Mars Opposition

A planet is said to be in opposition when Earth lies directly between it and the Sun. As the planet sits in the opposite part of the sky to the Sun, it’s positioned closest to Earth for its current apparition (period of visibility). On this date, Mars will appear larger than usual, making it an optimal time for observation. This phenomenon only occurs every 2 years and 2 months (or to be precise, every 779.94 days).
