The tiny circle (1) in the center of the smallest square is now the moon's orbit.
The earth's position is marked by a dot, although the dot is much too large and
actually the earth would be invisible on this scale. Its orbit (2) is now clearly
curved. Under the earth's orbit another curve (3) is drawn. That is the orbit of
the planet Venus, which moves around the sun as the earth does and in the
same direction: in this drawing, from right to left. The size of the sun, if it were
drawn at this scale, would be 1.4 millimeters. We will repeat here that the
black area of the above square would in reality be studded with a multitude of
stars. We leave them out in this drawing and in the following drawings for the
reason stated earlier.
1 cm. in picture = 1012 cm. = 10,000,000 km. | Scale = 1:1012 |
