- But, the 2013 flyby is by far the closest the asteroid will approach our planet for many decades. The next notable close approach to Earth will be on February 15, 2046, when the asteroid will pass no closer than 620,000 miles (1,000,000 kilometers) from the center-point of Earth.

EXCLUSIVE: These THREE asteroids REALLY could HIT Earth and 'wipe out life' GETTY•NASA. Two of the hulking asteroids could even strike our planet in YOUR grandchildren's lifetime, NASA and the European Space Agency have admitted. The cosmic boulders are on a NASA list of potentially-hazardous asteroids (PHAs) that actually pose a real risk of hitting us.

- The surreal scene after a massive asteroid hit Earth 3.26 billion years ago. By Paca Thomas. New research chronicles a 23-to-36-mile-long asteroid that slammed into Earth about 3.26 billion years ago. The impact had a devastating effect on the planet, triggering a 30-minute-long earthquake, boiling the oceans, and lighting the sky on fire.

Nasa plans landing on 280,000mph asteroid travelling towards the Earth Nasa plans landing on 280,000mph asteroid travelling towards the Earth. Nasa is planning to land spacemen on an asteroid that is travelling at 28,000mph towards the earth, it emerged today. The rock, which was once considered the most dangerous object in the universe with the explosive power of 84 Hiroshimas, will narrowly miss our planet in 60 years' time.

- Meteor (1979) features small asteroid fragments and a large 8 km (5 mi)-wide asteroid heading for Earth after being wrenched out of orbit by a collision with a comet. Orbiting U.S. and Soviet nuclear weapons platforms are turned away from their respective earthbound targets and toward the incoming threat.

- When a meteoroid, comet or asteroid enters the Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake.

- Those sorts of predictions typically stem from computer models, which sometimes suggest that, during this or that meteor shower, Earth will encounter a particularly rich stream of particles in space. Meteor showers are caused by debris left behind in the orbits of comets.

- Since asteroids orbit in the same direction around the sun as the earth does, they approach at a slow speed. When an asteroid approaches earth, it gets accelerated by the earth’s gravity and when it hits the atmosphere, various factors determine its speed, including the shape and size as well as air resistance.

SHOCK ASTEROID WARNING: Planet earth faces 100 YEARS of killer strikes starting in 2017 He said there is an asteroid with our name on it and it is only a matter of time before an asteroid large enough to wipe out the human race collides with Earth. Many believe an asteroid was responsible for killing the dinosaurs with a similar life-changing event potentially just around the corner.

- Apophis is a near-Earth asteroid that caused a brief period of concern in December 25-27, 2004, because initial observations indicated a relatively large probability (up to 2.7%) that it would strike the Earth in 2029.

Meteoroid When a meteoroid, comet or asteroid enters the Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. meteoroid is a small rocky or metallic body travelling through space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to 1 meter-wide objects.

What if an asteroid hit the Earth? An asteroid impact is also the stuff of science fact. There are obvious craters on Earth (and the moon) that show us a long history of large objects hitting the planet. The most famous asteroid ever is the one that hit Earth 65 million years ago.

NASA Finally Discusses Sept. 2015 Comet/Meteor/Asteroid Doomsday Prediction A spokesperson from NASA said that the agency is not aware of and is not tracking any comet or asteroid which is on a collision course with Earth in the month of September 2015.

How Earth is protected from harmful radiation High above Earth’s atmosphere, electrons whiz past at close to the speed of light. Such ultrarelativistic electrons, which make up the outer band of the Van Allen radiation belt, can streak around the planet in a mere five minutes, bombarding anything in their path. Exposure to such high-energy radiation can wreak havoc on satellite electronics, and pose serious health risks to astronauts. Now researchers at MIT, the University of Colorado, and elsewhere have found there’s a hard limit to how close ultrarelativistic electrons can get to the Earth.

Impact Craters in the Solar System Comets and asteroids strike the Earth and Moon at a wide range of impact speeds, with 20 kilometers per second being typical. Such a high-speed impact will produce a crater that is 10 to 20 times larger in diameter than the impacting object. The detailed form of the crater depends on its size.

- Not all asteroids are in the Asteroid Belt. Sometimes collisions between asteroids, combined with the gravitational effects of Jupiter, can cause asteroids to leave the belt. If an asteroid comes within 1.3 AU (121 million miles) of the Sun, it is called a Near-Earth Asteroid (NEA).bout 2-4 AU (186-370 million miles) away from the Sun, between the orbits of Mars and Jupiter, is a region called the Asteroid Belt. This region is a ring of tens of thousands of relatively small rocky objects called Asteroids. Asteroids can vary greatly in size.

- 1937 -- Asteroid Hermes -- about a kilometer in diameter -- misses Earth by 600,000 miles. Hermes, although smaller than the 'roid that snuffed the dinosaurs, could have been a true category killer, able to cause epic devastation and kill millions.

Mars Mission May Carry Asteroid-Smashing Probe in 2016 FLAGSTAFF, Ariz. — When a NASA mission to study Mars' deep interior blasts off in 2016, it may also carry a tag-along experiment that will slam an impactor into a potentially hazardous asteroid.he Osiris-Rex spacecraft is scripted for travel to 1999 RQ36, a near-Earth carbonaceous asteroid. The probe will rendezvous with that space rock in 2019-2021, gathering and returning specimens of the object for delivery to Earth in 2023.

10 Biggest Asteroid Craters on Earth An estimated 580 million years, an asteroid slammed into the stony hills of what is now part of South Australia, creating the 56-mile wide Acraman crater. Nothing like a simple round shaped crater, many believe that the impact caused a widespread disturbance to life on Earth.

When Will the Earth Get Hit by Another Asteroid? Big impacts are rare. The Chelyabinsk asteroid was 19 meters (62 feet) in diameter, and, on average, we should expect an impact from an object that size somewhere on Earth about once every 25 years. (Because most of the planet is covered in water, many of these go unnoticed.) A small chunk of Chelyabinsk meteorite, given to me by a friend.

Small asteroid discovered orbiting Earth And some scientists think there could be other mini-moons orbiting the Earth -- some permanent and some temporary. In 2012, researchers using a super computer concluded that at any given time there should be at least one asteroid with a diameter of at least one meter orbiting Earth..

SHOCK ASTEROID WARNING: Planet earth faces 100 YEARS of killer strikes starting in 2017 Most will have a maximum diameter of around 100 metres-the size of seven double decker buses-and the potential to cause significant damage. But concerned scientists warned a colossal monster is also heading our way, with one 'mega' asteroid threatening earth in just SIX years.

How Do Diamonds Form? When these asteroids strike the earth, extreme temperatures and pressures are produced. For example: when a six mile (10 kilometer) wide asteroid strikes the earth, it can be traveling at up to 9 to 12 miles per second (15 to 20 kilometers per second).

- 1.) They tell us about the origins of our solar system. Asteroids are the leftover debris from the creation of our solar system. 2.) Sometimes a collision in the asteroid belt can send a large rock hurling towards earth.It if collides, all life on earth could be effected depending on how big the impactor is.omets, asteroids and meteorites are all leftover pieces of rock from the formation of our solar system. Astronomers get clues of how the early universe was like, by studying … the sizes, locations, chemical composition of the 'space rocks'.
