The planets - jupiter a belt of asteroids (fragments of rock and iron) between mars and jupiter separate the four inner planets from the five outer planets jupiter, the largest planet in our solar system, was named for the most important roman god because of its size about 1,300 earths would fit into it viewed through a. Astronomers finally know how old jupiter is the gas giant's core had already grown to be 20 times more massive than earth just 1 million years after the sun formed, a new study suggests jupiter is the oldest planet of the solar system, and its solid core formed well before the solar nebula gas dissipated,.
Gas giants like jupiter have to grow fast newborn stars are embedded in a disk of gas and dust that goes on to form planets but the ignition of the star releases energy that drives away much of the gas within a relatively short time thus, producing something like jupiter involved a race to gather material. Venus and jupiter, the two brightest planets in the solar system apart from the moon and the sun, stayed low on the horizon and were visible in the eastern sky the planets could be seen by the naked eye, although binoculars offered a clearer view and maybe even of jupiter's moons read more. You mean if jupiter never existed well in that case, earth may not even be formed if it weren't for jupiter our solar system is pretty weird over the past few decades scientists have discovered and confirmed over 1000 exoplanets which are planet. 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 idea that there were originally five gas giants – in addition to jupiter, saturn, uranus, and neptune.
Jupiter is the fifth planet from the sun and the largest in the solar system it is a giant planet with a mass one-thousandth that of the sun, but two and a. Jupiter is the fifth planet from our sun and the largest planet in the solar system. Jupiter is the fifth planet from the sun, and the largest planet in the solar system jupiter is almost big enough to be a star with a diameter of 142,984 km, it is so large that all of the other planets in the solar system could fit inside of it jupiter is a gas planet made of 90% hydrogen and 10% helium the outermost layer is.
Because jupiter has most of the mass of what the sun left over, we can think of the solar system as a double star with very unequal partners the little guy ( jupiter) is 1/1000 the mass of the big one (sun) and doesn't have enough mass to produce the pressure necessary for ignition at its center it does have pretty much the. An analysis of meteorites shows that jupiter divided the rocks of the asteroid belt into two families within the first million years of the solar system. Jupiter is the biggest, most massive — and according to the latest research — oldest planet in our solar system the news comes from the lawrence livermore national laboratory where american researchers, with the help of german colleagues at the university of münsterin, found jupiter must have.

Astrophysicists at the university of toronto have found that a close encounter with jupiter about four billion years ago may have resulted in another planet's ejection from the solar system altogether the existence of a fifth giant gas planet at the time of the solar system's formation — in addition to jupiter. Jupiter was probably the first planet in the solar system to form, new research suggests its existence may have influenced how the planets evolved into the order we see today amy a simon, nasa, european space agency jupiter was an early bloomer a close look at the ages of rock and metal.
Jupiter formed in a geologic blink its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported monday in the proceedings of the national academy of sciences within another 2 million or 3 million years, that core grew to 50 times the mass of earth scientists. Along with the sun, the gravitational influence of jupiter has helped shape the solar system the orbits of most of the system's planets lie closer to jupiter's orbital plane than the sun's equatorial plane (mercury is the only planet that is closer to the sun's equator in orbital tilt),. 4 days ago jupiter: jupiter, the most massive planet in the solar system and the fifth in distance from the sun.
