Wardwho suggested that the Moon was formed by the attractive online dating profiles impact upon Earth of a body the size of Mars.

There is no flair for it. The timescale in the gif is probably only a day or two, while the Moon would have taken months, if not years or decades, to form.

Welcome to Reddit,

This collision could potentially explain the unique geological and geochemical properties of the Moon. Estimates based on computer simulations of such an event suggest that some twenty percent of the original mass of Theia would have ended up as an orbiting ring of debris around the Earth, and about half of this matter coalesced into the Moon.

Red Dwarf showed that they behave much two planets collide simulation dating like billiard balls. Especially, the indistinguishable relation of oxygen isotopes cannot be explained by the classical form of this hypothesis.

For this scenario to be viable, however, the proto-lunar disk would have to endure for about years. One of the theories suggests that Saturn's rings have been formed by moons that got too close to Saturn and were torn apart by its gravity. After the recollision, Earth was surrounded by a disk of material, which accreted to form the Moon.

Apparently it was a moon that broke apart due to gravitational forces The relative speed of the objects should be well below escape velocity of their combined mass in order to not have most of the debris just shoot off into space.

As the two moons migrated outward from the Earth, solar tidal effects would have made the Lagrange orbit unstable, resulting in a slow-velocity collision that "pancaked" the smaller moon onto what is now the far side, adding material to the crust.

They'll bounce back eventually.

This hypothesis could explain facts that others do not. Namely, they would not meet rule 3: Nonetheless, Darwin's calculations could not resolve the mechanics required to trace the Moon backward to the surface of the Earth.

This is called the 'Roche limit'. The ratios of the Moon's volatile elements are not explained by the giant-impact hypothesis.

For example, some orbits may cause the moon to spiral back into the planet.

And so do we. Every day, we send the latest research to our 40,000+ subscribers.

Darwin's hypothesis was that a molten Moon had been spun from the Earth because of centrifugal forcesand this became the dominant academic explanation.

Thrust vectoring on an F allows for vertical take-off and landing. Okay, it's a real TV show depicting fictional events. The net effect is that it is more likely for impact-generated moons to survive when they orbit more distant terrestrial planets and are aligned with the planetary orbit.

Previously, the age of the Moon had been thought to be 4. What's the time compression on that?

Planetary collision theory

Likewise, the proximity of the planet to the star will also affect the orbital evolution. Browse WoahDude by flair. This designation was proposed initially by the English geochemist Alex N.

I'm not sure how the image is colored, either by temperature, material, or some other property.

Synestia model[ edit ] Further modelling of the transient structure has given rise to the concept of a synestiaa doughnut-shaped body that existed for a century before it cooled down and gave birth to the Earth and the moon.

The Moon-forming collision would have been only one such "giant impact" but certainly the last significant impactor event. If two bodies were to collide, they would not meet the IAU definition of a planet. The inclination of the resulting moon's orbit is random, but this tilt affects the subsequent dynamic evolution of the system.

For example, the giant-impact hypothesis implies that a surface magma ocean would have formed following the impact. Planets out of orbit are rogue. If the giant-impact hypothesis is correct, they must be due to some other cause.

None of these hypotheses can account for the high angular momentum of the Earth—Moon system. Basic model[ edit ] Simplistic representation of the giant-impact hypothesis.

Use direct links 9. It is hypothesized that most of the outer silicates of the colliding body would be vaporized, whereas a metallic core would not.
