Every fan of astronomy or science fiction out there likes to have a part of the universe in their own home. No matter if it’s a poster of all the constellations, a prop from the newest movie or a model of the solar system, those things are always there to remind you of your passion.
There is one cool gadget available that will bring more immersion to you or your kid’s room, and they’re called star projectors (home planetariums by some people). These are devices capable of projecting everything from the starry skies to planetary bodies and can be either realistic and educational or mood enhancers.
The best star projector out there is the Encalife Atmosphere and should be your first choice if your budget allows it. Still, there are others that serve a different purpose and any one of them could be a more interesting proposition for your own needs.
List of the best star projectors
1. Encalife Atmosphere “Smart” Star Projector
Best “smart controlled” star projector
Dimensions: 10.47 x 7.76 x 3.11 inches | Weight: 1.92 pounds
One of the new entries to our list is the Atmosphere star projector by Encalife and it deservedly earns our top pick. One of the best bits about the “Atmosphere” is it is voice controllable by either Google Assistant or Alexa voice control once setup (which only takes a few minutes to do), allowing you to control just about all the settings just by voice. This alone sets it apart from most other star projectors.
Alternatively, you can install the Smart Life app on your phone (both iOS and Android compatible) and control everything from the palm of your hand. So if you want to change the nebula colors and brightness to one of the available 16.7 million colors from the color wheel on the mobile app, you can. If you want to program and save different combinations of star speeds and nebula speeds and colors, you can do that.
Finally, while the design of the actual unit won’t determine how good or bad it is, it does look modern and it’s compact enough to sit nicely on your bedside table or elsewhere in your room. Allowing you 4 adjustable angles, so you can either project the image on the wall or ceiling.
A sleep timer and an on/off scheduler can also be set via the phone app, which I found to be pretty useful. Overall, the Atmosphere by Encalife deserves its top spot on the list. This will definitely turn your room into a nebula and starry-night filled sky with its rich and bright colors and a plethora of adjustments that you can make via the mobile phone app.
- Speed of the stars and nebula can be independently controlled
- iOS/Android smart app: controllable from your phone
- Can be controlled by Google Assistant and Alexa voice control
- Extremely quiet during use
- Programmable on/off and sleep timer (stays on for up to 12 hours)
- Not real stars and constellations, more a repeating pattern
- Doesn’t have any built-in speaker, so won’t play any music
2. Encalife Ambience Galaxy & Star Projector (With Speaker)
Second best star projector
Dimensions: 6.65 x 6.61 x 5.31 inches | Weight: 1.76 pounds
If you’re looking for a star projector that can also play music via its built-in bluetooth speaker then the Ambience from Encalife could very well be what you’re after. Compact enough that you can set it up practically anywhere around the house and turn your room into a galactic wonderland.
The Ambience star projector comes with 21 adjustable lighting modes. It has 4 primary colors (blue, white, red, and green), and they can be combined together via the remote control to create up to 21 different color modes, giving you plenty of color options, so you never get bored.
With a quick bluetooth setup on your phone or other music device, you can also play any music you want through its built-in speaker. So you can set the mood or relax with music while watching the light show on your ceiling.
- Built-in bluetooth speaker, control the volume and music from your phone
- Remote control included
- Sleep timer can be set up to 4 hours

Just turn off all the lights in your room, and you’ll be amazed at how realistic its projection looks like. For some additional immersion, there’s also a shooting star function that makes shooting stars appear while the night sky rotates. As a bonus, Sega also includes a 17 x 26-inch double-sided poster of the northern and southern hemisphere.
The main selling point of Sega Homestar Original has to be its interchangeable discs. They will allow you to quickly change the Homestars projector image to other astronomy objects like the Solar System, Galaxies, Disappearing Continents, and much more. There are more than 30 discs to choose from, and they are available at a reasonable price.

We all know and love National Geographic for their excellent documentaries, but who would have thought that they’d step into the realm of home star projectors and make a very powerful one in the process. If you’re looking for a ton of features at a reasonable price, you should seriously consider the Astro Planetarium Multimedia for your next gadget.
Firstly, it brings accurate projections of celestial bodies from two different interchangeable discs. They won’t look as colorful or as flashy as those on more mood oriented projectors, but they will help you improve your knowledge about the night sky and all the shiny things that it holds, making you feel warm inside while you’re gazing at them.
There’s also a built-in FM radio and a 3.5mm AUX connector, so you could find the right relaxing music while you’re enjoying the projections on your ceiling or your wall.

If you need a very compact and reasonably priced star projector, then the BlissLights Sky Lite will be a very good option for you. Thanks to its miniature size, you will be able to place it just about anywhere in your room, and it will also look fairly inconspicuous on your shelf or table thanks to its clean and stylish design.
This particular device projects a blue nebula cloud with rotating multi-colored stars and is powerful enough to cover your entire wall with its nebula effect and the rest of the room with all the small start points. It provides a very soothing experience and any space you put it in will instantly come to life.
It’s also easy to use and set up thanks to its simple control scheme and offers brightness adjustment and the necessary controls to start and stop the rotating motion. You will also have the option to enable only the star or the nebula effect if for some reason you don’t want the projector to display them at the same time.

It’s powered by standard AAA batteries so that you can take it anywhere with you. We do advise you to purchase rechargeable ones to make your life a little easier. The device itself can project high-resolution images of everything from the night sky to different planets, moons, nebulae, and more. The night sky also rotates for even more immersion.
There’s also a built-in timer and auto power-off feature to help you keep those batteries lasting longer while you’re asleep or away from home.

Star, Planet, and Galaxy Projector Buying guide
What to look for when buying a star projector
Can additional discs be purchased?
Depending on the type of star projector, some of them may offer user interchangeable discs. These are used to expand the range of celestial objects that the projectors can display and can either come bundled or available as a separate purchase.
All of them can display the starry skies by themselves, but the additional discs will also allow them to project the Earth, Sun, the Moon, different planets, cosmos, auroras, galaxies and nebulae. These are the most flexible star projectors out there.
How bright is the display
This isn’t the easiest thing to figure out when looking at the product specifications since not all manufacturers are upfront about how bright their star projectors are. Your safest bet is to look at the online reviews before making your purchasing decision.
If there isn’t a good enough review available for the projector you’re interested in, you should build your expectations around its type and price. Cheaper ones, especially those targeted at younger audiences usually don’t offer very bright displays, and the same can be said for those that don’t go for realism and are just meant to change your room’s mood.
Mains powered or battery
Some star projectors can only be powered by plugging them directly into the mains socket, some only on AAA batteries and some on both. There are also ones that can be powered via USB and can be plugged into the mains socket as well as external battery banks or any kind of USB 2.0 or 3.0 port on your PC.
Can a timer be set?
This function is shared between almost all star projectors out there, no matter their type and price point. It simply allows you to decide how long the projector will work before powering off, which makes sense because you wouldn’t want it to work and waste power while you’re asleep or during the day.
Real adult astronomy guide or kids light show
As we’ve mentioned before, there are many different types of star projectors. The most affordable ones usually come in two varieties, accurate ones meant for kids or those that only imitate stars and space phenomena around them just to give your room a new look.
Either of those will still keep you or the kids entertained, but there is always the manual way of sticking the stars to the wall and ceiling to keep the kids occupied.
The real adult star projectors meant to serve as astronomy guides are usually the more expensive ones and tend to offer brighter, sharper, and more detailed projections. They can also offer additional discs to expand their functionality, as well as more options when it comes to fine tuning their projections.
