On June 8, the 370-meter (about 1,300-ft.) asteroid 2014 HQ124 breezed by Earth at a distance of just 800,000 miles (1.3 million km). Only hours after closest approach, astronomers used a pair of radio telescopes to produce some of the most detailed images of a near-Earth asteroid ever obtained. They reveal a peanut-shaped world called a ‘contact binary’, an asteroid comprised of two smaller bodies touching. About one in six asteroids in the near-Earth population has this type of elongated or “peanut” shape.

The asteroid 2014 HQ124, which is the size of a football stadium, poses no chance of hitting Earth in its flyby on Sunday (June 8), and will pass by at a range of three times the distance between the Earth-moon on Sunday (June 8). It was discovered on April 23 by NASA's Wide-Field Infrared Survey Explorer, a sky-mapping space telescope. This afternoon, the online Slooh community observatory will host a live webcast preview of asteroid 2014 HQ124, beginning at 2:30 p.m. EDT (11:30 a.m. PDT/1830 GMT) at its website: http://www.slooh.com.
