Asteroid nearly a mile wide seen approaching with its own moon

A "potentially hazardous" asteroid and its smaller sidekick have been spotted from the ground coming in for flyby of our planet that will see the space objects pass by us safely on Friday.

The unnamed space rock designated as Asteroid (66391) 1999 KW4 is a binary system, meaning it's composed of one large asteroid orbited by a smaller moon. The larger half of the duo is nearly a mile (1.5 kilometers) wide, while its smaller satellite is about a third of a mile wide (0.5 kilometers). The asteroid was first discovered 20 years ago, and both backyard and professional astronomers are preparing to observe it as it makes its latest close approach May 25.
