As the ring system spits out moonlet after moonlet, the small objects merge to form larger moons, which may merge in turn as they spiral outward from the planet.
The bulk of the solar system's regular satellites — those moons that stick close to their planets in roughly equatorial orbits — formed this way, rather than taking shape simultaneously with the planets as a direct result of planet formation, French astrophysicists have concluded.
To find out, Jian Ge of the University of Florida in Gainesville and colleagues built a computer simulation of the system, which showed that moon - sized protoplanets — the precursors to larger worlds — could indeed form after about a million years.
Through footage from NASA missions, viewers also visit those places in our solar system most likely to harbor elusive life - forms, including Mars and the moons Titan, Io, Europa, and Enceladus, and explore analogous habitats found right here on Earth.
[In our own solar system, for example, it is possible that areas beneath the ice of Jupiter's moon Europa or in the geysers of Saturn's moon Enceladus might support some form of life.]
A plausible explanation for the myriad Plutonian moons, Showalter says, is that «this system began when something big hit Pluto billions of years ago — it created this big cloud of debris, most of which condensed to form Charon.»
In its wake, the collision left a planetary disk that formed the moon and sent bits of proto - planet flying into our solar system's main asteroid belt.
The new hypothesis also explains how Saturn's moons that orbit just beyond the edge of today's ring system might have formed.
The presence of water in liquid form still guides our searches for extraterrestrial life: on Mars, on the moons of Saturn and Jupiter or on extrasolar planets (beyond our Solar System).
The fragments of that final doomed moon, each originally between 1 and 50 kilometers across, formed an icy ring system as much as 1000 times as massive as today's rings.
«The discovery of this moon reinforces the idea that the Pluto system was formed during a massive collision 4.6 billion years ago,» says discovery team member Hal Weaver of Johns Hopkins University's Applied Physics Laboratory in Laurel, Maryland.
«The process is so efficient that 20 to 30 generations of moons could have formed» since the solar system's birth, says Charnoz.
Esposito thinks this was early in the solar system's history, and that the rings have gradually spread since then, perhaps forming moons in the process.
«The model we propose is the least restrictive impact scenario,» Canup says, «since it involves only a single impact and requires little or no modification of the Earth - Moon system after the Moon - forming event.»
If an accompanying moonlet formed in the aftermath of that collision, simulations have shown, the system would be unstable, pushing the moonlet into a sudden demise in a collision with the dominant moon or with Earth.
Understanding how the moons of our solar system came to form significantly improves scientists» understanding of the formation processes that sculpted the planets that they now orbit.
Kamuela, HI — Combining observations from the world's largest telescopes with small telescopes used by amateur astronomers, a team of scientists discovered that the large main - belt asteroid (87) Sylvia has a complex interior, thanks to the presence of two moons orbiting the main asteroid, and probably linked to the way the multiple system was formed.
This is the sequence: Superclusters form the top level, followed by clusters, galaxies, nebulae, star systems, stars, planets and moons.
A UCLA - led research team reports that the moon is at least 4.51 billion years old and probably formed only about 60 million years after the birth of the solar system — 40 million to 140 million years earlier than had been thought.
Still other moons were probably formed from material left over when the planets were formed in the early days of the solar system.
-- to explore the Solar System beyond Mars to understand how giant planets and their moons form and evolve, to search for habitable environments on and within moons (like Enceladus, Europa and Titan), and to examine the farthest bodies in the solar system for clues to the early history of the solar sSystem beyond Mars to understand how giant planets and their moons form and evolve, to search for habitable environments on and within moons (like Enceladus, Europa and Titan), and to examine the farthest bodies in the solar system for clues to the early history of the solar ssystem for clues to the early history of the solar systemsystem.
Well, almost encloses: Enceladus sprays geysers of water ice out into space, some of which settles back down to the moon's surface in the form of snow, making it the most reflective planetary object in the solar system.
The leading theory for Charon's formation is that it formed similar to the way that the Earth and Moon have formed: from the accumulated orbital debris that surrounded Pluto after a giant impactor hit the latter during the early history of the Solar System.
«It will help us learn how rocky bodies form, including Earth, its moon and even planets in other solar systems.»
