168. When is the planet Mars not visible to us?
Mars is not visible when at conjunction because its position aligns with the Sun, rendering it lost in the Sun's glare. Opposition and quadrature provide favorable viewing conditions, as does an elongation angle near 180. Conjunction, with its near alignment with the Sun, prevents visibility.
