Not exact matches

«This result is unique because it demonstrates that a giant planet can form so rapidly that the remnant gas and dust from which the young star formed, surrounding the system in a Frisbee - like disk, is still present,» said Lisa Prato of Lowell Observatory, co-leader of the young planet survey and a co-author on the paper.

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.

Planet hunters have found more than 130 extrasolar planets, but nearly all are bloated gas giants like Jupiter.

Many planets outside the solar system are even more massive than Jupiter, and they orbit their Sun - like stars at an Earth - like distance, but these faraway super-Jupiters are effectively giant gas balls that can not support life because they lack solid surfaces.

One suggests that giant planets formed from the gravitational collapse of condensing gas, like the sun did.

This scenario naturally produces a planetary system just like our own: small, rocky planets with thin atmospheres close to the star, a Jupiter - like gas giant just beyond the snowline, and the other giants getting progressively smaller at greater distances because they move more slowly through their orbits and take longer to hoover up material.

If there's gas around and the bodies get large enough, perhaps something on the order of 10 Earth masses or so, then you can start pulling some gas in on top of your rocky core and make something that looks like a gas giant planet, like Jupiter.

«It proves that there is no clear dividing line between rocky worlds like Earth and fluffier planets like water worlds or gas giants.»

However, another planetary building block does appear to linger: the gaseous parts of the disks, perhaps fostering additional growth of gas - giant planets like Jupiter for millions of years.

Simulations of the conditions in the Alpha Centauri star system suggest Earth - like planets might exist there, but gas giants are unlikely

In the Solar System, small rocky planets such as the Earth orbit near the Sun, whereas gas giants like Jupiter and Saturn are found much further out.

With their gas depleted, it may be impossible for the disks around stars in massive clusters to form giant planets like Jupiter or Saturn.

And because they are almost as cold as «gas giant» planets — Jupiter is about 150 K — studying them could offer a better handle on what the atmospheres of alien worlds look like.

Based on humankind's admittedly limited experience, habitability seems to mean a small world — a terrestrial planet rather than a gas giant like Jupiter or Saturn — orbiting its star at a comfortable «Goldilocks» distance that allows water to persist in liquid form.

In the prevailing theory of planet formation, called core accretion, dust grains stick together to form rocky worlds, and some of these rocky bodies then grow massive enough to attract surrounding gas, becoming gas giants like Jupiter.

Many of these are much larger than Earth — ranging from large planets with thick atmospheres, like Neptune, to gas giants like Jupiter — or in orbits so close to their stars that they are roasted.

As for how it was formed, astronomers are stumped as a planet of that size would usually turn into a gas giant (like Jupiter) in the early stages of formation.

K2 - 33b is a large planet like the gas giants in our solar 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).

Or, if gas giant planets like KELT - 9b possess solid rocky cores as some theories suggest, the planet may be boiled down to a barren rock, like Mercury.»

While NASA's Wide - field Infrared Survey Explorer (WISE) failed to the tell - tale warmth of gas giants like Saturn within 10,000 AUs and larger than Jupiter objects out to 26,000 AUs (NASA / JPL news release), an icy «super-Earth», would have been too cold and faint for WISE to detect — even if the hypothesized planet has a small internal heat source and absorbs some sunlight.

Most of these potential planets appear to be much smaller than gas giants (like Jupiter and Saturn).

We now know that some planets are rocky, like Earth, while others are so - called gas giants, like Jupiter.

Using a lower bound of two Earth - masses, astronomers have been increasingly relying on the label «super-Earth» for extra-Solar planets that are probably too large to be very «Earth - like,» despite their search for planets with characteristics closer to the Solar System's four rocky inner, «terrrestrial» planets than gas giants.

Unlike winds on the inner rocky planets like Earth, which are powered primarily by sunlight, winds on the gas giants are also fed by heat escaping from their deep cores, although the strength of this interior heat is a mere fraction of the sunlight falling on Earth.
