A little context. A better view.
Two objects can look close together from Earth while remaining far apart in space. Angular separation describes their apparent spacing, not their physical distance.
An outer planet at opposition lies opposite the Sun in our sky. It is generally well placed during the night; its altitude and your weather still shape the observing opportunity.
Greatest elongation can make Mercury or Venus easier to find in the evening or morning. A low horizon and local twilight conditions are important, even when the separation is large.
Some conjunctions occur close to the Sun. The event page preserves that distinction. Never sweep near the Sun with binoculars or a telescope to find a planet.
