How to Find Polaris: North Star Guide for Beginners
To find Polaris, the North Star, locate the Big Dipper, draw a line through the two stars at the end of its bowl (Merak and Dubhe), and extend that line about five times the gap between them. You will land on Polaris, a moderately bright star that marks true north. If the Big Dipper is low, use the W-shaped constellation Cassiopeia instead.
Polaris is the most useful star in the northern sky for one simple reason: it barely moves. Every other star appears to wheel around it through the night, which makes it a fixed landmark for navigation, for learning the constellations, and for aligning an equatorial telescope mount. This guide is written for stargazers in the United States and the rest of the Northern Hemisphere, and it works for any beginner, with or without a telescope.
What is Polaris, and why is it called the North Star?
Polaris is a star in the constellation Ursa Minor (the Little Bear) that sits within about one degree of the north celestial pole, the point in the sky directly above Earth's north pole. Because Earth's axis points almost straight at it, Polaris stays nearly in the same spot all night and all year while the rest of the sky rotates around it.
Two common myths are worth clearing up. Polaris is not the brightest star in the sky; it is a moderately bright, second-magnitude star (magnitude is the standard scale of star brightness, where smaller numbers are brighter). It is also far away, roughly 430 light-years from Earth, so it looks modest. Its value is its position, not its brilliance.
How do I find Polaris using the Big Dipper?
The Big Dipper method is the classic way to find the North Star: use the two "pointer stars" at the end of the Dipper's bowl to aim straight at Polaris. The Big Dipper is an asterism, meaning a recognizable star pattern that is part of a larger constellation (here, Ursa Major, the Great Bear).
- Face north and find the Big Dipper. Look for seven stars forming a ladle: four in the bowl and three in the curved handle.
- Find the two pointer stars. They are the two stars on the outer edge of the bowl, the side farthest from the handle. Their names are Merak (the lower one) and Dubhe (the upper one).
- Draw an imaginary line from Merak through Dubhe. Keep going in the same direction.
- Measure about five gaps. Extend the line about five times the distance between the two pointers, which is roughly 28 degrees of sky, or about three closed fists held at arm's length.
- Confirm the star. The first moderately bright star you meet in an otherwise empty patch of sky is Polaris. It is also the tip of the Little Dipper's handle.
A quick sizing trick: a closed fist held at arm's length covers about 10 degrees of sky, and the span between the two pointer stars is about half of that. You can check your fist measurement against the printed scale on a star chart.
How do I find Polaris when the Big Dipper is low?
When the Big Dipper is hidden by trees, buildings, or the horizon, switch to Cassiopeia, a W-shaped (or M-shaped) constellation on the opposite side of Polaris. Cassiopeia and the Big Dipper sit on opposite sides of the pole, so when one is low, the other is usually high.
This matters right now. On October evenings from the United States, the Big Dipper hangs low in the northern sky and can sink below the horizon for observers in the southern states, while Cassiopeia climbs high in the northeast. Look for the W, then measure about three fists from its middle star toward the northern horizon; Polaris is the moderately bright star in the sparse patch of sky there.

Which method is best for me?
| Method | Strengths | Watch-outs | Best for |
|---|---|---|---|
| Big Dipper pointers | Fast, needs no tools, easy to remember | Dipper is low on autumn evenings and can be hidden from southern states | Spring and summer evenings, or any time the Dipper is well above the horizon |
| Cassiopeia | High and easy to spot in fall and winter evenings | Less precise than the pointer stars; the W can be faint under city lights | Autumn and winter evenings; a backup when the Dipper is low |
| Planisphere or star chart, such as the Explore Scientific Tirion Planisphere (0-60° North) | Shows exactly where Polaris sits for your date and time; double-sided for different latitude ranges | Must be set to the correct date and time; needs a dim red light to read | Learning the whole northern sky, not just Polaris |
| Phone stargazing app | Points you to Polaris with live compass and GPS | Bright screens ruin night vision; compass can drift near metal or electronics | Quick confirmation once you have a rough idea |
How high is Polaris in the sky where I live?
