A conjunction is commonly thought to occur when two or more celestial objects (planets, stars, the moon, etc.) move into close proximity to each other. Technically speaking, a conjunction occurs when two or more celestial objects have the same line of longitude in the sky. Nevertheless, because all planets orbit the Sun in the same approximate plane, when planets conjoin they are typically seen closely together.
