It is a very rare event in the sky on Monday when Venus, Jupiter and moon combine to create a smiley face. This rare astronomical phenomenon is known as "Planetary Conjunction". People in U.S can see on west horizon around sunset with naked eye. On 1st they will be so tightly packed to form a face. Venus is 93 million miles from Earth but it shines with a brilliance that people have mistaken for UFO. Jupiter is currently about 472 million miles away from earth.
