"Jupiter the Largest and Oldest Planet in our Solar System".

According to new research scientists founded that the largest planet in our solar system and also oldest is "Jupiter: An international team of scientists from the Lawrence Livermore National Laboratory (LLNL) thinks it's finally solved the mystery. The Gas or Ice gaint formed with four mullion years after formation of sun.With the help of age of Jupiter is key for understanding how the solar system is evolved towards its present day architecture.

Jupiter formed relatively early, until now its formation has never been Dated."We do not have any samples from Jupiter, in contrast to other bodies like the Earth, Mars, the moon and asteroids," said Thomas Kruijer, lead author of the paper and a researcher at LLNL, in a press release. ".




Thomas Kruijer, from Lawrence Livermore National Laboratory (LLNL) from 'US' said that, They do not have any samples from jupiter (in contrast to other bodies like the Earth, Mars, the Moon and Asteroids). "In our study, we use isotope signatures of meteorites (which are derived from asteroids) to infer Jupiter's age."

By looking Tungsten and molybdenum isotopes of iron and growth by analyzing the ages of certain iron meteorites the researchers dated Jupiter's formation (Isotopes are versions of elements with different numbers of neutrons in their atomic nuclei.)


This work indicated that the meteorites came from two distinct "reservoirs" that were spatially separate for 3 million to 4 million years, beginning about 1 million years after the solar system formed, the researchers said.


"The most plausible mechanism for this efficient separation is the formation of Jupiter , opening a gap in the disc and preventing the exchange of material between the two reservoirs," said by kurijer.
Jupiter's is the oldest planet of the solar system and its core would have to be about 20 times more massive than Earth to keep the two reservoirs from mixing, Kruijer and his team calculated. So, the results suggest the nascent gas giant was already that big within the first 1 million years of solar system history, the researchers said.



Jupiter is currently about 318 times more massive than Earth.
