According to Laughlin, the formation of giant planets like Jupiter is somewhat rare but, when it occurs, the giant planet usually migrates inward and ends up at an orbital distance similar to Earth's.
Water is thought to play an important role in the formation of giant planets, since comet-like bodies bombard young planets, delivering most of the water and other molecules that we can observe," said Jonathan Fortney, a member of the team from the University of California, Santa Cruz.
The amount of water in the giant planets of our solar system is poorly known because water that has precipitated out of the upper atmospheres of cool gas giant planets like Jupiter is locked away as ice.
48 billion miles from Neptune -- nearly 27 times the distance between the Earth and our sun -- as it crosses the giant planet s orbit at 10:04 p.
This supports the idea that the star originally had a full complement of terrestrial planets, and probably gas giant planets, orbiting it - a complex system similar to our own.
Minutes- or hours-long eclipses of the star by the giant planet would be a frequent occurrence.
And that's important because it sets a constraint on how quickly giant planets migrate inward.
It will learn how much water the giant planet holds, what triggers its vast magnetic fields and whether a solid core lies beneath its dense, hot atmosphere.
As telescopes get better and more space probes visit the giant planets, we will be able to count these planets' smaller moons.
In partnership with astronomers in Australiaand the US, the programme aims to detect planetary systems like our own -with giant planets in long near-circular orbits and small rocky planets on shorter near-circular orbits.
Giant planets like Jupiter were formed in just a few hundred years, not several million as was previously thought, according to a study published yesterday.
European astronomers said they had located dozens of giant planets in three distant solar systems.
Chapters discuss color choice and how to draw common shapes such as spheres, show how to use real images from Earth and space, and detail features of the earth-like and gas giant planets.
We study giant planets to look inside at ourselves and to look far away," Atkinson says.
Further study is motivated not only by fundamental interest but also because experiments may shed light on the physics of dense cores of gas giant planets like Jupiter, or guide efforts to create anti-hydrogen through the recombination of positrons and anti-protons.
