Jupiter collided with one other planet and ABSORBED it 4.5 billion years in the past
Jupiter utterly absorbed a protoplanet ‘TEN occasions the mass of Earth’ 4.5 billion years in the past after huge head-on collision
- Astronomers from Japan, Switzerland and america used knowledge from NASA’s Juno probe
- Decided {that a} dramatic impression shattered the primordial compact core of Jupiter
- Proto-planets would have collided often within the early days of the photo voltaic system
Jupiter was in a huge head-on collision with a “protoplanet” 4.5 billion years in the past whereas it was nonetheless forming – and the fuel big has utterly absorbed the opposite world.
That is the idea of scientists who’ve studied the historical past of the planet utilizing knowledge from NASA’s Juno house probe.
They imagine that this collision with the planet – roughly the mass of ten Earths – explains its mysterious fuel core.
Jupiter’s innermost layer is made up of stable rock and hydrogen and has lengthy puzzled astronomers.
If their idea is appropriate, it sheds new mild on the tumultuous formation of the photo voltaic system.

Collision: Jupiter was in a huge head-on collision with a “ protoplanet ” 4.5 billion years in the past whereas it was nonetheless forming – and the fuel big has utterly absorbed the opposite world. Scientists imagine this explains its gaseous internal core – which is made up of stable rocks and hydrogen – and has lengthy puzzled astronomers
“ Fashions of such a situation result in a coherent inside construction with a diluted core, persisting over billions of years, ” they are saying of their examine, printed within the journal, Nature.
“A sufficiently big impression between a big planetary embryo and the proto-Jupiter might have shattered its primordial compact nucleus and blended the heavy parts with the internal shell.
“Fashions of such a situation result in an inside construction that’s in keeping with a diluted core, persisting for billions of years.
The crew, gathered throughout Japan, China, Switzerland and america, provides that this situation wouldn’t have been distinctive to Jupiter.

In reality, they add that proto-planets would have often collided within the early days of the photo voltaic system.
“ We recommend that collisions had been frequent within the younger photo voltaic system and {that a} comparable occasion might even have occurred for Saturn, contributing to the structural variations between Jupiter and Saturn. ”
In addition they examined the idea that Jupiter’s fragmented core was attributable to climate erosion or the chance that it nonetheless contained core fuel.
However the examine concluded {that a} colossal collision was almost definitely accountable.
