Duck! 18th April – 3 days’ time

Be warned – an asteroid as big as the Rock of Gibraltar will streak past Earth on Tuesday 18 April at an uncomfortably close distance, according to astronomers.

Although there is no possibility the asteroid will collide with our planet, this will be a very close approach for an asteroid this size, NASA said in a statement. Dubbed 2014-JO25 and roughly 650 metres across, the asteroid will come very close after having looped around the Sun. 2014-J025 will then continue on past Jupiter before heading back toward the centre of our Solar System. In Durban you need to duck at 8.17pm that night, and in Tshwane at around 8.21pm. Don’t forget.
