    Wonderful engineering
    All Legos are wonderfully engineered-- I always marvel at the fit and precision of these little plastic blocks! But this orrery really appeals to me, and the gear train is a marvel. For the number of gears and shafts involved, the mechanism has remarkably low friction, it moves so easily and smoothly!I only regret rushing through the build without noting the gear train layout. Being a fan of orrerys, I may go back and draw it out with all the gear tooth counts and ratios.Lego missed a couple educational opportunities here. The manual has no info on the history of orrerys, how they work, gear trains in general, what concepts the orrery demonstrates.

    This was a really fun build. My 10 year old son put it together and really enjoyed adding all the gears and seeing it all come together. The end result is really impressive! Watching all the gears turn as the earth rotates is mesmerizing. We’ve already talked about moon phases and the change of the seasons, which are so easy to demonstrate with this model.

    If you love space and LEGO, the Technic Planet Earth and Moon in Orbit Building Set is an absolute must-have! Here's why I loved it:

    Challenging Build: This set offered a delightful challenge with lots of fun gear mechanisms. Putting the intricate workings of the model together was both satisfying and engaging.
    Educational Experience: I learned a ton while building this! Being able to see how the Earth and Moon orbit the Sun makes the concepts easy to visualize. The details, like printed months and moon phases, are a great touch.
    Scientific Accuracy: While not perfectly to scale, I was impressed by how accurately the model represents the relative motions of the Earth, Moon, and Sun.
    Overall, this set is not only enjoyable to build, but it's a wonderful learning tool too. If you have a curious kid interested in space, or you're an adult space fan yourself, this LEGO set won't disappoint. Highly recommended!
