tfw you don't live at a star that has 3 planets in its habitable zone

Imagine observing another intelligent race just a few million miles away.

tfw you don't live at a planet that has 4 continents in its habitable zone

Imagine observing another intelligent race just a few million metres away.

We basically do, anon.
Venus is an uncanny twin of Earth, and it's not too close to preclude the possibility of liquid water at its blackbody temperature, especially if there were salts and such present (that is, even Earth's oceans wouldn't boil if the temperature reached 100C). It's just rendered a dead world by its stifling atmosphere.

Mars wouldn't be untenable as a life bearing world either, if its atmosphere weren't so depleted. Of course I'm sure you've heard of the idea that at one time in the past Mars may have held life much like Earth's.

Luckier still, beyond these fantastic planets, our Solar System contains many fascinating moons, some of which bear liquid water even today (we can even see the jets of steam being ejected into space from Enceladus).

Judging by our "batting average" in our own back yard (as far as we know, at least), three potentially "habitable" (and that's not really what "habitable zone" means) planets wouldn't even be enough to convince me that there's a good chance of something like life as we know it living there!

(Of course, all that could change as we learn new things about the histories of the other bodies in our own backyard. If we found evidence that Mars once bore life, and the same for Enceladus, Titan, Europa, and such, suddenly we'd be forced to conclude that the majority of "likely" bodies probably have borne life at one time or another.)

Can you imagine the complex organisms that would have evolved to live in such a complicated season system?

>> No.5858758

>>5858749

...The season system would likely be pretty much the same.

Season are caused by angle between the rotational axis and the ecliptic, not the distance to the star. This would not be any different in a binary system.

seems like you are over zealous, more like Imaging observing microbacteria just a few million miles away.

assuming that the planet is in an external orbit of both stars, not an orbit that passes in between the suns. of course, since binary stars are often pretty close together, it might be hard for a planet with the latter orbit to be habitable in temperature.
>>5858749
Or maybe really simple organisms. remember, on this planet it's the prokaryotes that are extremophiles.
