Constellations visible from the UK

Last updated 4 November 2026

From the UK you can see most of the 88 official constellations, in whole or in part, over the course of a year, because about four-fifths of the whole sky rises above the British horizon at some point. A handful around the North Star, including Ursa Major (with the Plough), Ursa Minor and Cassiopeia, are up on every clear night. The rest come and go with the seasons: Orion leads the winter, Leo the spring, the Summer Triangle the summer and Pegasus the autumn.

Up every night: the circumpolar constellations

Because the UK is well north of the equator, the sky around the North Star never sets. These circumpolar constellations are there on every clear night, though where they sit changes with the season and the hour:

• Ursa Major, the Great Bear, containing the Plough: high overhead on spring evenings, low in the north on autumn evenings. See our guide to the Plough.
• Ursa Minor, the Little Bear, with Polaris at the end of its tail. See how to find the North Star.
• Cassiopeia, a bright W or M on the opposite side of Polaris from the Plough.
• Cepheus, a faint house shape beside Cassiopeia.
• Draco, the Dragon, a long, faint line of stars winding between the two Bears.

From most of the UK, parts of Perseus, Auriga, Cygnus and Lyra never set either, which is why bright Capella, Deneb and (from most places) Vega are always somewhere above the horizon.

Season by season

This is the mid-evening view, roughly two to three hours after dark. Later at night the next season's stars are already rising in the east.

Winter and summer have guides of their own, winter constellations and summer constellations, and Orion has a dedicated guide. Spring and autumn in brief:

Spring: Leo and Boötes. Leo is one of the few constellations that looks like its name. A backwards question mark of stars, the Sickle, forms the lion's head and mane, with bright Regulus at its foot, and a triangle of stars to the east makes the hindquarters. For Boötes, follow the curve of the Plough's handle away from the bowl to orange Arcturus, the brightest star of the spring sky.

Autumn: Pegasus and Andromeda. The Great Square of Pegasus is a large, fairly empty box of four stars high in the south on autumn evenings; the star at its top-left corner actually belongs to Andromeda. From there a chain of stars leads to the Andromeda Galaxy, a misty oval visible to the naked eye from dark sites and about 2.5 million light years away, the most distant thing most people will ever see without a telescope.

Why the sky changes through the year

Two motions are at work. Each night the Earth's rotation makes the whole sky wheel around the North Star from east to west, so stars rise and set like the Sun. Over the year, the Earth's orbit means we face a different direction into space at night, so the evening constellations slowly shift: each one rises about four minutes earlier every night, which adds up to two hours a month. That is why Orion rules winter evenings but is lost in the Sun's glare in summer, and why early risers can preview the next season: Orion is already rising in the east in the small hours of late summer.

What a constellation is

A constellation is an officially defined area of the sky, not just a dot-to-dot picture. The International Astronomical Union (IAU) adopted a list of 88 in 1922, and the Belgian astronomer Eugène Delporte drew their precise boundaries, published in 1930. Every star in the sky falls inside exactly one of them.

Many names are ancient, handed down from Greek and earlier Babylonian sky-lore; others, mostly in the southern sky, were added by European navigators and astronomers from the 1500s onwards. Smaller, unofficial patterns inside constellations are asterisms. The best known is the Plough, seven stars within the much larger Ursa Major.

Southern constellations

Only partly. Constellations far south of the celestial equator, such as Crux (the Southern Cross), Centaurus and Carina, never rise from Britain. Scorpius and Sagittarius are on the edge: their northern parts creep above the southern horizon on summer nights, but the whole figures are best seen from the Mediterranean or further south.

Learning them, one at a time

1. Start with the Plough. It is up every night from the UK and points to the North Star, Arcturus and Leo.
2. Add one pattern a month. Hop from a constellation you know to its neighbour rather than trying to learn the whole sky at once.
3. Measure with your hand. At arm's length your fist covers about ten degrees of sky. The Plough is roughly two and a half fists long.
4. Let your eyes adapt. Fainter stars appear after 20 to 30 minutes away from bright lights, and a red torch keeps your night vision.
5. Mind the Moon. Moonlight washes out the fainter stars, so the week around new Moon is best for learning; our full Moon calendar helps you plan.
