Hey everyone, hope you enjoy my first Blender scene, the Solar System!
Cheers
Super idea ! looks great 
Amazing! you did a great job!
That looks great. 
As someone who loves anything outer space, I’m really liking what you did here. Well done indeed! 
Deserves more credit, GJ
Oh, it is great. How can you make the black line for path of planets ?
I think it’s a torus object(mesh( with a very very small width so it looks like a line
Thank you all for the comments, I appreciate! It was quite fun do the Solar System!
As for the lines, I simply added Curve > Circle, then scaled it to the right size. Placed the planets in the orbit by eye, they are not precisely aligned to them 
Looks awesome
