Jupiter Takes A Meteor Hit

Tue Sep 11, 2012 9:06 pm

Jupiter took a meteor hit last night. If you consider the size of the flash and Earths relative size to Jupiter... Well it's a good thing it hit Jupiter and not Earth...

Extremely cool, thanks for sharing.

On a seperate note I read a long time ago that if Jupiter was 8 times larger, it would then have the prerequisite heat/mass to become a star. Been forever so not sure if that's valid or not.

I wonder what size of meteor would cause such a flash - pretty large, I presume...

Also what does the flash mean - is there ground to the gas giant? Or the fact that the meteor would have been super hot and combusted with gases in the atmosphere?
It's all about the destination AND the journey.

The flash does not mean an impact with something solid. As the astroid went deeper into the Jupiter atmoshere, it would have come apart very violently and exploded due to the rapidly increasing atmosheric pressure. My guess is the flash you see actualy happened several hundred miles inside the atmoshere. This would have been a medum to large sized astroid, but there is no telling what it was made of or how solid it was.

That was the theory several years ago. But now almost no one believes that anymore. With the discovery of some 1500 other planets outside our own solar system it is now believed the gas giant planets cannot become a star based on size alone. Some of the newly discovered planets are several times the size of Jupiter, and the largest one is some 25 X bigger.

We should not completely rule out the infinitesimal probability of an alien ship CFIT.

We all should be thankfull for having Jupiter in our solar system. With it's gravitational pull it attracts meteors and comets that otherwise might head towards us. If Shoemaker-Levy 9 had hit Earth instead of Jupiter it would have been game over for us.

That sounds about right.

IIRC the current working theory is that the 'surface' is actually metallic hydrogen, since the pressure down there would be, well, astronomical.

Haha that would be funny.. they mastered the technology to get them to Jupiter from lightyears away, but haven't yet eliminated CFIT accidents. Wonder what their NTSB would be like..

Would that be in liquid or solid phase?

thanks.

We are still waiting for their 'NTSB' to show up for the Roswell CFIT.

Liquid.

Solid, surrounded by a boundary layer of hydrogen slush.

It just struck me looking at Stitch's link that the gravitational force at the center = 0! Computationally, is there a surface radius at which G is a maximum?

Thanks.

It brought it on itself. That's what happens when you get so massive...

Quoting LMP737 (Reply 6):

Well, there's two sides to that story...
Jupiter is also largely responsible for not allowing planets to form between itself and Mars, due to its gravitational wake which prevented the original nebulae to coalesce in this area. That resulted in the asteroid belt, and when rocks get shaken up from their orbit (sometimes also because of Jupiter's gravity), there's nothing but Mars to take a hit for us.

Gas giants are fascinating.

Please ignore, I am confusing pressure with gravity.
