Massive asteroid will fly by Earth on 31 May

Los Angeles Times : Asteroid 1998 QE2 measures 2.7 km across and is covered in a black, sooty material. It’s also on course to come within 5.8 million km of Earth on 31 May, just before 5 pm EDT. The close approach will give astronomers the chance to study the asteroid’s shape, rotation, and surface. Features as small as 3.5 meters should be resolvable by radio telescopes. Backyard astronomers, however, won’t be able to see it.
