The actual conjunctions, the two planets’ closest approach to one another, occurs before they rise right before dawn. At conjunction, they are separated by .2 degrees. Their separation will have increased to .5 degrees, the width of the full Moon, and will still present a pretty pair when they rise in the east shortly before sunrise.
The two largest asteroids, Ceres and Vesta will reach a very close conjunction on July 4th and 5th. On these two nights they will appear within 10 arc minutes of one another. As points of reference, there are 60 arc minutes in a degree, and the Moon’s apparent diameter is about 30 arc minutes, or as previously stated, 1/2 degree in diameter. These two bodies are not visible with the unaided eye, but can be seen with binoculars or a modest telescope. The conjunction will occur in Virgo, but do your research to know exactly where to look, and print out a chart with stars down to 9th magnitude.
