What does opposition mean for an outer planet?

Opposition is when Earth passes directly between the sun and an outer planet, placing the outer planet on the opposite side of the sky from the sun.

The ecliptic is the sun’s path in our sky

The ecliptic is the path the sun takes across our sky. It's the Earth-sun plane, and, more or less, the plane of our solar system.

See the Venus-Jupiter conjunction on August 12

A conjunction is when 2 objects share the same right ascension. The Venus-Jupiter conjunction of August 12 is a great one for observation!
