How to find the North Star, and how high Polaris sits over your city

Face north after dark and find the Big Dipper, or the W of Cassiopeia when the Dipper is low. The two stars at the end of the Dipper's bowl point at Polaris: follow them for about five times the gap between them, and the first star you'd notice (not dazzling, a match for the Dipper's own stars) is the North Star. It stands about as high above the horizon as your latitude, roughly 52 degrees in London, 41 in New York, 34 in Los Angeles and 13 in Bengaluru, and barely moves all night.

Polaris is famous because it sits almost straight above Earth's north pole, so it stays put while the rest of the sky moves. When my Mac app, Orbit, first drew a real sky on 1 October, Polaris was one of the checks in my build log: 34.3 degrees up over Los Angeles, a city at 34.05 degrees north.

How to find Polaris from the Big Dipper

In the UK the Big Dipper is the Plough, and in India it's the Saptarishi, the seven sages. Merak and Dubhe are called the Pointers because that's their whole job.

EarthSky's guide to Polaris gives the five-times rule, and it holds up. In Orbit's star catalogue the Pointers are 5.4 degrees apart and Dubhe is 28.7 degrees from Polaris, so "about five" works out at 5.3. A fist at arm's length covers about 10 degrees, which is where the three fists come from.

How high the Dipper stands depends on the season, and EarthSky's Big Dipper page rates spring evenings best and autumn worst. At 7 PM on 15 November, from London, Dubhe is 23 degrees up and Merak 18, one above the other below Polaris. From New York at 8 PM the same night they're only 13 and 7 degrees up, so a row of trees to the north can hide the whole thing. Wait for spring: at 10 PM in mid-March, Dubhe is 59 degrees up over New York.

A dark night sky over dark hills, with compass letters NW, N and NE along the bottom. High in the middle a star is labelled Polaris, with a faint chain of stars curling down to its left. Low in the north, as part of a larger stick figure, seven stars form a dipper with its handle to the left and its bowl near the centre, the bowl's two right-hand stars one above the other below Polaris. Capella is labelled on the right.

How to find Polaris using Cassiopeia

Cassiopeia is a W of five stars (an M at other hours) on the opposite side of Polaris from the Big Dipper. When one is low the other is high, which makes the W the backup for autumn and winter evenings.

Polaris sits almost exactly halfway between the two patterns: 28.7 degrees from Dubhe and 28.6 from the middle star of the W. So start at that middle star and go the same distance down towards the northern horizon, roughly three fists again, and you're at Polaris.

Is the North Star the brightest star?

No. Astronomers measure brightness in magnitudes, where a smaller number means brighter, and Polaris is about magnitude 2. EarthSky ranks it around the 48th brightest star. Sirius, the brightest of all, is about magnitude minus 1.5, roughly 24 times brighter than Polaris.

Orbit's catalogue puts Polaris 48th of the 2,874 stars it draws. The label rule in my drawing code is magnitude 1.5 or brighter, or a star called Polaris, which doesn't make the cut and gets a label anyway.

In late 2026, if your "North Star" is dazzling and in the east or south-east before sunrise, it's almost certainly a planet, and the bright star in the east before sunrise says which one.

How high is the North Star in the sky?

Due north, at about the same height above the horizon as your latitude, every night of the year. It isn't quite on the pole (0.6 degrees off in November 2026), so through a day it rises and sinks up to 0.6 degrees either side of your latitude, and it never strays more than 1.4 degrees from due north, even from Reykjavík.

Can you see the North Star from India?

In the Puranas the pole star is Dhruva, a name that means fixed (Wikipedia), and you can see it from every part of India, low in the north: about 29 degrees up from Delhi, 19 from Mumbai, 13 from Bengaluru and 8 from Kanyakumari. Stars that low fade in haze, so a clear northern horizon helps most.

The Big Dipper is the tricky part. From Bengaluru at 9 PM it's below the horizon from late August until about New Year, so from September to January the W does the pointing.

A dark night sky over dark hills, with compass letters NW, N and NE. Low above the hills over N, a star is labelled Polaris, with a faint line of stars running down to its left. High above it and slightly right, five stars are joined in a W. Deneb and Vega are labelled on the left and Capella on the right.

Why doesn't the North Star move?

It does move, in a circle too small to notice: 1.25 degrees across each day, about two and a half full Moons wide. That's because Earth's axis points almost straight at it (NASA StarChild). As Earth spins, the whole sky circles that point, and Polaris is only 0.6 degrees from it.

The sky turns at 15 degrees an hour, a quarter of a degree a minute. Face Orbit north and leave it: between one redraw and the next the change is too small to see, but look up three hours later and whatever's near the pole has swung 45 degrees round Polaris.

Even the pole drifts, very slowly. The axis wobbles like a spinning top and goes round once in about 26,000 years, a motion called precession. EarthSky says Polaris comes closest to the pole on 24 March 2100, 0.45 degrees away, and slides off after that. NASA's StarChild puts Thuban, in Draco, as the pole star around 3000 BC, and Vega in about 13,000 years.

Once you can find the pole, Orion is the next one to learn, and both hemispheres get it.

Can you see the North Star from Australia?

No. South of about the equator Polaris stays below the northern horizon, and from Sydney it never comes closer than 33 degrees below it.

The south has no bright pole star. The nearest naked-eye star is Sigma Octantis, about a degree from the pole at magnitude 5.4, barely visible even from a dark site. Orbit draws it, as Polaris Australis, far too faint for a label.

Southerners use the Southern Cross instead. Extend its long arm, from Gacrux at the head through Acrux at the foot, about four and a half times its own length and you reach the south celestial pole, the point in the sky straight above Earth's south pole (Astronomy WA). Drop straight down from there to the horizon and you're facing south. Tried on Orbit's catalogue for November 2026, the rule lands 2.7 degrees from the pole, close enough to walk by.

Pick your season, though. From Sydney at 9 PM on 15 November the Cross is upside down and hugging the southern horizon, while at 9 PM on 15 April 2027 it's high in the south-south-east. Living with a real sky wallpaper shows it over Bengaluru.

Seeing Polaris on your Mac

Orbit: Live Sky Desktop, the Mac app I make, puts the real sky behind your desktop icons and redraws it once a minute. Turned to face north, it shows the Dipper or the W circling Polaris over your city.

North of the equator it faces south at first, so right-click the Moon in the menu bar, set Facing to North and switch on Labels on the Sky. Polaris then shows up by name, as high above the desktop's horizon as it is above yours (from Reykjavík, at 64 degrees, it's just past the top of the view). The constellation lines draw the Dipper and the W, though their stars aren't labelled. Pick one of 13 cities, or Use My Location, which keeps your coordinates on the Mac.
