Remix from FritzPeppone's Solar System Lithophane Planet Lamps.

I made these parts to hang all planets around sun in the ceiling and to add led strips inside them.

Electrical box is not included. I had one lying around and made some holes in the cover to attach middle section with screws and route wires inside.

You need “Generic Fairy Light Socket” from ⌀75mm planets for led sticks to go in and my E14 adapter for bigger planets. I attached led strip pieces to sticks with zip ties.

You also need 10mm diameter wooden stick that you cut to length you want and attach them to stick connector in the middle and add wire end cap to all ends. I cut them to 250mm for bigger planets and 400mm for smaller ones.

Sun in the middle has E27 smart light bulb inside so I can set it bright enough to work as room main light source and also change color to orange and dimmer to look nice in the evening.

I printed Sun in 200mm diameter
Jupiter, Saturn, Uranus and Neptune in 150mm and
Earth, Venus, Mars and Mercury in 75mm.

For wiring you basically need power supply and ESP32 with WLED installed inside your electrical box.
Connect all led strips inside planets together in line (I used 4 wire cable so its positive, negative, data in and data out). 
Connect them to ESP32 and power supply. Then wire power supply and light bulb of the sun to wiring on the ceiling. 
You also need to configure start and end led pixel of each planet in WLED controller, set segments to each planet and you can control colors of all planet individually.

I used QuinLED-Dig-Uno as WLED controller because it has everything you need prebuild. Data wire is too long to be controller with bare ESP32. You need atleast level shifter paired with it.

Wiring all this is not easy task and shouldn't be done without professional and you still need to figure out some plastic box for electronics and how to mount it to ceiling.
