Thus, although it is classified as a Potentially Hazardous Asteroid (PHA) due to its size and proximity to Earth, it does not appear to pose a threat to the planet. For a period of Earth's history, between roughly 2.5 to 4 billion years ago, our planet was a punching bag for asteroids. This planet is so big that it would take around 1.300 Earths just to fill its volume! Ilona is a photo editor at Bored Panda with an MA in Communication Of Creative Society.

Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. Found inside Page 344But at that time even a small impact, with an energy release comparable to a nuclear weapon, posed a terrible danger to the human race because it could have led to war between the major powers. The danger cannot be met as popularly Scientists think the object that may have hastened the death of the dinosaurs was about seven to eight miles wide, sending a dust plume so big it engulfed the planet, igniting fires and basically broiling the dinosaurs.

Jean Paul Mertens this image and said it was seen through the telescope of Slooh.com in Chile. As we learn to maneuver a large mass like an asteroid using low-thrust propulsion and the gravity fields of Earth and the moon, we'll prove valuable technologies for the future Mars missions. But the risk of you dying in an asteroid impact might be higher than you think. It's a first-of-its-kind mission for a spacecraft to land on a large asteroid, grab a huge boulder from its surface for further study and then re-direct the asteroid into a stable orbit around the Moon.

Found inside Page 110Between 200 and 63 million years ago, the dinosaurs reigned supreme, after which the impact of an asteroid would have ended their dominance on the face of Earth by causing a 'nuclear winter.' Large volcanic eruptions that took place But in reality it could be very, very small compared to Earth. In reality, having many decades of warning gives us multiple options and multiple tries to prevent catastrophe., So if an asteroid does start flying towards Earth, well know about it well in advance.
