Suns GEEK ALERT

[on:]

All those episodes that have more than one sun.   A Pharoh to Remember,   My Three Suns


Those planets would be uninhabitable. It would be so hot you would burn to a crisp   
 
Just a thought

Dont mess...with the Geek

How can you know that?

Ever been on a Planet which has more than one Sun.

(btw, -> Tatooine - hot, but you could live there  )

[Reply #2 on:]

wtf

[Reply #3 on:]

The heat's not really the issue - the issue is to do with the physics of orbiting three suns.  Think about how it would have to orbit. The suns must all be the same mass, because otherwise the more massive suns would pull the less massive ones out of orbit and they would merge with the more massive one.  Taking that into account, think of the type of orbit the planet would have to take in order to orbit all three. So unless two of the suns are orbiting the other one, the planet system probably would not work concentrically.

My tuppence!

There's no reason the suns would have to be the same size. Astrophysicists are aware of multiple systems with two or more suns of different sizes. Alpha centauri consists of Centauri A and B, both stars like our own, orbiting each other, both orbited by Proxima Centauri, a much smaller star.
AFAIK, astronomers have proposed ways a planet could orbit two or more suns, but since nobody has developed a law of gravitation for more than two bodies...

[Reply #5 on:]

Maybe the two suns evolve around the bigger one, and the planet revolves around the medium sun revolving around bigger sun.  It would be cool enough to survive most of the time, but once a year when the planet orbiting the medium sun came near the big sun then everyone would burn to a crisp...

whose to say they cant have suns that orbit the planet?  What if the planet was denser/heavier than the suns, theoretically the suns could orbit the planet and as long as they were different distances away, it could work

[Reply #7 on:]

when i saw the title for this topic i thought it was about the british newpapaer the sun, and how it hates nerds.

it is possible to have twin sun system, or even 3 or 4 suns orbiting abound it other. Im not absolutily positive about this though, as all my general knowledge of physics is gained from reading all the red dwarf books.

I don't think that's possible.  Given the mass that would have to be involved, the planet would itself develop into a star.

[Reply #9 on:]

There are mutliple sun systems in existence, but I'm not sure if they have orbiting planets. It is possible though, and I'm sure the universe is large enough to have at least one example of this, however unlikely.

And on the heat thing, the planet's wouldn't be too hot to live on because the heat would depend on the distance from the stars, type and size of the stars and the density of the ozone layer surrounding the planet.

[Reply #10 on:]

we cant forget boiling the atmosphere.

[Reply #11 on:]

ok here is my reason....

If there was more than one sun in the solar system. The planets would be like mercury or venus, because it would be so hot in the system.

Mecury and venus are so hot because they are so close to the sun, there hotter.

If there were more than one sun in the system. I theroize (spelling) the entire system unless the planet was extrodinaryly far away....would be very hot.


I will do some reserach. Before I go to my movie

[Reply #12 on:]

Reserach did something

mabey the planets have binary stars
and the drawer people couldn't draw it.

I'm over thinking

Use the button!

Multiple suns doesn't mean hot planets - the suns could be further away than ours, or they could be 'cooler' than our sun.
It would lead to more temperature variations than a one-sun planet, though.

And besides the problem of a planet larget than a sun turning into one, there's also the fact that the gravity would be... (calculates) at least 1,000,000 times earth gravity.

[Reply #15 on:]

I think that the planet would be unlivable because of the fluctuating gravity. That's what happens with Io, a moon of Jupiter I think (correct me if I'm wrong). The fluctuating gravity caused by multiple other moons and the gravitational field of the planet itself means that the surface of Io is under constant change.  It's essentially one huge spherical volcano.

[Reply #16 on:]

Look at how many moons Jupiter has, like 17 or something?  Why couldn't it have little tiny suns instead of moons?

[Reply #17 on:]

Sil: The gravitational pull on the sun on earth is minimal - far less than the moon has (after all, the moon causes tides, the sun doesn't). Assuming a planet with multiple suns orbited at a similar distance to earth, gravitational peturbations wouldn't be a problem.

JDHannan: There's a certain minimum mass a sun must have to sustain fusion. IIRC Jupiter is right on the borderline between planet sized and brown-dwarf sized (a brown-dwarf is a sun that hasn't quite ignited), and anything smaller than jupiter can't be a sun.

like when its day its summer?...when its night its winter

[Reply #19 on:]

Geek> May i also remind you that the people living there were made of water? kind of hard to "burn to a crisp then"

And also there are many factors involved. The suns maybe cooler then our sun is they maybe further away from the planet thus not making it to hot and also livable.

[Reply #20 on:]

they could evaporate.

Whats keeping the water people from evaporating.

note...on all of the planets with multiple suns, we see very little vegitation, (the only plants we see is inside)

Well, I was thinking seasonal - like when it's closest to the suns it's hotter, and when its most distant, it's colder.
Bear in mind, though, that you wouldn't have normal day-night cycles (depending on how the system was structured)...

[Reply #22 on:]

Alright, one, we don't know if they were actually water, they were liquid but not necessarily H2O am I right? Course I am. Two, the suns could be much cooler, in fact the giant sun is red, and those red stars are actually relatively cool (marvellous what you can learn by reading sci-fi)
third, it's possible they are obiting the planet, we don't know what's out there in the universe, they could be constantly burning moons for all we know, forth, it's not necessary the planet is orbiting all three, they may be closely orbiting the red one while the other two are hotter but further away.

*pumps hips* yeah boys and girls you feel that? Also, shut up geek.

[Reply #23 on:]

You're probably right, Arachnid - I don't claim to know anything about physics, so most of what I say is probably bullshit.  And what's with all the being harsh to Geek?
