Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those in co-orbit with Jupiter.
There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth asteroids. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbon-rich, metallic, and silicate (stony) compositions, respectively.
● Discovery Channel - Large Asteroid Impact Simulation (2008). Earth was born as a result of repeated asteroid collisions, the moon was created by a single giant impact event. Then, Earth's size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapour to cover the entire surface and evaporate all ocean water. The earliest life-forms survived such infernal events by escaping deep into the ground, miraculously emerging again and again. The Earth has gone through innumerable catastrophic events, and life has survived by acquiring new abilities to live through each crisis. Humans are part of the grand history of life's evolution, which has been closely intertwined with repeated cataclysmic events. Learn what would happen if an asteroid hit the Earth with t...

Welcome to Top10Archive! Everyday that mankind gets to enjoy life to its fullest is a day where mankind is paying no mind to the dangers that threaten them from space. Minor planets and planetoids threaten the very existence of Earth on a frequent basis - so frequent, in fact, that it is scary. Over the past several decades alone, the people of Earth have been threatened by a slew of asteroids - and these ten are amongst the most life-threatening, should they have changed trajectory and slammed into the blue planet. To put these distances into perspective, our moon is roughly 239,000 miles or 384,000 kilometers from earth.

Now that we’ve finished our tour of the planets, we’re headed back to the asteroid belt. Asteroids are chunks of rock, metal, or both that were once part of smallish planets but were destroyed after collisions. Most orbit the Sun between Mars and Jupiter, but some get near the Earth. The biggest, Ceres is far smaller than the Moon but still big enough to be round and have undergone differentiation. CORRECTION: In the episode we say that 2010 TK7 is 800 km away. However, 2010 TK7 stays on average 150 million kilometers from Earth, but that can vary wildly.

Meteors, Asteroids, Meteorites and Fireballs sightings compilation from around the World over the last couple of years with the latest Asteroid to come close to earth named Asteoid 2013 TX68. This was predicted to arrive and fly by earth on March 5 2016 but the date has been moved forwards by some to March 8 2016. Distance from earth as it flies by is variable based on current calculations. Chance of impact is unlikely but can't be ruled out. Other meteors and fireballs featured are a couple over Thailand both at day and at night, some over Europe, the famous Russian meteor that impacted in 2013, Texas and California meteors and the recent Scotland Meteor sighting in February 2016. Are these meteors and asteroids a warning of End Times and Bible Prophecy and what is to come, or is it bus...
Learn the difference between an asteroid, comet and meteor. Our dear planet Earth is the hotbed of cosmic activity this year. Let's recap some recent news - a meteor explodes over Russia, an asteroid barely missed crashing into Earth, and later this year, we will see a comet in the skies that will shine brighter than full Moon. Asteroids, Comets, Meteors - ever wonder the difference among those 3 celestial bodies? Asteroids are usually made from space debris like rock, although some are comprised of nickel or iron. The bodies range in size from a boulder to hundreds of miles in diameter. They orbit around the sun. Some asteroids have struck the Earth in the past, but most don't survive passing through our planet's atmosphere. Comets are essentially space's equivalent to snowballs. U...

http://mocomi.com/ presents: What are Asteroids? Asteroids are celestial bodies that orbit around the sun. The word asteroid means star-like and is derived from the Greek words – astor (star) and oid (shape). They are believed to be remnants of the humungous cloud of dust and gases that formed the sun and planets over 4 billion years ago. Most of them lie in a single belt between the orbits of Mars and Jupiter. Sometimes changes in gravitational flows and other forces in space cause them to get dislodged from their orbit and move away from the main belt. It is believed that a giant asteroid crashed into earth millions of years ago, causing extreme changes in weather and the extinction of dinosaurs. Scientists believe that the asteroid belt in our solar system could have formed in one of...
Impact Craters on Earth, Moon and other planets provide evidence that the Earth has been struck by asteroids since it formed roughly 4.5 billion years ago. Once every few million years, an object large enough to threaten life on Earth comes along. Meteorite specialist Denton Ebel, Curator in the Division of Physical Sciences, provides a brief history of impacts from the early days of the solar system to the impact that might have led to the demise of most dinosaurs on the planet. ASTEROID CRASH COURSE Asteroids can be hazardous to life on Earth, but they also provide clues about the early solar system. In the Asteroid Crash Course video series, Denton Ebel, curator in the Museum's Division of Physical Sciences, explains how asteroids formed and the varying degrees of destruction they c...
A million miles away
We can run, we can be lost in space
Counting down from ten
With a spark we can start our life again
Who says we can't fly, fly away
Who says we can't run, run away...
With the asteroids!
Writing off our friends
All alone we are lost again
Writing off our pain, cause we run, run away...
With the asteroids!
Please don't you ever crash, or or fly or stay in space
Please don't you ever crash, or or try and save the day
Away and away and you watch me
Touch down, I won't stay
Away and away and you want me...to stay
Counting down the days
We can run, we can be lost in space
Falling off the end
With a spark we can start our life again
Who says we can't fly, fly away
Who says we can't run, run away...
With the asteroids!
Please don't you ever crash, or or fly or stay in space
Please don't you ever crash, or or try and save the day
Away and away and you watch me
Touch down, I won't stay
Away and away and you want me...but I cannot stay!!
Release my wings, please cut these strings
So I can fly, and fly, and fly...away
She says she wants me to stay
She says she wants me to stay
She says she wants me to stay
