Between the Earth and Mars there is a china teapot revolving about the sun in an elliptical orbit. The teapot is too small to be revealed even by our most powerful telescopes.
Let's start drawing it from the lid. This is the easiest way to maintain proportions, and nothing will need to be erased.
The second step is to draw the bulbous body of the teapot under the lid. From the lid, the line goes slightly down, and then symmetrically follows an oval shape to the opposite side of the lid.
All that remains is to add the handle, spout, and base.
