Meanwhile, gases froze into giant balls that would build the outer gas giants.

The gravity of the outer gas giants quickly drew these elements in, bloating them into their current forms: solid cores of rock and ice covered with gas.

While we have four inner rocky planets and four outer gas giants, many other systems have «hot Jupiters» very close to their star.

The star Kepler 36 has two planets: an inner rocky world slightly larger than Earth, and an outer gas giant about the size of Neptune.

Six planets orbit a star roughly the size of the sun, and like our solar system, the outer planets are gas giants while the inner ones seem to be denser.

This is because pockets of gas rich in heavy elements would be created if a comet in the outer regions of a solar system got vaporised by a dying star in its red giant phase or by the expanding planetary nebula that follows it (arxiv.org/abs/1001.4513).

Indeed, our moon would seem more at home in the outer solar system, among the massive satellites that orbit the gas giants.

The two gas giant planets did a gravitational dance with the sun and each other that sent them hurling in then back out to the outer solar system.

Those time spans coincide with known stellar behavior: once a year, for example, a red giant pulsates in brightness, an event astronomers think is linked to an episodic shedding of gas; likewise, every 5,000 years the helium in an outer layer of the star ignites and burns up in a flash, and the star undergoes a brief burst of expansion.

Robotic spacecraft, such as Pioneer 10 and 11 and the Voyager probes, gave us our first close - ups of the gas giant planets in the outer solar system.

This planetary formation theory presumes that gas giants always occur in a solar system's outer orbits.

I'm still holding out for the news that reads: «Second Earth Found» -[this exoplanet] will have all the right ingredients: orbit its star inside the habitable zone, spectroscopic analysis will reveal a nitrogen - rich atmosphere, evidence of water, roughly the same mass as our planet and it will belong in a system with a couple of gas giants shepherding the outer system.

A Neptune - like gas giant may orbit Vega in an outer orbit, «pushed out» after its formation by a larger Jupiter - like planet in an inner orbit (more).

a. Gases dissipate rapidly in the vacuum of outer space, especially the lightest two gases — hydrogen and helium, which comprise most of the mass of the giant plaGases dissipate rapidly in the vacuum of outer space, especially the lightest two gases — hydrogen and helium, which comprise most of the mass of the giant plagases — hydrogen and helium, which comprise most of the mass of the giant planets.

On June 16, 2008, a team of astronomers announced at the 2008 Extra Solar Super-Earths Workshop in France their discovery of one «super-Earth» type planet in a tight orbit around this star with two other gas giant planets in outer orbits (ESO press release and Bouchy et al, 2009).

Planetary candidate «c» appears to be a gas giant with 72 percent of Jupiter's mass (shown here with Europa) in an outer orbit.

Moreover, as a giant star swells, the temperature of its outer gas envelope falls, and so less light is produced there.

Presumably, the strong stellar wind emitted by giant stars eventually blows the titanium oxide out of the star's outer regions (along with hydrogen and helium gases and dust made of elements and molecules like carbon) into interstellar space, until vigorous convection brings out more titanium and oxygen that are created from nuclear processes deeper in the star.

As a second - ascent giant brightens, the star's outer gas layers become unstable, and it may begin to «valve» its outgoing radiative energy by pulsating which also changes its brightness.

Given the low abundance of elements heavier than hydrogen, moreover, it is possible that the star is more likely to have gas giants in cold outer orbits.

Pluto has long been a misfit in the prevailing theories of the solar system's origin: it is thousands of times less massive than the four gas - giant outer planets, and its orbit is very different from the well - separated, nearly circular and co-planar orbits of the eight other major planets.

These planets are called gas giants, because they are mostly made of gas and do not have a solid outer crust.
