if it WERE to scale and we assume the Earth has a 1-inch radius on this model, the sun would have to be 18-feet wide and located something like 1950 feet away. That's a lot of Lego.

Space is big.

I saw this model built on display in a Target. The motion of the set is really cool.

That looks amazing! I'll put this on my son's Xmas wishlist, hopefully it doesn't sell out before Santa can deliver it.

Ugh, looks even better with the 3rd-party BrickBling LED light kit sold separately...

Did Lego actually get the gearing right for accurate moon phase and rotation? That's awesome!

Haha well done. I'd totally pay $60 for that.

Given that the Sun, Earth and Moon do not orbit on the same plane, not likely.

If I owned this, the set would annoy me every time I look at it due to the totally inaccurate printing of the earth. Last I checked, the equator does not pass through Mexico or northern Africa. Its like they enlarged everything in the northern hemisphere and shrunk everything in the southern hemisphere for some reason.
