An asteroid up to 40m in size and only discovered five days ago, is due to skim past the Earth tonight. Asteroid 2018 CB will pass by at just less than one-fifth the distance between the Earth and the Moon. It was first spotted by the Catalina Sky Survey in Tucson, Arizona, a Nasa-funded project to record potentially hazardous asteroids.
