Dots display positions
of Galilean satellites at
4 A.M. EST on the date
shown. South is at the
top to match
the view
through a
telescope.
To locate the Moon in the sky, draw a line from the phase shown for the day straight up to the curved blue line.
Note: Moons vary in size due to the distance from Earth and are shown at 0h Universal Time.
