Best Star Projector (Home Planetarium Right On Your Ceiling)

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 Sega Homestar Original 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.

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.

Quick Recap Of The Best Star Projectors

Conclusion

So, if you’ve ever dreamed about having the space itself in your own room or you’re fascinated about its colors and different celestial bodies, or you want your kids to upgrade their knowledge in a more fun and visual way, star projectors will surely help you achieve those goals.

The Sega Homestar Original is the most impressive star projector out there because of its great image quality and the impressive number of exchangeable discs it’s capable of displaying. It’s still not ideal if kids or atmosphere are your priority due to its high price point and thus, other star projectors in our article may serve you better without hitting your budget too hard.
