More Jovian Star questions

Well sbarry66<br />Lets save Europa then. Wasn't it saved already before..hihihi.(use the links for further info)<br /><br />Io always points the same side toward Jupiter during its orbit and so also does Europa and Ganymede. Because Io is at only at more or less 422,000 kilometers (262,000 miles) from Jupiter (and due other moons) Io is subjected to extreme tidal forces causing its surface to bulge up and down by as much as 100 meters (330 feet) and this is ground bulging not water like the tides on Earth. Another factor is due to Europa and Ganymede perturbation on Io's orbitn Io follows an irregularly elliptical shape affecting considerably its distance from Jupiter (that is why more or less 422,000km). In fact Io, Europa and Ganymede are in a constant orbital fight and every time Ganymede goes around Jupiter once, Europa makes two orbits, and Io makes four orbits. Io's orbit also cuts across Jupiters powerful magnetic field and that turns Io into a electric generator. Io can develop 400,000 volts across itself and create an electric current of 3 million amperes. This current is also responsible for the lightning in Jupiter's upper atmosphere since it follows the magnetic field lines of Jupiter. Jupiter rotation takes its magnetic field around and stripps Io off about 1,000 kilograms of its material every second. The material becomes ionized in the magnetic field and forms a doughnut-shaped cloud of radiation called plasma torus then some ions p

All great, except even if you add all Jupiters moons, Saturn Uranus Neptune Earth Mars and all their moons, you STILL don't have enough mass to start fusion and create a star. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

This is why you need a "graviton generator" to artificially increase Jupiter's mass. Any civilization that has mastered this graviton generator will also be able to partake in advanced space travel, as propulsion becomes trivial when you can create a gravity source in front of your ship.<br /><br />Another possibility we've not mentioned is actually siphoning material from the sun itself. Now we're probably putting ourselves more than a couple hundred years in the future to do this, but the sun has all the material you could ever need. An added side benefit is that the sun's fusion slows, making it last longer, and burn slightly cooler. Is this future humanity's global warming answer? That could go into the storyline as well. You save Earth at the same time you create a new world orbiting Jupiter...<br /><br />Of course, the problems of basic unsuitability of most of the Jovian moons has been mentioned. And the timescale for moving so much material from the Sun to Jupiter is going to be in the millions of years unless we can hypothesize some teleporting or wormholing method...

I know MeteorWayne and I mentioned that in the first post. Either you put a Brown Dwarf hitting Jupiter and risk wipping out the entire Jovian system or you disregard the critical mass required and create other conditions and try to be as close as possible to science thereafter. It is a sci fi after all. <img src="/images/icons/wink.gif" />

Thanks to everyone for providing so many wonderful theories regarding this. I'll poach what I can to create a reality that at least attempts to remain true to the laws of physics. I'll keep monitoring this forum for any additional ideas that pop up.<br />

A passing star<br />I do not know the year of the script but in 1.4 million years the red dwarf star Gliese 710 will be passing close to the solar system and affecting the Oort Cloud.

Even a close passing massive body wouldn't necessarily add significant mass (of the right type) to Jupiter.<br /><br />The Sun is still the Great Attractor in the system. EVrything else is just a random target. <div class="Discussion_UserSignature"> <em>"2012.. Year of the Dragon!! Get on the Dragon Wagon!".</em> </div>

Obviously not specially Gliese 710 a red dwarf with a mass of 0.4–0.6 solar masses and passing at 1.1 light years (70,000 AU). <br /><br />The idea is to have Gliese 710 passing so close and dragging the Oort Cloud, Kuiper Belt objects, Pluto or even Saturn, Neptune and Urane into a collision with Jupiter.<img src="/images/icons/wink.gif" /><br /><br />It is for sci fi after all and we are trying to come up with some ideas on how you could jump start Jupiter as star which is by no means an easy task without a cosiderable amount of mass being added.

I'd invent the technology (somewhere in the back-story of your scenario) to produce a wormhole, one end inside the sun, the other at Jupiter’s core, with a duration just long enough to pump the required mass into Jupiter. It'd probably work if you had the technology.<br /><br />What you can't do is pretend that crashing a moon into Jupiter would have any effect whatsoever. Just because it's science fiction, you can't simply ignore physics or you might as well be writing about witches and sorcerers conjuring a spell to make Jupiter ignite, there's no difference. What you <i>can</i> do however is invent technology which has the desired result however utterly improbable that technology might be.<br /><br />The real question is why you would do it, if you had that kind of hardware. Perhaps it was an accident during the first experiments with said technology which inadvertently made the Jovian moons habitable? After the event it was decided to be too risky to use it again, etc?<br /><br />Just thinking out loud. <div class="Discussion_UserSignature"> <p><font size="2" color="#339966"> I wish I could remember<br /> But my selective memory<br /> Won't let me</font><font size="2" color="#99cc00"> </font><font size="3" color="#339966"><font size="2">- </font></font><font size="1" color="#339966">Mark Oliver Everett</font></p><p> </p> </div>

About Stars: Brown Dwarfs<br />Spectral class: T, L, M<br />These can be seen as an intermediate between star and planet. Too small zu start the hydrogen fusion yet some fusion processes take place in their core, especially deuterium to helium and the lithium fusion. Below 13 times the mass of Jupiter an object counts as planet, above 80 times as star (Red Dwarf). In-between are the Brown Dwarfs whose glowing can be measured only by the best instruments.<br /><br />Young Brown Dwarfs gain their energy through the gravitation of the collapsing cloud. When the collapse finishes they cool down and get dimmer, because the fusion processes provide much less energy. After not more than some hundred million years even their fuel for the nuclear fusion is spent.<br />---------------------------
