The formation of gas giants has to takeplace within the lifetime of the gaseous protoplanetary disksurrounding a young star in which the planet is forming. So,solid planets have to grow large—and rapidly—ifthey are to become gas giants. In the Solar System at least,the giant planets orbit quite far from the sun..
Simply so, how are gas planets made?
The core accretion model. Artist's conception of oursolar system's solar nebula, the cloud of gas and dust fromwhich the planets formed. But farther away, the solar windshad less impact on lighter elements, allowing them to coalesce intogas giants. In this way, asteroids, comets, planets,and moons were created.
Likewise, how Jupiter is formed? Formation. Jupiter took shape when therest of the solar system formed about 4.5 billion years ago,when gravity pulled swirling gas and dust in to become this gasgiant. About 4 billion years ago, Jupiter settled into itscurrent position in the outer solar system, where it is the fifthplanet from the Sun.
Keeping this in consideration, what are gas giants made of?
A gas giant is a large planet composedmostly of gases, such as hydrogen and helium, with arelatively small rocky core. The gas giants of our solarsystem are Jupiter, Saturn, Uranus and Neptune.
Are gas giants solid?
Unlike rocky planets, which have a clearlydefined difference between atmosphere and surface, gasgiants do not have a well-defined surface; their atmospheressimply become gradually denser toward the core, perhaps with liquidor liquid-like states in between. One cannot "land on" suchplanets in the traditional sense.

Is Pluto a gas planet?
Lying 30 to 50 times as far from the sun as Earth,Pluto's composition bears a greater resemblance to the rockyterrestrial planets than the gas giants that are itsneighbors.

Composed predominantly of hydrogen and helium, themassive Jupiter is much like a tiny star. But despite thefact that it is the largest planet in the solar system, thegas giant just doesn't have the mass needed to pushit into stellar status. When scientists call Jupiter agas giant, they aren't exaggerating.What type of planet is Earth?

How does a planet form?
The various planets are thought to have formedfrom the solar nebula, the disc-shaped cloud of gas and dust leftover from the Sun's formation. The currently accepted method bywhich the planets formed is accretion, in which theplanets began as dust grains in orbit around the centralprotostar.What is Jupiter's atmosphere?

How was Pluto named?
Pluto was finally discovered in 1930 by ClydeTombaugh at the Lowell Observatory, based on predictions by Lowelland other astronomers.
