    Giant pyramid-shaped asteroid to shoot past earth in hours

    A 427-foot pyramid-shaped asteroid is due to fly by Earth on Sunday, scientists say.

    According to the Centre for Near-Earth Object Studies at Nasa’s Jet Propulsion Laboratory, the object, called VH5 2019, will harmlessly fly past around 4.27 million miles from our planet at a speed of 6.1 miles per second.

    At 187ft by 426.5ft, the asteroid is “pyramid-shaped" and almost as large as the Great Pyramid of Giza.

    The asteroid is one of five due to fly past Earth over the weekend, all at safe distances.

    2000 years between Football field sized asteroids and we are due for a hit... Could wipe out a whole city instantly... unless we can deflect it.


    What killed the dinosaurs wa a large asteroid or comet about 11 to 81 kilometers (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth.

    The closest known approach of Apophis comes on April 13, 2029, when the asteroid comes to within a distance of around 31,000 kilometers from Earth's surface. As of 2014, the diameter of Apophis is estimated to be approximately 370 metres (1,210 ft).

    The largest known Potentially Hazardous Asteroid (PHA) is (53319) 1999 JM8 which is actually only 7 km in diameter. Its next closest approach in the 21st century will be in 2075 at 0.256 AU 0.256 au (38,300,000 km; 23,800,000 mi) and in August 2137 at 0.0764 au (11,430,000 km; 7,100,000 mi).[1] For comparison, the planet Venus is about 40 million km (25 million mi).
