Early in the morning of 12 August, two of our brightest planets, Venus and Jupiter will appear close together in the early sky. This will be a rare chance to observe two of our brightest planets side by side. 

Venus will outshine Jupiter with its white glow, while Jupiter will appear more golden. With a small telescope or a pair of binoculars, you might able to see Jupiter’s banded atmosphere and its four Galilean moons.
