For the rest of the planets, there can only be one conjunction on the far side of the sun. These planets can never pass between the earth and sun. The term opposition is used to describe the condition when the planet is opposite the sun in the sky as seen from the earth. When a planet is in opposition, it rises when the sun sets and sets when the sun rises. It is in the sky all night long.
Opposition is also when a planet is closest to the earth.
This provides the optimum time to view the planet. Of the brighter planets, Mars was in opposition last February. Jupiter will reach opposition on the first of June. Saturn will be opposite the sun on September 14.
