Collision Earth is a Canadian disaster television film directed by Paul Ziller. [1] It was released in 2011 for broadcast on the Syfy Channel and later distributed by Anchor Bay Entertainment on Blu-ray.
In contrast, evidence published in January 2016 suggests that the impact was indeed a head-on collision and that Theia's remains are on Earth and the Moon. [ 14 ] [ 15 ] [ 16 ] Simulations suggest that Theia would be responsible for around 70-90% of the total mass of the Moon under a classic giant impact scenario where Theia is considerably ...
Artist's depiction of a collision between two planetary bodies. Such an impact between Earth and a Mars-sized object likely formed the Moon.. The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.
Models developed in 2018 to explain the unusual spin of Uranus support a long-held hypothesis that this was caused by an oblique collision with a massive object twice the size of Earth. [ 122 ] Observed events

A collision zone occurs when tectonic plates meet at a convergent boundary both bearing continental lithosphere.As continental lithosphere is usually not subducted due to its relatively low density, the result is a complex area of orogeny involving folding and thrust faulting as the blocks of continental crust pile up above the subduction zone.
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids.)
In 1998, NASA formally embraced the goal of finding and cataloging, by 2008, 90% of all near-Earth objects (NEOs) with diameters of 1 km or larger that could represent a collision risk to Earth. The 1 km diameter metric was chosen after considerable study indicated that an impact of an object smaller than 1 km could cause significant local or ...
