With the big eclipse coming in another couple of weeks, I just had to buy this set. As an engineer, I truly appreciate the effort that went into this design. It was extremely impressive!! I only wish that it was designed to be expandable in a manner where other planets could be added in the future. That would have been beyond awesome!

This is a fun and interesting build that really showcases what Technic can do when it thinks outside of the box. I built it with my young kids helping/watching and it was an interesting set both to build and to explain the seasons when it was done. Well done Lego!

This is a fun little build that helps you envision how the earth and moon revolve around the sun and each other. I think the detail on the earth's landmasses could be more accurate. The little strip stickers that you put on ar difficult to align properly. I must have applied mine wrong because the moon phases indicated don't line up with the actual moon position as it rotates. I thought I was careful to align stuff correctly, but maybe not. Stil it's a fun piece

I put the Planet Earth and Moon in Orbit set together in two comfortable sittings. As always with Lego, the assembly instructions are excellent. I'm a longtime Lego fan, mostly collecting and building the modular buildings and winter village sets. I have some experience with Technic, such as the mechanisms in the Haunted Mansion and roller coasters. But I haven't done the big Technic sets before. This set is pure Technic, and I found it a joy to assemble. I expected the earth to rotate on its axis and revolve around the sun. And I expected the moon to orbit the earth. These functions work masterfully and make it easy to understand the seasons and the moon phases. One unexpected delight was the rotation of the sun. The real sun rotates faster at its equator than its poles, but this Lego model does a great job representing the overall rotation, and quite accurately. While building this model, I was struck by the excellent engineering that went into getting the gear and shaft mechanisms correct. The model is sturdy and operates smoothly. But the model is also artistic, with an elegant appearance. I recommend this to families, to science teachers, and to anyone who appreciates good design and wishes to learn about the relationships among our earth, moon, and sun.

This is a very cool set and very cool to build. However Lego missed the mark with the stupid stickers. Come on LEGO...Do better. You have this advertised as PRINTED graphics however as usual they are STICKERS and NOT PRINTED. Why Lie? This isn't going to deter me from getting other sets but you have to do better for your customers. Either be honest or do what it says.
