It will be a treat for sky gazers on Monday as a recently discovered Asteroid 2011 MD will be passing by extremely close to the earth - at a distance of only 10,000-12,000 km. Experts say that it will be visible in India. Discovered on June 22 this year, the asteroid is estimated to be 8 to 18 metres long. It will pass by the earth on June 27 at 6.56 pm.
