Star projectors can be wondrous to behold, turning a room into a starry display, awash with colors, nebulas and more. But as impressive as they are in action, you needn't spend a fortune. We've rounded up the best star projectors under $100, some less than $20.
It's important, however, to distinguish between ambient mood projectors and accurate projectors. As gorgeous as the former can look in action, they don't mirror the real night sky. Some star projectors, on the other hand, project accurate images of planets, stars and other bodies. In our guide, we highlight which is which to help you make the right choice.
Our expert reviewers have put every one of these projectors to the test so you can be sure you're getting your money's worth. Or if budget is less of an issue, take a look at our wider round-up of the best star projectors.

✅You have limited space: Though powerful, the Piko Galaxy Projector is small enough to sit on a shelf.
❌You want scientific accuracy: This model doesn't use accurate star maps and is for ambience only.
❌You want a rechargeable projector: Unlike some other models on this list, this has to be plugged into a power supply to operate.
🔎 The Pikoy Galaxy Projector offers excellent value and though we'd prefer it were rechargeable it's a good gift for a child or adult. ★★★½
When we reviewed the Pikoy Galaxy Projector, it was available for less than $20 and while the price has since gone up it's still fantastic value at less than $30.
It's a surprisingly small projector, capable of sitting neatly in your palm. Despite its size, it's not rechargeable but it's compact enough to perch on a shelf and powerful enough to fill a small to mid-sized room with colorful lights and lasers. While adults will enjoy this display, it's geared towards children, coming in white, navy, blue and pale pink colors.
One child-friendly feature, in particular, is the built-in speaker that can be used to play children to sleep with audiobooks, nursery rhymes, rainforest sounds and more. And thanks to the backlit buttons, you can switch it off in the dark without the risk of waking its owner.

✅ You want customisable projections: The BlissLights Sky Light Evolve's displays look gorgeous in action, and you can tweak them to your heart's content.
❌ You want scientific accuracy: As gorgeous as it looks in motion, the projections do not accurately represent the night sky.
❌ You want a rechargeable projector: This model doesn't run on batteries and has to remain plugged in to operate.
🔎 The BlissLights Sky Lite Evolve's display may not be scientifically accurate, but it's certainly impressive. The nebulas are bright and endearing, complimented perfectly by the hue of the blue/green lasers, and the colour shifts are seamlessly blended. ★★★½
Pick up the BlissLights Sky Lite Evolve and you'll be immediately struck by its spherical shape. Its round design means it has near 360-degree projection; just place it in the middle of the room and you'll be treated to its undeniably gorgeous display.
You can choose between three models: blue, green and no stars, the latter of which is a little cheaper. All feature colour blending technology which ensures its shifting transitions are never jarring.
You can happily sit back and let the BlissLights Sky Lite Evolve operate, not least because it's so silent. But it's also supremely customisable. It can be integrated into your smart home setup and, via a mobile phone app, you can edit the already impressive light shows.
In our BlissLights Sky Lite Evolve review we awarded it four and a half stars and it's hard to beat a powerful but pocket-friendly star projector. Unless you need scientific accuracy, this is a worthy purchase.

✅ You want an educational projector: The Deep Space Home Planetarium projects NASA images of spacecraft, astronauts, nebulae and planets.
✅ Your children are into space: This projector is a STEM tool, aimed firmly at young children and they should have little problem using it.
❌ You want a shifting, room-filling stellar display: As accurate as the images it projects are, they're aimed at education, not ambience.
🔎 The Brainstorm Toys Deep Space Home Planetarium is a STEM toy that'll entertain and educate. Kids between 6 and 10 will love going hands-on with it and sharing their knowledge with others. ★★★½
It's likely a coincidence but the Brainstorm Toys Deep Space Home Planetarium's resemblance to R2D2 is sure to get the attention of adults and children alike. It's marketed firmly at the latter, a STEM tool designed to educate and entertain children from 6 upwards, who have a burgeoning interest in space.
It comes with changeable (rotating) discs showing 24 official NASA images of nebulae, spacecraft, astronauts, planets and the moon, some taken by the Hubble Space Telescope. It's not aimed at creating an ambience, rather, it's a tool for teaching children about the night sky.
The Deep Space Home Planetarium is ideal for children ages 6 and up. It requires hands-on operation, which is sure to keep children engaged with it longer. You can't currently buy more discs, but we still think this is a fantastic, bargain-priced investment for space-loving children.

