What’s a Planetarium?

It’s a place hosting a large room with a dome-shaped ceiling where you can go to see what the skies look like with stars, planets, constellations, galaxies and other galactic objects. A special projector is used to project galaxy images on this dome shaped ceiling. A home planetarium is when you use galaxy projectors to bring all this awesomeness right inside your home.

A Short History of Planetariums

The earliest device that might be considered a planetarium, in the sense that it encircled a space for viewing an artificial sky was a tent with holes that was made by Arab craftsmen. This tent ended up in Europe as a crusade spoils where the emperor Friedrick II of Hohenstaufen took hold of it. 

It’s said that the sky viewers sat within it and a kind of a turntable spun the tent, the holes in the tent represented the stars. Therefore the sky and the constellation motions could be viewed during the day.

Some other sources consider that the Greek Archimedes is the genius creator of the first primitive device able to preview the moves of the Sun, Moon, and other planets. Ans this would be an archaic ancestor of today’s planetarium.


Fast forward 600 hundred years later, this idea led to the creation of several globes and domes for stars viewing. And inspired the creation of  solar system mechanical models that could be driven like the hands of a clock. 

A further development took place in 1900 when a German scholar, Oskar von Miller tried to create an astronomy section inside the museum of Munich, that would celebrate humanity's science and technology accomplishments. 

His idea was to create a planetarium, with a realistic night image of the sky and movement of the stars. Thus, he requested an optical company called Carl Zeiss to implement the idea. But its  execution was more than complex. 


After years of research, they came up with a genius hint: a fixed dome adorned with a projection screen where they would throw various images of sky objects. And in 1924 in Munich, the first planetarium saw the light of the day. Six years later the Zeiss planetarium was launched in North America.

Today, you don’t need to travel to North America or any other country with a planetarium to be able to see the galactic skies. You can bring your own planetarium projector home and enjoy the skies right in the comfort of your own space.



What’s the Best Home Planetarium Projector?

Here is a buyer guide to help you identify a home planetarium that offers the best value for your money.

A Home Planetarium Buyer’s Guide

These devices bring the grandiose night skies inside your walls or ceilings, creating that serene feeling, as if you were watching the real night skies, only without the bugs and the cold associated. 

So, whether you’re looking to buy the best home planetarium for your kids or for yourself, here are some things to consider when choosing the one that best suits your needs:

a.      The Quality of Images and Brightness

One of the most important features to look at is the wattage of the projector. The higher the wattage of the projector, the more bright and crisp the images get. The best home planetarium projector must have a 5-watt; this can still work well if the room has some ambient lighting. Lesser watts such as 3-watt will require your room to be completely dark in order to enjoy the full effects.

The quality of the images is also very important. Do those stars look real or are they blurred? You can consider checking out other customer reviews to see what they say about the quality of the images before you purchase.

b.     Power Source

This is also pretty important to consider when buying your home planetarium projector

For instance, if you intend to keep it in a fixed place within your house, then you should get one with an AC adapter to ensure your view will not be cut short. 

On the other hand if your plans are to use it outdoors e.g. during camping, consider getting one that runs on batteries. Only ensure to have them charged. You will notice that the batteries are about to end when the intensity of the light starts to go down.

c.      Light Source

It is different from the power source; this is about the LED lights or the laser lights. The best home planetariums use the LED lights. When the lens used is of high quality and the images are HD, then you’re guaranteed to get the highest quality images on your walls. The other reason why LED lights are the best is because they last longer and therefore maximizing the value you get for your money.

d.     The Number of Stars

60,000 stars' original home planetariums will completely transform your ceiling. Anything less will not offer the desired effect and will not have the capacity to generate the celestial universe feel. However, with this said, you can still get quality 10,000 stars for the kids and these home planetariums come at a cheaper price.

e.      Adjustable Heights and Angles

Look out for a home planetarium that is adjustable to various ceiling heights. The advantage of this is that you can use it on any kind of ceiling. Another feature is the projection. Ensure it’s adjustable to enable you to set the objects just how you want them, whether on a wall, ceiling or right above your head. You should be able to get the most out of it.

f.       Discs

A good home planetarium provides you with at least two discs to give you the possibility of choosing  different visuals rather than staring at the same shapes and images every night. Tonight you might want to sit under the Andromeda, the other night you just might feel like staring at the southern hemisphere. It’s better to have several  options at your disposal.

g.     The Design Matters

The truth is a home planetarium is a chic and interesting add-on to the interior décor of your room. Besides the lights show it offers, there is still much more it can do during the light day. You want one that offers both high quality functionality and suggests a glimpse of your décor style. This is why home planetarium projectors come in different shapes and sizes. Ones look like simple cute toys, while others look sophisticated and futuristic as if they just landed out of space. Pick your fit.

h.     Extra Features

Timer - It would be great to get one with a timer, as it would make it easier for you when you want to turn it off after a while. E.g. a sure interval after which you consider will have fallen asleep.

Rotation - this is great especially for helping kids to sleep; some will even let you pick the rotation speed.

Special effects - it would be nice if your home planetarium offered special effects such as shooting stars, any twinkling effects and so forth. This would be a sight to behold even for adults.

Bonus Tips on How to Use Your Home Planetarium

To get the best out of your home planetarium is really simple because there aren’t too many conditions to consider. However, the golden rule of using home planetariums that applies across all devices and models is that the room where you’re using it must be completely dark. This is obvious to avoid losing any atmosphere; it helps capture everything including the smallest details.

Another simple tip is to ensure that you set your device in an even manner in order to get an optimal image on your wall or ceiling.

And finally, for the devices that require batteries or charging, for best results, ensure that they have full power. If not you may get blurry images and you may also lose out on some details.


What is the Difference Between a Home Planetarium and a Star Projector?

Most people cannot tell the difference between a star projector and a home planetarium, but these are different devices with very different functions.


            The Function and Usage

    Star projectors are very simplistic in nature and are mainly made for entertainment, their main job is to simply throw twinkly colorful stars on the wall or the ceiling e.g. at a party. The home planetarium on the other hand is designed to help users discover more about the skies, the nebula, planets, the galaxies and everything cosmic.

                The Pricing

    You can use the pricing to tell the difference, star projectors are simply cheaper while home planetariums have a higher price tag.



    We all need some space and now more than ever, these best home planetarium projectors will not only show you clear skies, they will also help you clear your mind. As such, let your kids or yourself widen the eyes and get lost into space.
