Sentences with phrase «giant planet migrations»

This work sheds light on the complex youth of our solar system, when the building blocks that formed the core of giant planets and their satellites were tossed around or captured during the giant planet migrations.

The giant planet migration shook up the asteroid belt, removing many bodies, possibly including the parent of this family.»

Not exact matches

Such orbital migration would destroy any smaller, Earth - like planets that had formed, as an inward - moving giant would scatter smaller planets the way a bowling ball would blast through a pile of marbles.

The answer, according to theorists, is planetary migration: dramatic orbital changes due to the gravitational interaction of the young giant planet with the remains of the disk, or mutual interactions between planets.

The orbits of exocomets on Beta Pictoris could also help scientists trace the presence and migration of larger, undetected bodies such as gas giant planets in the planetary system, says Russel White, an astronomer at Georgia State University in Atlanta who was not involved in the study.

The discovery of a very young hot Jupiter thus confirms that early migration within the disk also applies to giant planets.

Theoretical models predict that migration occurs either early in the lives of giant planets while still embedded within the protoplanetary disk, or else much later, once multiple planets are formed and interact, flinging some of them into the immediate vicinity of their star.

In our solar system's youth the gas giant's footloose migration toward and away from our star flicked aside lesser worlds — a pruning that, as brutal as it was, opened up space for our planet.

Alternatively, the planet could be evidence against the migration theory, suggesting that giant planets can in fact form close in to their stars.

None of the approximately 750,000 known asteroids and comets in the Solar System is thought to have originated outside it, despite models of the formation of planetary systems suggesting that orbital migration of giant planets ejects a large fraction of the original planetesimals into interstellar space1.

The present study focused on the period called the Late Heavy Bombardment that is believed to have occurred 4 billion years ago in our solar system, when the giant planets underwent orbital migration.

One theory suggests, however, that its extreme tilt could have been created by a series of smaller shifts through orbital migrations and interactions between the giant planets during the earliest stages of Solar System formation (Adrián Brunini, 2006).

On December 1, 2009, two astronomers submitted a pre-print suggesting that the planet's extreme axial tilt (an obliquity of 97 degrees) may have resulted from the presence of a large moon that has since been ejected from orbit around the ice giant by the pull of another planet during the orbital migration of the giant planets early in the formation of the Solar System.
