While it may not be the most displayable set it's still technically very impressive. Amazing how well it simulates the spin of the earth while the monthly markings a really nice touch adding to the educational value of the set. Also looks very easily motorized.
Yep.. I replaced the handle with a gear and that's it for modding this build for me. Now I can use my old Lego train controller and a 35 year old Lego motor with wormgear attached to it to motorize it by putting the wormgear on top.😅 But the train controller and 35 year old motor look ugly so next month I'm gonna order a modern Lego motor and battery pack for this set.
Awesome. I plan on getting this set and finding a way to motorize the function so that it aligns with the Earth. Basically, I'd make it to where the model completes one revolution when the actual Earth completes a revolution. But I'm still working out the kinks. Anyway, super cool set!
Got the set yesterday. Already motorized it!😂 One of the coolest space sets I own! It's cool to have a Lego space set that isn't another spaceship or moon base or rover!😄 Ow.. and here are some facts about the rotations: I replaced one of the pins on planet Earth with a pin that is 3 long so I could put a red door on it as an indicator for the rotation of the earth and I counted slowly... And I did that 3 times because in science you need to repeat stuff over and over to compare results. The Earth in this set takes 352 rotations to do a full orbit around the sun and the moon takes 27 Earth rotations to do a full orbit around the Earth. In real life it's 365 days for Earth and 29,3 days for the moon. So pretty close if you look at the limitations with Lego gears and the number of teeth they have.👍 One thing I really dislike with this set... Planet Earth itself! it's completely wrong!!😅 The size of the continents is all wrong and so is their position. Try explaining seasons to someone from Africa or Mexico with this set.. it won't work because the continent is in the wrong place😅
I also purchased the set and calculated the gear ratios. One of the important points is that since some gears have axles that rotate respective to the base frame, it is technically a planetary gear system. The crane rotates at 1/121.5 of the input crankshaft. The 20-tooth gear (1) that transmits power to the crane rotates at 1/3 of the input, which is 79/243 measured from the rotational frame of the crane. The sun rotates at 1/3 of that angular velocity respective to the crane. Thus, respective to the base frame, the sun rotates at (1/3)(79/243)+2/243 = 85/729 of the input. The revolution of the moon in this set has the same angular velocity as the rotation of the sun, which means that a sidereal month takes 729/85 cranks. The rotation of the earth, in this model, is powered by the 24-tooth gear below it, which rotates 3 times for each rotation of the 20-tooth gear(1), measured in the frame of the crane. thus, the 24-tooth gear rotates -79/81 time for each crank input (negative sign indicates that the gear rotates in opposite direction as gear(1) ). Measured in the base frame, this corresponds to -235/243 rotation each crank input. The earth rotates at thrice that speed in the positive direction in the base frame. Summary: 1 crank on base = 1/121.5 years = 85/729 solar rotation or sidereal month = 235/81 sidereal day 1 year = 14.1667 sidereal month = 13.1667 synodic month 1 year = 352.5 sidereal day = 351.5 solar day
I have just finished building this set but it doesn’t work. Me and my stepdad noticed one problem and fixed it but then we noticed two more problems that we have not idea how to fix. Should I just take it apart and rebuild it?
This looks really educational and cool. Probably the first time I have seen technic do a model that is not a car, a plane or a rover.
Finally real Lego technic , where real technology is also installed.
Need more sets like this!!
Agreed

Wow, looks very interesting, I love the details and stickers of the months and moon phases, looks very interactive!
I was mystified as to where some parts went and was able to watch your video on slowest speed and find the answer. Thanks!
This is really unique. Never seen a technic set like this from Lego.
Love these sets lego are making now
Awesome review! I will get this lego set next week really exited!
okay but at 3:45 did your white piece go in the bottom part? if it does mine doesnt fit
Bro me too , did u fix it since this comment was 8 months ago, I can't get it and I'm genuinely annoyed and sad
@ hell no lmao, i got the part on but then my dog chewed a piece and now i cant finish the lego set💀😭
@@DylanCoreas-y6c Make sure you're using the 12 tooth gear instead of the 20 tooth gear, that was my mistake. Hope this helps :).
This Lego set is not only interesting, but also useful
5:02 really cool, but I can’t get the small gear to spin with the mechanism

Did you manage to motorise the set? I would like to aswell, but not experienced with Lego motor parts!! Thanks
Lego Technic 2024
Planet Earth and Moon in Orbit

Super set!
SO AWESOME!!!!! 😄👍🌟
Can’t believe they made this when JK Brickworks made the same thing but way prettier a while ago and put it on LEGO Ideas.
I've made a similar design off that and not realised I predicted the set DIY 😐 but instead it has Venus and Saturn 😮
I’m building this right now I’m in the arm that holds the earth 😂
Looks awesome set 👍🎶
so coool!!! Now I must know the gear ratio to know how accurate (ish) is the movement hahahaha
Probably the first set in the series that is not a vehicle
Lego Technic were also the first series of Bionicle in 2001 :)
that's nice to hear :)
Such a cool one!! We plan to buy mid month! 🎉
I wonder how accurate this is mathematically
From what I read it's 1.75 days short per year (364.5 instead of 366.25 sidereal days) and 8 hours on the moon (27 instead of 27.3 days)
@@Stereomoo Huh, surprisingly accurate!
Moon orbits at 5 degrees to ecliptic so the model show way too many eclipses :-(
@@spudgossie Ah :(

Summary:
1 crank on base = 1/121.5 years = 85/729 solar rotation or sidereal month = 235/81 sidereal day
1 year = 14.1667 sidereal month = 13.1667 synodic month
1 year = 352.5 sidereal day = 351.5 solar day
LEGO should really bring back those Star Wars planet sets
Wow
Nice dude mz and Eli
this was no easy design as all the gears have to be timed so as the spheres aligned properly for the moon phases, the earth seasons, etc...
I have it right next to me and I’m using it
How long has it been since we got a Technic set that wasn't a vehicle? This looks really cool, I just think it's priced a little bit too high
8:15
I always love lego technic they look awsome as display pieces with gimmicks

sana sa susunod na lego technic na irelease e yung solar system naman yung theme 🚀🚀🚀🌌🌌
so it is not rotating automatic ?
Thanks brother for sharing !! Just let u know that Lego Harry potter 76430 and 76426 it out on sale.
the sun spins too ?
Hey my earth doesn’t spin??? Some gears aren’t either please help
My one is leaning for some reason
Looks like the Watch from Jacob and Co astronomia
Next can be kawasaki ninja please
Lego if your watching this make the solar system
An interesting fact is that in fact, this set is plagiarized from the Lego Idea website, just without other planets.
Sun, Earth, and the Moon in Orbit. In other words: an Orrery.
i just went down the wikipedia rabbit hole of why it's called an Orrery. fascinating!
Wait ?!!! The earth is not flat ????
Try to review, unboxing and Speed build 42170 Kawasaki H2R
Will come......
ดี
People who miss B Models? Anyone? 😢
Sorry Lego - Flop hoch 10, CADA hat die bessere Lösung im Design, Funktion und Preis!
It's certainly very cool but definitely ugly... it looks unfinished and not displayable.
