Best star projectors in 2021: Indoor views to the night sky

Imagine if the night sky could be brought inside. Star projectors are capable of bringing the night sky inside, by filling ceilings and walls with stars and constellations to create an immersive experience that will spark the imagination. Star projectors are easy to use and set up and come in many sizes.

Here are some quick tips to help you choose the right star projector

1. You can find a simulation that corresponds to the actual day and time.

2. The stars will appear sharper if the space is smaller.

3. You can check how many disks are included with each product.

4. If you are using the night light, choose automatic shut-off.

Star projectors are just like everything else. You get what you pay. The more expensive models tend to focus on ambient projections that are room-filling and colorful, but mostly novelty-style. This is because they can project the objects you might see in the night sky. However, the more you spend, the more accurate you will get, and the closer you will get to a science-based, planetarium-style experience. The latter is better suited for children who have a keen interest and knowledge about the night sky. has scoured the market to find the best light projector for room. We’ve gathered the top for creating stars and planets.

There are many reasons to buy

+As realistic as it gets+Lots and lots of upgrade disks

Avoidable reasons

-Expensive-No lens cover

The sleekest and most powerful star projectors on the market, the Sega Toys Homestar Flux satin black is a great value for money. The Homestar Flux is more of a star projector than a planetarium. Its multilevel glass lenses create stunningly atmospheric and precise projections that are bright and sharp. You can adjust the focus to see 60,000 stars. This is a lot more than you will find on other star projectors.

This globe-like product is a success because of the number of stars displayed and the many science-based upgrades available. The product ships with two disks. One shows a starry sky with over 60,000 stars and the other has constellation labels. It features a “shooting Star” function, and an automatic shut-off after 15 minutes, 30, or 60 minutes.

You can find 30 additional disks at, Sega Toys’ official online shop. The aurora australis and the aurora borealis are the highlights. However, the lower-lights are the annular and total solar Eclipses which are merely shown on top of an image of the Milky Way. It’s not very realistic. It’s not very realistic! The North America nebula was captured by NASA’s Spitzer Space Telescope. Also, NASA’s mission imaged the strange seven-star system Jabbah (officially known as Nu Scorpii or IC 4592). Disks can be purchased that mimic fireworks, night jellyfish, and hot-air balloon festivals.


2. National Geographic Astro Planetarium

Power: 3 x AA batteries

Special Features: FM radio, “Shooting star”, mode

There are many reasons to buy

+Realistic nightsky+FM radio and MP3 hookup

Avoidable reasons

Basic blurring at the edges of the ‘Falling star” mode

The National Geographic Astro Planetarium indoor planetarium offers a high-quality, accurate representation of the night skies at a reasonable price. It also comes with many extras. There are two projection disks included. One shows 8,000 stars, the other overlays guidelines to the major constellations. Importantly, you can see what you have set to at the exact time and date you want.

It is very easy to use. It’s easy to adjust the focus wheel and rotate the image in darkness by using the buttons that glow blue. This results in a bright, sharp projection on the ceiling. The optics used in this planetarium come from German optics manufacturer Bresser. They make binoculars and telescopes as well as microscopes. The projection’s edge can be a little blurry due to stars.

An optional “falling-star” mode is a novel feature that projects a flashing meteor every forty seconds but always in the same spot. It’s a unique feature that has nothing to do with astronomy, but it makes this stand out.

The box contains four posters and three AA batteries. It also includes a 3.5mm jack cable that can be used to connect a smartphone or other audio device. You can also listen to music as you stargaze indoors using the FM radio.


3. Bresser Junior Astro-Planetarium Deluxe


Projects start at 2 meters and automatically shuts down



Dimensions: 155x155x191 mm

Weight: 1.4 lbs.

Maximum. Maximum projection size: 160×210 cm

Accuracy: True time and date

Power: 3 x AA batteries

Special features: Auto shutdown, “Falling stars”, mode

There are many reasons to buy

+Realistic night sky+Automatic shut down

Avoidable reasons

Basic-Blurry at the edges, -Shooting Star” mode

The Bresser Junior Astro-Planetarium Deluxe, although not as striking as the Bresser-made National Geographic Astro Planetarium is, is almost identical. This incarnation is available in silver or black and has the same projections and specifications. It also works the same way. However, there are some differences.

You get the same Astro Planetarium Multimedia disks, one with a starry night sky overlay and another that has constellation overlays. It’s all 100% accurate to the day and time you use it.

It can be used to project up to 2 meters. The built-in motors allow you to rotate the image 360o. You can also adjust the image with a focus wheel that revolves around the Bresser lens. You can set it to automatically shut down after 30-60, 60, or 120 minutes. This is helpful if the device is intended for children’s bedrooms and they wish to sleep under the stars.

You can also activate the falling star mode to project a flashing meteor every forty seconds.

The only thing that sets the Bresser Junior Astroplanetarium Deluxe apart from the National Geographic Astro Planetarium, is the absence of an integrated FM radio and the ability to attach an additional audio device. This is a useful difference, but it’s not necessary. The Bresser Junior Astro-Planetarium Deluxe can be purchased at a much lower price.