Polaris appears above the northern horizon at an angle roughly equal to your latitude. This is why the star hugs the horizon in Florida and rides high overhead in Alaska. You can use it to estimate your latitude, or to know where to look.
| U.S. city | Approximate latitude | Polaris height above north horizon |
|---|---|---|
| Miami, Florida | 26° N | about 26° (under three fists) |
| Dallas, Texas | 33° N | about 33° |
| Denver, Colorado | 40° N | about 40° (four fists) |
| Chicago, Illinois | 42° N | about 42° |
| Seattle, Washington | 48° N | about 48° (nearly five fists) |
Polaris is essentially never visible from the Southern Hemisphere. If you are in Hawaii or Puerto Rico, expect it to sit very low, so you need a clear northern horizon.
What gear helps you find and use Polaris?
You do not need any equipment to find Polaris, but three inexpensive items make the experience easier and more enjoyable. All of them are useful on every future observing night, not just this one.
- A planisphere or star chart. A rotating star map shows the whole sky for your date and time. If you are new to charts, our guide on how to use a star chart walks through the steps, and our star maps and astronomy flashlights collection has more options.
- A red light. Red light preserves your dark adaptation (the 20 to 30 minutes your eyes need to become sensitive to faint stars). The Explore Scientific USB Power Bank with Red LED Flashlight pairs a red LED with a USB battery, so it can read your chart and charge a phone on the same night.
- Binoculars. Binoculars show many more stars around Polaris, including the fainter stars of the Little Dipper. A 10x50 pair like the Alpen Apex XP 10x50 ED Waterproof Binoculars magnifies ten times and has 50 mm lenses, a combination covered in our guide to the best binoculars for stargazing.

Why does Polaris matter for telescope users?
Polaris is how you aim an equatorial mount at the sky. An equatorial mount has one axis tilted to match your latitude and pointed at the celestial pole, so that a single slow motion can follow the stars as Earth turns. Pointing that axis at Polaris is called polar alignment, and it is the first step in tracking objects or taking long-exposure photos. If you are choosing between mount types, see our explainer on alt-azimuth vs. equatorial telescope mounts.
Polaris is also a rewarding target in its own right. Through a telescope, it appears as a close pair: the main star plus a much fainter companion that needs a steady sky and a small telescope to separate. Treat it as a bonus object once you have found it.
A 10-minute Polaris practice session
The fastest way to learn the northern sky is to find Polaris, then use it as your anchor to meet the other constellations that circle it. Try this on the next clear evening:
- Let your eyes adapt for 15 to 20 minutes away from bright lights, using only a dim red light.
- Find Polaris using the method that fits the season: Big Dipper in spring and summer, Cassiopeia in fall and winter.
- Hold up your fist to check Polaris against your latitude from the table above.
- Notice how the Dipper or Cassiopeia swings around Polaris if you return an hour later.
- Scan the area with binoculars and try to trace the Little Dipper.
Frequently asked questions
Is Polaris the brightest star in the sky?
No. Polaris is a moderately bright, second-magnitude star, and many stars, including Sirius, Vega, and Arcturus, are brighter. Polaris is famous because it stays almost fixed above the north pole, not because it is the brightest star.
Can you see Polaris from the Southern Hemisphere?
No. Polaris is below the horizon for observers in the Southern Hemisphere, so people there use other methods, such as the Southern Cross, to find south. Polaris is visible only from the Northern Hemisphere.
Does Polaris always point exactly to true north?
Polaris points very close to true north, within about one degree, which is accurate enough for casual navigation and for rough polar alignment. It is not the exact pole, so astrophotographers use a polar scope or alignment app for precision.
What if the Big Dipper is not visible when I look for Polaris?
Use Cassiopeia, the W-shaped constellation on the opposite side of Polaris. On autumn evenings in the United States, Cassiopeia is high in the northeast while the Big Dipper sits low. A planisphere will show you where both patterns are for your date and time.
Do I need a telescope to find the North Star?
No. You can find the North Star with your naked eyes in about a minute once you know the Big Dipper method. Binoculars and a planisphere help you explore the stars around it, but neither is required.
