Transcript of Asteroids

An asteroid are bodies of rock, ice and other minerals and ores that float through space. The minerals are generally iron and ice, but can also be more rich in minerals, like with gold and magnesium.
Cool Facts!
The Moon was created by an asteroid hitting the earth millions of years ago in it's early life.
Many car sized asteroids fall into Earths atmosphere every year.
Most asteroids lie in the Asteroid Belt, which is located in between Mars and Jupiter
Some asteroids are actually burnt out comets. They don't accelerate at a very high velocity, like they used to, due to collision or gravitational pulls.
Some asteroids have moons of their own!
Asteroids are also referred to as minor planets or planetoids.
While asteroid impacts were frequent in the past during the Universes creation, but there hasn't been many recently.
100 tons of space dust and rock fall towards the Earth everyday, but disintegrate in the atmosphere as they experience great friction on their speedy entries in.
Nearly 65 Million years ago the entire Dinosauria Clade was killed off by a metorite. Except for one species of Dinosauria. Birds.
Comet 67P was landed on by satellite Rosseta almost a year ago, courtesy of the European Space Agency.
Q: Why haven't we been killed by a large asteroid hitting the Earth yet?
A: Most asteroids that enter the Earths atmosphere disintegrate in the atmosphere. Although the last asteroid that could of made us extinct was predicted to arrive in the 2030s, but arrived in 2014. Just shows how inaccurate some highly scientific measurements actually may be.

Who ever threw that paper, your mom's a hoe!
Q: Why did the EU spend precious government dollars on a comet landing?
A: Earth doesn't have unlimited resources, and never will. The reason we even have the precious metals and minerals we cherish on Earth is because our planet was created with asteroids colliding that had these materials. We need to be able to extract resources from asteroids and eventually comets if we want to stay here as long as possible.
Q: When did the last asteroid/meteor hit Earth?
A: The last asteroid landed on Earth in 1908 but missed civilization and killed one-thousand deer in the Siberian Forest, but never hit the ground, so there's is no crater. It disintegrated in the atmosphere but low enough it caused a large explosion.
Q: What was the last asteroid that came closest to destroying Earth?
A: In 1937 Asteroid Hermes missed Earth by 965 606 km. (This may seem far, but it isn't in space) Although smaller than the asteroid that killed the Dino's, it could have killed millions on Earth, and would come with long term effects.
