4 October

Saturn at opposition

Saturn reaches opposition on 4 October — directly opposite the Sun, so it rises at sunset, sets at sunrise and is at its biggest and brightest of the year. The best night to catch the rings through even a small telescope.

26 September · lesser-known

Neptune at opposition

The most distant planet reaches opposition on 26 September — its brightest for the year, though still faint. A rewarding challenge target: Neptune shows as a tiny blue-grey disc through a telescope. One for the keen.
