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

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!

the amount of frustration i went through trying to find ONE piece was actually crazy, i stayed up to 1:30 in the morning trying to find this ONE TINY GEAR that was missing. i almost cried myself to sleep and i was so close to finishing it too.

My grandson was literally “ OVER THE MOON” when he opened the box with this Lego set inside. He thought I had used the empty box to wrap a different item!!! His delight was boundless! He focused entirely on the project and completed it in two days! WIN! Win!

l love the Space themed Lego so when l saw this set l had to have it. The price is a little high but once you start building it's worth it! The mechanism is very complicated but straightforward if you follow the instructions carefully. Once completed the model operates well and is great to turn the handle and watch it all working. A few have commented that it isn't to scale. Of course it isn't, it would be impossible. But the timings are correct including the moon phase, which is amazing. And someone commented that the model is incorrect because in reality the "sun doesn't rotate in relation to the Earth" Yes it does. The sun rotates once every 27 days. And the model is again accurate in this respect.

This was super fun to build and the after look was great. I loved all the little detail Lego made and they did a great job. Highly recommend.

It was really fun, but a little hard to build. I’d suggest this for people who are maybe 13 and up.

I’d been on the lookout for a set like this for a while (space, mechanical, Technic) and was so happy when this was announced - even happier putting it together! I put it together once myself and then had my students assemble it shortly after to coincide with a total solar eclipse that occurred in our area. I’ve put together many sets with my classes over the years (Haunted House, Crane Truck, ISS to name a few), but this was the first that really captured the engineering spirit I try to reinforce in many of my lessons. It was straight up too hard for quite a few students who couldn’t follow directions or recognize one gear instead of another. In my opinion though, that was perfect as it afforded those who did understand the opportunity to tear it down and problem solve with their classmates. I’ll never forget the look of accomplishment on the student who finished it when they turned the crank and it worked - truly magical. Anyways, thank you for making this set - would love to see something mechanical for other branches of science!
