<\/a>The views of Saturn change over the years, since the axis of the planet (and thus also the ring system in its equatorial plane) are fixed in space \u2013 exactly like the Earth\u2018s axis always points at the north star, Saturn and its rings are aligned to their own north star. Since the Earth and Saturn revolve at different speeds around the Sun, the Earth is sometimes above or below the plane of the rings and sometimes exactly in the same plane. If we are looking exactly at the edge of the ring system, they seem to disappear, as it is less than 6 miles (10 km) thick. Only very large telescopes might see the ring system at this time. Since the ring system contributes much to the brightness of the planet, Saturn will also appear darker in the sky. Conversely, Saturn and its rings are very striking when the Earth is far above or below the ring plane. Approximately every 15 years the Earth passes through the plane of the rings, including the years 2009 and 2025. In 1995, the annular passage coincided with Saturn\u2019s opposition, and because of the complicated path of the planet in the sky (when we overtake it, it seems to move backwards for some time) the planetary ring system disappeared three times in succession \u2013 a rare spectacle.<\/p>\n
