Asteroid big enough to end human civilisation expected to pass close by Earth

An asteroid measuring four kilometres wide and big eugh to potentially end human civilisation is expected to pass close Earth in April. According to reports, NASA is closely monitoring colossal rock, estimated to measure up to 2.5 miles (4.1 km) across, and has officially named it as 52768 (1998 OR2). asteroid is projected to pass earth on April 29 at a speed of 31,320kmh and will be closest at just  0.04205 astromical units away from our planet.

Meanwhile, a massive asteroid that is bigger than world's tallest building sail past Earth on February 15, according to NASA. giant rock dubbed 163373 (2002 PZ39) measuring between 1,400 and 3,200 feet in diameter is based on object's magnitude, as per data from ncy's Center for Near-Earth Object Studies (CNEOS). scientists suggested that asteroid would stand higher than Burj Khalifa skyscraper in Dubai, which is tallest structure on Earth. 2002 PZ39 is about to make its close approach at 11:05am Universal Time (6:05 am EST) on February 15.

It zoom past Earth at a distance of around 3.6 million miles i.e. 15 times distance between Earth and moon. asteroid crossed at a speed of nearly 34,000 miles per hour which is about 20 times as fast as an F-16 jet fighter flying at maximum velocity. In dition, asteroid is defined as a "potentially hazardous" near-Earth object (NEO) by CNEOS.
