NASA tracks 44ft asteroid approaching Earth
A house-sized asteroid is set to pass by Earth on Sunday, 19 March, according to NASA’s Jet Propulsion Laboratory (JPL). The asteroid, named 2016 WH, is not posing any threat to the planet because it will pass by if it continues on its trajectory. Measuring between 11 metres and 24 metres in diameter, the asteroid will pass at its closest point at a distance of 6.93 million km, travelling at a speed of 42372 km/h. NASA has deployed Earth and sky-based technologies including satellites and telescopes to track the movements of asteroids to determine which pose a threat.