✅ You want an educational projector: The Dark Skys Skyview Pocket Planetarium offers an accurate view of the Northern Hemisphere's constellations.
✅ You want portability: This rechargeable projector is small enough that you can slip it into a pocket.
❌ You want a mood projector: You can't alter this projector's colors and there's no sleep timer.
❌ You want a selection of views: You're limited to the one view of the Northern Hemisphere.
🔎 The Dark Skys Skyview Pocket Planetarium is a portable educational tool that teach children about the Northern Hemisphere's constellations. ★★★½
If you're looking for an educational projector that you can slip in your pocket, the Dark Skys Skyview Pocket Planetarium fits the bill. Not only does it project accurate images of the Northern Hemisphere's skies, but it also has an optional line overlay, making it easier to pick out each constellation. We think it's the best pocketable projector for kids.
You can use it to spot Ursa Major, Ursa Minor, Cygnus, Draco and others, all revolving around Polaris, and it also boasts a rechargeable battery, making it extra portable. It doesn't boast a lot in the way of functionality, and it does require a darkened room, more so than some other projectors which operate well in lit rooms.
But for less than $50 it's a great way to introduce children to the cosmos and, if you're in the Northern Hemisphere, you can head outside and see if you can spot those same stars you've been looking at moments earlier.

The Encalife Ambience Galaxy and Star Projector lives up to its name, enhancing the ambience of any room with its vivid displays. It provides four colors (blue, green, white and red) and offers plenty of customisation options and, thanks to its dome design, it can project its display to fill a whole room.
In our Encalife Ambience Galaxy and Star Projector review, we were impressed by its build quality (even if its packaging is lackluster) and by how quietly it operated. Its sleek design and black colour mean it blends in with many home entertainment systems.
Thanks to its Bluetooth speaker, you can couple its already impressive displays with music, turning a room into a starry disco or a meditation haven. It's not scientifically accurate, but it projects a fantastic light show, ideal for adults or children.

Best star projectors under $100 FAQs
What's the difference between ambient projectors and accurate projectors?
Many star projectors are ambient projectors, meaning they project beautiful, shifting images of nebulae, stars and more. These are excellent for altering the mood in a room, whether you're trying to lull a child to sleep or want to relax. Many ambient projectors let you customise this display, changing the colours, altering the speed and more.
However, if you go outside, you won't be able to spot those exact stars because these projectors aren't scientifically accurate. Ambient projectors offer a more general and impressive representation of the cosmos.
Scientifically accurate projectors, on the other hand, project images of the actual night sky or, at least, a snapshot of it. Some use slides to project NASA imagery of nebulae and planets, an accurate representation of those objects. On the whole, however, they're less customisable. The latter are better for education, while the former are suitable for relaxation or meditation.
How do I tell if a projector is accurate or ambient?
In our guide, you'll find a table beneath each projector's entry that explains whether a projector is accurate or not. If you're looking online, if a projector doesn't specifically mention it's scientifically accurate, chances are it's not. The cheaper a projector is, the less likely it is to be accurate.
Should I spend more than $100 on a star projector?
All these star projectors come in at under the $100 mark, but should you spend more? If you're after an ambient, mood-setting projector, the answer is essentially no. Whether it's for relaxation or a child's room, the ambient projectors we've highlighted are excellent buys.
If, on the other hand, you're after a scientifically accurate projector, there are benefits to spending more. The Sega Homestar Flux is priced at over $250 but it really does create amazing, accurate recreations of the night sky.
In our review of the Sega Homestar Flux, we remarked that it "It’s pricer than other home planetariums, but it does feel like you get what you pay for." That extra $150 is quite an ask, however.
How we test
Each star projector is tested by either our expert staff or knowledgeable freelance contributors who know their subject areas in depth. This ensures fair reviewing is backed by personal, hands-on experience with each star projector and is judged based on its price point, class and intended use. For example, comparing a top-of-the-range star projector from one of the largest producers of star projectors to a make-your-own kit made from cardboard wouldn't be appropriate, though each star projector might be the best-performing product in its own class, and that is how we've categorized them in this guide.
