A very nice orrery / technic kit
This is a wonderful “orrery” kit. Mechanically it is fascinating to watch. WIth a little work a lego/third party motor can be attached so you can watch it spin around on its own. The Sun, the Earth and the moon spin accurately. A very excellent manual is enclosed to detail the orrery’s function. It’s a fun build, not a super hard build but should be suitable for people who have done Technic style Lego builds in the past.Other than the first-generation Mindstorms kits, this is my favorite “Technic” Lego kit ever.I should add that typically orreries cost a few hundred dollars. As long as you like Lego, this is by far the most affordable planetary model I found!

Space Lovers Lego
My nephew is in love with stars and planets and he just so happens to enjoy legos. This is the trifecta, he loved the whole process of building it and using the crank to see how the rotations work. Great Lego set.

This set offers an engaging build experience with a clever mechanical system that simulates the orbit of the Moon around Earth, making it a perfect choice for space enthusiasts and budding engineers alike.The assembly process is enjoyable and satisfying, featuring Technic elements that provide a hands-on way to understand orbital mechanics. The build quality is solid, and once completed, the rotating function works smoothly, adding a dynamic element to the display. The details on Earth and the Moon are beautifully crafted, with accurate representations and vibrant colors that make it a great educational piece for kids and adults.One of the standout aspects of this set is how it seamlessly combines playability with an educational component. Itâs a great way to spark curiosity about space and planetary motion. The only minor downside is that it requires careful alignment to ensure smooth operation, but with a little patience, it works beautifully.Pros:Engaging and educational designSmooth orbital movement with Technic gearsHigh-quality build with attention to detailGreat display piece for space loversCons:Requires careful assembly for optimal functionalityMight be too simplistic for experienced Technic buildersOverall, the LEGO Technic Planet Earth and Moon in Orbit set is a fantastic addition for anyone interested in space, science, or engineering.

Fun to build
Fun and quick to build. Would be nice if they supplied a motor for it. Be careful with the central black gear that turns the main arm — it’s easy to reverse.

Superou minhas expectativas. Para além de ser um mero brinquedo de montar peças, é um excelente instrumento de ensino em três dimensões sobre os movimentos de nosso planeta terra em relação ao sol e a lua. O mecanismo que permite o giro deles é muito preciso em relação aos marcadores. Eu e minha filha vibramos com o produto!