4. Omegon Star Theater Pro Planetarium



Features 10,000 stars and stunning night-sky “views”,



Dimensions: 150x150x180 mm

Weight: 1.1 lbs.

Maximum. Maximum projection size: Maximum 7.5 m

Accuracy: Random star projects

USB cable for power

Special features: Sun/Earth/Moon projection disk

There are many reasons to buy

+Includes 10,000 stars+Quiet motor

Avoidable reasons

-Fixed speed of rotation -Lacks brightness

This star projector is a serious astronomical instrument that is not as common as other star projectors. The Omegon Star Theater Pro Planetarium ships on a small tripod stand. It is powered by a USB cable, so it can be connected to a portable source of power for special occasions, such as when you need it to be placed in the middle of a room.

Although the adjustable projection distance of 15 cm to 6.8 m is convenient, it does not illuminate the ceiling with 10,000 stars. It lacks brightness, sharpness, and accuracy. You can’t change the time of day so you get a random starry sky without labels, context, or constellation guides. Although it includes the arc of the Milky Way, it is difficult to identify any objects.

It’s a great way to see the night sky, but it is not a very effective learning tool.

The “space night lamp” boasts a multitude of additional disks. The box contains an Earth/Moon/Sun disc, but online you can find more options, including a detailed Milky Way, a star-forming Nebula, the planets in the solar system from a flyover perspective, the Pinwheel Galaxy, and conceptual art of all things.

So that you can also play discs for similar Uncle Milton products, the Omegon Star Theater Pro Planetarium can also be sold under the Uncle Milton brand.

This star projector, like most others, has a handy sleep timer function. It switches off the star projector after 30-60 or 120 minutes.

The default planetarium slide can also be used as a background for images from three slides within the box. Here are 24 images that show objects such as the sun, Earth, and moon as well as the International Space Station and the Space Shuttle. Also, an astronaut is on a spacewalk and has deep-sky sights like galaxies or nebulas. You will also find a poster.

This planetarium mode is best suited for children than adults. It only shows the stars in the northern hemisphere, and it lacks constellation guidelines or labels. So whether or not you can learn anything from the projections is a question.

The Smithsonian Optics Room Planetarium is available in black or blue and can be powered by four AAA batteries. It also has a 15-minute auto-shutoff feature so that children can fall asleep beneath the stars. It’s suitable for young children who are interested in space but not in detail. It is very easy to use and extremely affordable, so it will be a good choice for anyone with low expectations.

-No scientifically valid-Novelty item

Imagine yourself floating through a nebula or in a star cluster. You can’t get scientific accuracy from the BlissLights Sky Lite 2. It is a captivating ambient experience that surpasses its scientific rigor in terms of creativity.

This laser-powered projector is ideal for use in home offices, bedrooms, bathrooms, spas, and other areas. The projector uses an LED and direct laser diode to create dynamic RGB projections. The setup is simple, as the product has three ridges in its bottom that allow it to project at different angles. This includes upwards onto a ceiling. The USB power cable allows for easy positioning. This means that the Sky Lite 2.0 can either be powered from a laptop or a portable battery.

The latest version 2.0 also features the BlissLights app for smartphones. This allows users to connect via Bluetooth and choose from seven effects modes. They can also customize the intensity, brightness, and rotation speed of the projector. You can also create custom colors with the app. Stars are always either green (if purchased the “Classic Green Stars”) or blue (if bought the “Cobalt Blue Stars”)

Sky Lite 2.0 can be described as a lava lamp, although it is impressively different. If you’re looking for a hypnotic journey through a fictional nebula, or is it aurora? If this is what you are looking for, the star projector will deliver.


7. Create A Night Sky Projection Kit


Science-based accuracy and great for kids



Dimensions: 215x170x600 mm

Weight: 0.39 lbs.

Maximum projection size:

Accuracy: Generic constellations available for both hemispheres

Power: 4 x AA batteries

No special features

There are many reasons to buy

+Scientifically accurate+An excellent device

Avoidable reasons

-Back-to-front printed constellations-Blurry projection

This cardboard cut-out is sold in the U.K. under the Science Museum Create A Night Sky, and elsewhere as a 4M Night Sky Projection Kit. It might not appear at first that this would be a worthwhile addition to our list. This is just a small cardboard cut-out that’s placed over a lamp. Although the result is quite simple, it’s what you do to get there that’s clever.

This is a wonderful learning tool. It is a projector-like globe that can be projected onto the night sky. This will allow children to learn about the northern and south hemispheres before they even reach the stars. They will then need to make holes for the major constellations and stars.

The hardware is also very simple. The lamp comes with a square base and requires 4xAA batteries. These are not included. The support is fixed at each corner. Next, place the night sky domes above the lamp. With the lights off, the stars will be projected onto the ceiling and walls. There are some drawbacks. The printed constellations and stars are projected back to front to provide a clear projection. Although it is time-consuming and tedious, this makes for a cost-effective and affordable learning tool. You can expect a novelty nightlight for your child’s bedroom, but nothing more.
