When a full Moon makes its closest pass to Earth in its orbit it appears up to 14 percent bigger and 30 percent brighter than average, making it a supermoon. This month’s full Moon on Monday 14 November is the closest Moon to Earth since 26 January 1948. The Moon won’t be this super again until 25 November 2034!
The penultimate 2016 occultation of Neptune by the Moon occurs on 9 November for observers in Western Asia, Eastern Europe and northernmost Africa. In Western Europe, the nine-day-old waxing gibbous Moon merely brushes by the outermost planet, but the pair will be close enough to be seen within the same field of view of a typical binocular from the UK.
At 9:24am GMT on 31 October 2016, near-Earth asteroid 164121 (2003 YT1) will safely fly by at a distance of 3.2 million miles (5.2 million kilometres), or 13.5 times the distance of the Moon. Furthermore, this 1.1-mile-(1.7-kilometre)-wide Apollo asteroid also passes very close to Polaris early on 2 November, creating a rare astrophotographic and observing opportunity.
UK observers with a clear sky an hour before sunrise on Friday 28 October should look very low in the east-southeast to see the slim crescent of the 27-day-old Moon less than four lunar diameters away from largest planet Jupiter. The Moon and Jupiter are also joined by third-magnitude double star gamma (γ) Virginis, commonly known as Porrima.
Ceres, the largest minor planet inside the orbit of Neptune, passed closest to Earth on the evening of 22 October — the night of the last quarter Moon. With the lunar crescent now confined to the morning sky, grab your binoculars or telescope, print out some star charts from our online guide and track down the brightest of the dwarf planets while at its best.
Have you ever seen Uranus with the naked eye? If not, moonless nights in October offer ideal conditions to test your visual acuity and sky clarity. Uranus reaches opposition on 15 October and attains a respectable altitude in the southern sky as seen from the British Isles. Here is our guide to tracking down the seventh planet from the Sun.
Mercury is currently putting on a fine show in the east before dawn. Find a UK location with an unobstructed view due east an hour before sunrise to see the innermost planet some 6 degrees above the horizon from about 25 September—5 October. The very old crescent Moon lies just 2 degrees from Mercury at dawn on Thursday, 29 September.
Observers up for an extreme observing challenge may care to make an attempt at viewing the almost full Moon pass in front of planet Neptune soon after 8pm BST on Thursday, 15 September. The planet’s disappearance occurs at a low altitude in twilight for the British Isles, but can also be seen from a large swathe of Europe and western Russia.
