Astronomers theorize that Jupiter may have kicked a planet out of the Solar System - Polidicks

[URL="http://www.sciencealert.com/our-solar-system-used-to-have-another-gas-giant-planet-but-jupiter-likely-kicked-it-out"]http://www.sciencealert.com/our-solar-system-used-to-have-another-gas-giant-planet-but-jupiter-likely-kicked-it-out[/URL] [QUOTE]Researchers from Canada have used computer models to show that our Solar System could have had an extra gas giant planet in the mix around 4 billion years ago – until Jupiter booted it out, that is. ... The mystery lost planet in question is believed to have had the mass of an ice giant, which means that it was heavier than Saturn and Jupiter, and in the same class as Neptune and Uranus. So how exactly does a lighter planet suddenly kick an ice giant clear out of the Solar System? Planetary ejections generally happen as a result of a close planetary encounter - but not necessary a collision - which causes one of the objects to accelerate so rapidly that it's able to break free from the massive gravitational pull of the Sun and go slingshotting out into the galaxy, becoming what's known as a rogue planet. In this case, the ejection could be the result of Jupiter moving closer to the Sun from further out in the Solar System, affecting the orbit of other planets on its way.[/QUOTE]

god jupiter way to be an asshole

Call it Cronus

Oh god, this is going to feed the Nibiru/Planet X conspiracists even more. "IT'S GOING TO RETURN!!" ...how? It's probably tens of light-years away and likely a drifting metallic/whatever core with whatever gas it hasn't yet lost to the interstellar medium. However, this could be quite interesting for helping us understand the evolution of solar systems. Or maybe it's just a nifty historical footnote. I don't know.

Jupiter is our solar system's bouncer

[QUOTE=Ninja Gnome;49062718]god jupiter way to be an asshole[/QUOTE] Jupiter also prevented the formation of planets between itself and Mars, the result of which is the asteroid belt. Jupiter is well known for being the biggest asshole in the Solar System.

It's Nibiru!11!

this isn't that Tyche thing again is it? i thought the WISE data disproved that there could have been anything in or near the Oort cloud, unless it happened on a really ridiculous time scale

Isn't Jupiter also responsible from saving our asses from comets/asteroids?

I have a feeling some how its Jupiter's fault that Mars doesn't have animal-like life (or even life at all).

This has actually been speculated for a while as the reason for Uranus' and Neptune's orbits and the lack of content in the kuiper belt and asteroid belt. Many models even speculate that Uranus and Neptune switched orbits and that the original solar system was far more compact, with the outermost gas giant being in a comparable position to modern Saturn, and the primary consensus by these models is that the cause was Jupiter and Saturn entering a 1:2 resonance, making them cause very powerful gravitational wobbling to occur and distort the orbits of the rest.

[QUOTE=Zero-Point;49064051]I personally wonder if there's an abundance of "rogue planets" such as this, and that's what this mysterious dark matter actually is.*[/QUOTE] The amount of rogue planets necessary to account for the mass accounted for as dark matter would mean that we'd see hundreds to thousands of Jupiter-sized planets within a light year of us, which just isn't the case. We already have telescopes capable of detecting the radiation of rogue planets larger than Jupiter and none of them are within 6 light years of us. The mass of dark matter in our galaxy alone is several orders of a magnitude higher than rogue planets could realistically account for. To give an idea, it's believed that there are ten times as much mass within dark matter within the Milky Way than there is normal matter.

There is a theory of a rouge planet hitting the earth and its the reason why we've got cloud formations today as a result because it cracked the surface and lead to a few things like for example the moon. Its a theory, Wonder where that planet is now then.

[QUOTE=Passing;49064315] Its a theory, Wonder where that planet is now then.[/QUOTE] inside the earth's mantle, according to the stuff I have read recently about it. Apparently most of the moon, or at least it's crust, comes straight from Earth as ejects during the collision. Theia would have been obliterated and absorbed into Earth's lava seas after the impact.

Such a scary thought to think that something the size of a planet can just be flying through the galaxy. Imagine if one came this way.

[QUOTE=Mechanical43;49064141]well when you say stuff like that and you have no idea what you're talking about, yeah it's only normal for someone to come and school you so no rogue planets (it's the actual term !) are not dark matter because dark matter doesn't interact with light. meaning that it's pretty much invisible to us. but on the contrary we can see rogue planets, they emit light in the infrared spectrum and that's detectable by telescopes![/QUOTE] Neither of you are entirely right, though between you you have the currently accepted solution. There's two overarching, different categories for dark matter: MACHOs and WIMPs (laugh it up). MACHOs are Massive Astrophysical Compact Halo Objects. These would include things such as planets, neutron stars, and other `dark' objects that are physically difficult to see (though in principle not impossible) which would contribute to the total mass of galaxies. WIMPs are what most people think of when they think of dark matter proper: Weakly Interacting Massive Particles. Invisible shit that we can't [I]directly[/I] see due to a lack of electromagnetic interaction. Both contribute towards the 'unseen' mass of galaxies, though there's no way there's enough MACHOs floating around to make up all of the dark matter, so we expect most of it's WIMPs (there are other theories such as Modified Newtonian Dynamics (MOND), but... we don't talk about those).

[QUOTE=Dr.C;49062822]Jupiter is our solar system's bouncer[/QUOTE] It actually is. Most asteroids/comets that are in wildly elliptical orbits that could cross paths with earth eventually cross paths with Jupiter. Jupiter either literally eats them, shoves them into the sun, or punts them out of the system.

[QUOTE=kidwithsword;49062831]Jupiter also prevented the formation of planets between itself and Mars, the result of which is the asteroid belt. Jupiter is well known for being the biggest asshole in the Solar System.[/QUOTE] But by making the asteroid belt we have a near-endless supply of resources (many of them very valuable) to mine in low-grav.

[QUOTE=Da Big Man;49065813]Not too scary when you realize that space is [i]fucking huge[/i][/QUOTE] Honestly, for many people its really really hard to grasp just how big space is, and i dont blame them, its really hard to put inti some sort of perspective

[QUOTE=Ninja Gnome;49062718]god jupiter way to be an asshole[/QUOTE] well jupiter has probably saved us countless times by taking punches from Kepler belt objects, so you probably shouldn't be putting it down so much [editline]7th November 2015[/editline] like it got pummeled by Shoemaker–Levy 9, if that hit earth it would have destroyed the planet's surface and possibly a big chunk of the planet [t]https://upload.wikimedia.org/wikipedia/commons/d/dd/Chain_of_impact_craters_on_Ganymede.jpg[/t] they suspect this 120 mile chain of craters on Ganymede was from a similar object.
