The asteroid 2004 XP14 is expected to approach Earth on July 3. Though not exactly a doomsday scenario, the half-mile diameter rock will flyby at a distance of roughly 268 thousand miles, a hairpin in astronomical terms.
The Apollo-class asteroid (which means it has an Earth-crossing orbit), was discovered on December 10, 2004, and is classified as a Potentially Hazardous Asteroid. It will be closest to the earth at 4:25 UT on Monday.
