Works perfectly.
Nice set. We were able to automatically make it run using a motor after we built it, which was very easy to do.

Retailer reviews
Summarized retailer review data when available.
Nice set. We were able to automatically make it run using a motor after we built it, which was very easy to do.
This set has much to offer. It does its job well in showing the timing of movements of the Earth, Sun and Moon. It celebrates gears and mechanisms that are too often hidden behind panels in other sets. It is full of functionality and movement where some other sets are just for static display. It has interesting pieces, especially the spheres and circular beams, so good that I bought 4 sets. More Technic sets like this please! Just for fun, with a second set I converted it to the Tatooine system of twin suns and 3 moons; the planet could do to be tan-coloured but it's all about using the pieces you have.
He enjoyed the gearing and visual of the build. He did wish they had added more planets to the design. He like that it displayed the month and moon phase that was current to today's day and you could change it. He liked the earth was tilted on an angle to make it factual. The turntable below earth and the moon was cleaver.
Excellent!
A really fun set to build with many "aha!" moments due to the complex gear mechanism. And once it's finished, the moon and Earth also align realistically.
Very fun and educational product! It's great to be able to explain the concepts of day and night, months, years, and eclipses in this way to children! However, be careful when attaching the moon cycle stickers. The instructions and the image on the box seem to assume moon illumination as seen from the Southern Hemisphere, so the first quarter should be illuminated with the left side of the moon. However, on the Northern Hemisphere (and therefore in the Netherlands), this is "upside down", so the first quarter should be illuminated with the right side of the moon. To solve this, the moon stickers unfortunately need to be cut into individual pieces so they can be attached correctly.
A very nice combination of history, science, and technology. Educational and beautiful to see on display. A very fun set. I would like to see more sets that are scientifically oriented.
Top product, very educational, very detailed, lots of moving parts... lots of fun! Really one of the best LEGO sets made in years.
My son received this set from his auntie and when nearly finished he realised that planet earth had two northern parts 6463209 and not a northern 6463209 and southern part 6463208. Call Customer services and they told me the part was out of stock. I asked to be put on a waiting list which Lego can't do. they even suggested to try and order it from a third party. Now we are just in a limbo and were told to try and come back once in a while and try again .... Not what I expected. Kind regards
I loved building this set. Plus, it was very easy to motorize (easy to find on the internet), which I highly recommend doing. The orbital movements are beautiful! I like this so much that I now wish LEGO would come out with the entire Solar System as a large Technic Adults Welcome build! Go for it, LEGO!
As much as I dislike Technic Lego, the outcome is always super cool and workable, I recommend this to Technic fans.
This is a fun build that does not take to long to finish. It looks great and is quite enjoyable watching the Earth spin and go around the sun.
This is one of the best Technic models that I have built. I love the complexity and the reality of the, hummm, planetary drive train. The box says 10+ but I think it would be very challenging for a 10-year old without assistance, especially in the later steps with the sun, earth and moon need to be lined up. The action is not exactly accurate but does illustrate the position of the three bodies in orbit. I have made one hack to it by replacing the yellow orb with a 3" LED light. Next step is to motorize the drive train with a heavily reduced gearing to simluate the days and moon phases.
Was building this set and got to the top layer to assemble second orange ring and that piece is missing. Now we have a lego set sitting here unfinished as we can not complete it.
Added a motor and used Mindstorms to program the motor by using the left key to run the motor to simulate a lunar month and the right ket to run the motor to simulate a calendar year.
A beautiful model to help students understand a small part of how our planetarium works.
This set was very different from what we usually get but loved building it took a few hours , I find Lego can be very calming and really enjoyed this technic set and the instructions are very easy to follow , definitely a good set for older children and adults
It's fun to build, and also very educational, as you can see how the sun, moon, and earth work by turning them.
This set is super cool. Fun to build, very detailed, and also surprisingly accurate. Building took about 2hrs total. Took a bit of figuring out and adjusting to get the alignment just right, but troubleshooting and getting it to work is part of the fun! Once completed, the alignment of the months and moon phases are really spot on. Overall a really cool set to add to my collection (my first Technic set!), and I'd highly recommend this set to anyone. At $75 for the set, it's priced very reasonably.
I m so grateful I got this LEGO set to try thanks to LEGO and Influenster and I have to say I absolutely love it and my kids are having so much fun building it! It’s +10 technic so it actually moves are for older children so very safe. It’s so nice and you can actually teach your children with it.
