LEGO® Technic Planet Earth and Moon in Orbit 42179 (10+ Yrs)

Got this set for my 5 year old, she really enjoyed how the whole thing came together and the gear work in it. She was really happy to learn more about the solar system, had a long discussion about it after building the set.

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.

My kids love this set. My oldest figured to spin the sun to speed through the years. Honestly, I prefer reeling in the years. Just another joy with extreme replay value.

The instructions booklet for this is missing steps and pieces necessary for it to work completely. I took it apart twice to find fixes for issues with the gears, and still can't make it work properly. Know that if you follow the assembly instructions exactly, you will not have a working final product. Use the spare pieces and a few extras laying around, and you might get it working properly.

It's a fun build. I would like it if there was a way to show I labeled and did everything correctly. How do I know the earth and moon phases are correct? I also very much dislike having to apply stickers.

Really fun to build and play with. I would definitely recommend this set

I've had this set on my wishlist for a while now. Every time I see it in stores I just WANT it so badly!!! Finally made the purchase, and I'm so happy! Watching it come together was such a joy...sure, it was a bit tricky (a few times I had to triple check a step) but it looks so cool! Definitely in my top 10 favorite sets!

5 different rotations all being controlled by one crank. It's incredibly accurate! My only beef and it's very subtle... the phases of the moon are depicted from the southern hemisphere and without using scissors on the stickers, there isn't much you can do. I think Lego should offer a northern hemisphere sticker set.

This was an incredible set to put together. I hope we see more sets like it.

I got this set had fun building it and after it was all built I counted the rotations of earth and lunar cycles and they were both spot on with the real numbers. With the total earth rotations being at 365 and the the total lunar cycles being 12.

Impressed by the model in general, the only thing I found funny was how America was printed since the equator seems to go across Mexico

I loved the building experience of this and I love how it does so much with quite little pieces

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!
