Sentences with phrase «collision of larger bodies»

Comets which consist of two parts, like Chury, can form after a catastrophic collision of larger bodies.

Not exact matches

These «debris disks» are constantly fed by collisions among rocky bodies — the larger of which can survive and grow by continued accretion — because the tiny dust grains quickly fall onto the central star or get blown out of the planetary system.

That level of fascination made sense in the days before telescopes could observe details in planetary atmospheres, before space probes had explored Mars and bulldozed into a comet, and before we understood the history of asteroid and comet collisions, linking celestial bodies large and small.

The rocky body — the largest yet to get a close flyby — seems to have been just large enough to avoid being reduced to a flying pile of rubble by eons of collisions with other asteroids.

The tentative verdict is that this probably is the remnant of a recent asteroid collision, where a smaller body struck a larger object at a velocity of about 15,000 kilometer per hour.

Because the blown - away material is primarily ice, this means that some large Kuiper belt objects could have been built from a small number of really big collisions among increasingly ice - depleted bodies, while others might have been formed from smaller, less powerful collisions that allowed more ice to remain.

This suggests the grains are being replenished via collisions between some number of larger bodies totaling around 1 − 6 times the mass of the Moon.

Despite their relatively youth, many A-type stars are already old enough that most of the dust found around these relatively short - lived are not a remnant of the star formation process but are instead generated through collisions of larger proto - planetary bodies.

Both objects formed among the rocky and icy protoplanets beyond the Solar System's «ice line» now located around 2.7 AUs, but the early development of Jupiter apparently prevented such large protoplanets between the gas giant and planet Mars from agglomerating into even bigger planetary bodies, by sweeping many into pulverizing collisions as well as slinging them into the Sun or Oort Cloud, or even beyond Sol's gravitational reach altogether.

«While Ceres is a lot bigger than the candidate asteroids that NASA is working on sending humans to, many of these smaller bodies are produced by collisions with larger asteroids such as Ceres and Vesta.

In her recent series Transpositions (2014 - 2016) and her latest body of photographic work titled Collisions (2016), she uses Plexiglas elements to create large - scale compositions.

Keeping in mind, the model is greatly simplified at only 3 bodies from our own actual system of interacting ocean oscillations and ocean life and ocean chemistry, terrestrial conditions and terrestrial life, solar variability, orbital variability, land use, anthropogenic aerosols, and GHGs, any of which might suffer the eventual fate of a body in the 3 Body problem: ejection or collision more rapidly with larger perturbation, and all of which are more certain to follow irregular and extreme pabody in the 3 Body problem: ejection or collision more rapidly with larger perturbation, and all of which are more certain to follow irregular and extreme paBody problem: ejection or collision more rapidly with larger perturbation, and all of which are more certain to follow irregular and extreme paths.

From the European Association of Geochemistry New isotopic evidence supporting moon formation via Earth collision with planet - sized body A new series of measurements of oxygen isotopes provides increasing evidence that the Moon formed from the collision of the Earth with another large, planet - sized astronomical body, around 4.5 billion years ago.
