Could these worlds be the extreme cousins of gas giant Jupiter? "Hot Jupiter" is the term that astronomers use to refer to massive extrasolar gas giants -- close to or larger than Jupiter -- that orbit within about 0.05 AU (astronomical units, or Earth-Sun distances) of their home star, about one-eighth the distance between Mercury and the Sun, or less than about 9 million kilometers (6 million miles). Well, hotter than they should be, for being so far from the sun. This is an artist's concept of the Juno spacecraft in front of Jupiter. Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different … Hot Jupiters are huge worlds made of gas that are heated to high temperatures by their star. Basically, these are gas giants which orbit in close proximity to their stars. Hot Jupiters are fairly exotic, at least by the standards of our Solar System, with some of these sweltering worlds possibly having clouds of molten rock scudding through their skies. more from Astronomy's weekly email newsletter.

The recent discovery of particularly low density gas giants orbiting red giant stars supports this theory. New research presented at the 233rd Meeting of the American Astronomical Society in Seattle, Washington, on January 8 lends credence to an idea that goes against previous thoughts about planet formation, but has been gaining traction in the field: Giant planets that orbit their stars in a matter of days may have formed in place close to their suns, rather than moving inward from much farther away. It is very likely that in the Solar System Jupiter will become a hot Jupiter after the transformation of the Sun into a red giant. The gas planet likely has three distinct cloud layers in its "skies" that, taken together, span about 44 miles (71 kilometers). More than 1,000 Earths would fit inside Jupiter.

The innermost layer may be made of water ice and vapor. Migration of hot Jupiters can be caused by different mechanisms. To make a hot Jupiter, first you must form a gas giant. Learning what Jupiter is made of and how it works will tell us more about the rest of the solar system and our own planet, Earth. Determining how these solar systems — and ours — formed is challenging. But the famous storm is filled with plenty of mysteries. Saturn and Jupiter are two planets in our solar system that have plenty of differences between them when it comes to their nature and characteristics. But unlike Jupiter, which is five times as far from the Sun as Earth and orbits the Sun in 12 years, 51 Peg is twenty times closer to its star than Earth is to the Sun and orbits its star every 4 days. This i… How does the transit method work? Jupiter does not have a solid surface, and the lowest atmospheric layer, the troposphere, smoothly transitions into the planet's fluid interior. Jupiter, on the other hand, is located 778.5 million km from the Sun and takes 11.86 years to complete a single year.
