habitable zone
habitable zone
many astronomy programs have the opcion to put the habitable zone of a star because celestia does not print it.
Good idea.
what do the different colors mean?
FYI: Each H.Z. changes with its own star.

Temperature
Blue -100 <T <0 C
Green 0 <T <100 C
Red 100 <T <200 C
Now you will wonder why the earth is far from the green zone, the earth has about 5 degrees of radiation, the atmosphere gives it 2, the ocean gives it 4, the mass 1 among others also add up to 12 and the greenhouse effect
gives you 21. giving us a nice temperature of 33 degrees
Added after 2 hours 4 minutes:
Above the habitable zone without greenhouse effect, below the habitable zone with greenhouse effect Above the earth with 5 C now 33 C
Added after 48 minutes 41 seconds:
Here proxima it is

Look at this picture given by Nasa.
What do you conclude ?

It is not the same to say that it is in the green zone if knowing why it is in the green zone, is that there are other factors that affect the temperature

Go on everybody... the truth is not far.

Three planets the same destiny, only one winner.
Added after 2 hours 18 minutes:
The red means the area where it must have a negative greenhouse effect, that is, the prenet has little mass or little atmosphere or low C02 concentrations for the water to be on its surface, the blue area where it must have a positive greenhouse effect such as high activity volcanic, a lot of mass etc ...

False !
what scientific facts are your zones based on?
Give us your sources !
Here is an another picture from Nasa.
Where is Venus ?

That is bad!, the habitable zone is moving away from its star as its temperature increases, here is a gift with 33 stars I have with spectral type but it made me angry, enjoy it.

Can you read a 'simple' diagram ?
first stage; the abscissa (X) represents the percentage of starlight received (200% to 25%).
second stage : the ordinate (Y) represents the temperature (and therefore the spectral type) of the star.
Is it so difficult to understand ?
Where is Venus ?

Actually, Venus is in the diagram, but its outside any type of the habitable zone, recieving almost twice as much starlight as Earth, so its right on the edge.

But again, Venus is outside the red area in the diagram...

Yes Gurren, and in the twice diagrams.Gurren Lagann wrote:But again, Venus is outside the red area in the diagram...
It reminds me a chinese proverb: "when the scientist points to the moon, the fool looks at the finger !"
