An asteroid with a diameter of 400m will make its closest approach to Earth later this year. Known as YU55, the asteroid would fly within the moon's orbit narrowly missing Earth, according to reports. "The space rock will hurtle past our planet at a distance of just 201,700 miles (324,600km) during its closest approach on November 8," The Daily Mail has reported.

Apophis is an asteroid with an slightly offset orbit to that of Earth's. Discovered in June 2004, astronomers have determined that it will make a very close flyby on Friday, April 13th, 2029, where it will pass to within 5 Earth diameters of us. The exact path the asteroid follows on its flyby in 2029 will determine whether it smashes into the Earth seven years later. In 2004, it was first thought that the asteroid would hit us in the first flyby in 2029. The initial calculation for the orbit was made using only two sets of observations, those made in June and a subsequent set made in December.
