"The Two Inferior Planets Meet on the Summer Solstice, the First Day of Summer"

Scheduled air date: 2003 Jun 02-08


In the morning sky, the two inferior planets—those whose orbits are closer to the Sun than our own—Mercury and Venus, can be seen in the east.  With each morning they will appear closer to each other, until they are only four-tenths-of-a-degree apart on the morning of June 21st.  They will then separate, growing farther apart with each morning.
(Shown about 40 minutes before sunrise for mid-northern latitudes.)
