spacial Expander(1000ctp)
No ku or em.
Will consider other artifacts.

I am willing to reserve the planet it desired.

definately interested at around 3.5k ctp

17x in what? owned by you? and what is meant by "not have it finished for a few days still"?

I am a Kronyn. I can increase the research out put of a planet.
It will be 17x in research, because gas/plasma planet only has research.

if you are needing trading material, selling planets you build up is a great way.
this was given to me, hope it helps

To work out a price:
 
Step One: Pick the resource of your planet
 
1xMega rich = 200-250 CTP
2xMega rich = 250-350 CTP
3xMega rich = 350-500 CTP
4xMega rich = 500-650 CTP
5xMega rich = 650-800 CTP
6xMega rich = 800-950 CTP
7xMega rich = 950-1100 CTP
8xMega rich = 1100-1300 CTP
9xMega rich = 1300-1600 CTP
10xMega rich = 1600-1900 CTP
11xMega rich = 1900-2200 CTP
12xMega rich = 2200-2500 CTP
13xMega rich = 2500-2900 CTP
14xMega rich = 2800-3200 CTP
15xMega rich = 3200-3600 CTP
 
Step Two: Multiply you planet price by the numbers given here;
 
Eg: 15xMega rich Very Massive = (3200CTPx1.25 - 3600CTPx1.25) = 4000 CTP - 4500 CTP
 
If planet is Average x Resource price by 0.70
If planet is Large x Resource price by 0.85
If planet is Very Large x Resource by 1.00
If planet is Massive X Resource price by 1.10
If planet is Very Massive X Resource price by 1.25
If planet is Colossal X Resource price by 1.40
If planet is Mega Colossal X Resource price by 1.60
 
Step Three: Add your passive ability's to the total
 
Eg: 15xMega rich Very Massive with 500 Attk + 400 Def = (4000+180 CTP - 4500+310 CTP) = 4180CTP - 4810 CTP
 
Attack bonus: 5x20 - 5x30 = 100CTP - 150CTP
Defense bonus: 4x20 - 4x40 = 80CTP - 160CTP
= 180CTP - 310 CTP
 
1x100 Attack = 20-30 CTP
1x100 Defense = 20-40 CTP
1x100 Cloak = 20-30 CTP
 
Hope this helps!
 
These are the current prices, and how I am working out what planet's are worth! All prices are subject to change.

This price guide is good but TO EXPENSIVE for all planets

ALOT of planets, sell for cheaper like 15x mining, very large - i've brought some at 2,000ctp a planet,

looking at this, this is for artifact planets, gas and mining will be alot less.

thanks
I have seen this before

by this the planet is estimated at 6k ctp

There was another one last week or the week before that sold for 5k or so CTP. That sounds like a reasonable price for both parties involved.
