A mile-long, walnut-shaped asteroid with its own moon is set to pass Earth on Saturday, according to scientists. The asteroid, known as 1999 KW4, will come within 3.2 million miles of Earth -- its second-closest approach in the past 20 years, WGRZ-TV reported. While this is considered close it’s still a safe distance from Earth.
