Bob Bello, WikiCommons Hold your breath. A massive asteroid called Apophis after the ancient Egyptian god of chaos is hurtling towards us and will sneak past us on Friday and Saturday. According to earthsky.org this flyby is a precursor to the “tantalizingly close sweep” Apophis will make in 2029. Apophis is plummeting towards earth at 4.658 kilometres per second. But don’t worry too much just yet. Earthsky.org says while there’s no chance Apophis will strike Earth at this flyby (when closest, it’ll be about 44 times the moon’s distance), the asteroid will be within range of earthly telescopes and radar.
