It could come as close as 7,000 km, say experts.

Officially designated as 2013 UG1, it was discovered by Russian astronomers using the MASTER network telescope, located close to Lake Baikal in Buryatia, Siberia. Its diameter is great than 100 metres, it is believed.
The discovery has been confirmed by US, Italian , German , Chilean and British astronomers, announced Vladimir Lipunov, head of the network, from the Moscow State University and the Sternberg Astronomical Institute. Predictions of its threat to Earth vary with some data suggesting it will miss by 194,000 km. However, the US space agency suggests 20,000 km and Italian experts say 7,000 km.
Recently scientists in the Crimea discovered another potentially hazardous 410-metre asteroid that is headed on a dangerous trajectory towards the Earth in 2032. Last month, the same team close to Baikal tracked a 'near miss' asteroid some 15 metres in diameter which came within 11,300 km of Earth.
It was 'below the orbit of geostationary satellites', said Lupunov, and 'the same size' as the meteor which exploded over Chelyabinsk in February, injuring 1,500 people, mainly from shattered glass.
