The Moon and Saturn will make a ‘close approach’ this evening, reaching at an angular distance from each other across the night sky of just 3°58′. The Moon – which, seven days old, will appear in its first quarter – will be at a magnitude, or brightness, of -12.1 and Saturn will be at magnitude 0.4. Unfortunately, the moment of greatest apparent closeness will occur at around 11.25pm – at which point, both will likely be obscured given proximity to the horizon. However, good views of the close approach should be achievable, weather permitting, at around 9.15pm.Viewed from the UK, both the Moon and Saturn will be visible in the evening sky from around 4.55pm onwards above the horizon towards the southeast.They will reach their highest point in the sky – at about 21 degrees above the horizon – at about 6.41pm.They will remain in view until around 10.11pm, when they will sink below 7° above the south-western horizon, and likely end up obscured from view.During the approach, both the Moon and Saturn will appear in the constellation of Capricornus.
