NASA has lately warned about a potentially dangerous, peanut-shaped asteroid which may slam Earth one day. Dubbed as 2015 BN509, the asteroid is 200 meters (660ft) wide and 400 meters (1,310ft) long. The space rock was found to pass by Earth at a distance of 70,500km (44,000mph) last week. The closest proximity between the Earth and the asteroid was equal to 14 times the distance between the Moon and Earth.
