A rock hurtling through space will make a close encounter with Earth on Saturday, according to Nasa.  But don’t cancel the BBQ just yet – it’s unlikely to smash into our planet. If it did, it could potentially wipe out life as we know it. So Nasa is keeping an eye on it just in case. The asteroid – named 441987 (2010 NY65) – is marked as a concern because it’s 230

metres in diameter and traveling just 7.9 lunar distances (that’s about three million km) from us. If it were to strike, its weight could impact with a force 300 times greater than the Hiroshima bomb, scientists have predicted. 2010 NY65 was discovered on July 10, 2010, by the Wide-field Infrared Survey Explorer (WISE) spacecraft and is expected to make yearly close approaches to Earth until 2022.  READ MORE
