question about how to live on another planet

I don't understand. If you are talking about Earth rotating from the current north pole to the south pole, then any of the current equatorial regions (including Singapore) can be a new polar region. It all depends.

well.. the thing is.. also that only happen at 2 regions and the other 2 the planet will have long exposure to sunlight and darkness... (donno what i am saying.. still trying to picture it)

i take that people have to migrate a lot then? or just maybe live underground then.

Yes, it is possible for a region to be a "new polar region" with low temperatures for most part/whole of the year , but not for "a day in the equator will be alternating between tropical conditions to extreme polar freeze". Refer to above.

It depends on whether you want to live in different conditions throughout the year. Yes, the temperature would change, but what I'm saying is--most people wouldn't migrate, the temp changes aren't drastic enough to warrant a migration. This is beacuse our temperature is mainly controlled by earth's atmosphere, not amnt of solar radiation.

hmm..earth is not completely like venus, we do have an atmosphere, but not like venus. our atmosphere does not contain mostly greenhouse gasses like carbon dioxide. thus the unlit side will prolly be much colder than the lighted side, maybe 20-30 degrees difference.

..ahh.. i guess i forgot about the atmosphereic part.
i am thinking more like mercury with no atmosphere and therefore you get very hot on one side and freezing cold on the other.

..... i just thought during the 2 times of the year where half of the planet will be fully exposed to sun / darkness. the planet (and its people) might not be able to ''live'' through rather than the other times when its just a ''normal'' rotation. (did i just repeat myself)

anyways....

thx~

I repeat, yes, it is possible, but temp. changes of more drastic than that will not occur within a "day" on the equator (define day?). More drastic temp changes will require a long exposure to total darkness/brightness for a long period of time. Refer above.

Two reason why earth will never have that drastic a temp change no matter what the tilt of axis. Firstly the orbital period of mercury is around 88 days, but its rotational period is arnd 60 days. Although Mercury is not tidally locked to the Sun, its rotational period is tidally coupled to its orbital period. Mercury rotates one and a half times during each orbit. Because of this 3:2 resonance, a day on Mercury (sun rise to sun rise) is 176 Earth days long. This means that sides of mercury are exposed/kept away from the sun for long periods of time, therefore drastic temp changes occur. Second reason that Mercury has these changes is because it has little atm, therefore unable to trap/circulate heat energy on the surface of the planet.

But of course if you saying earth's axis is tilted like uranus, it would have a great temp difference between the lit and unlit side, which are both exposed/unexposed to the sun of long times. One side would be freezing cold while the other basking in the heat. But not that bad lar(like venus or mercury). Because we have just the right amnt of CO2 in the atm to trap and circulate heat energy to a habitable temp.

mint greentea,mercury HAS an atmosphere.Its just a thin layer of captured solar wind

that thin layer of solar wind wont do much of a difference i think.

would they all converge to the ''equator'' part region? or probably the ''tropical'' parts?

I think the area where they live will probably depend on where they first appear and whether they want to migrate or not. I mean, people of the past think that earth is flat, so accord to that thinking, the climate should be the same everywhere, so they wont know about earth being warmer at one spot and colder at the other.

Their way of lifestyles will probably be similar to earth, except at they have 3 months of dawn, 3 months of noon, 3 months of dusk and 3 months of night. so its 6 months of work (agriculture probably) and 6 months of stargazing (yeah!)

finally i remembered a method to find the *almost* exact anomalies when earth is tilted like neptune : Celestia. www.shatters.net/celestia download that program and modify the .ssc file and get the tilt info from neptune and paste over earth.Happy nights
