Structure of the Sun

The Sun is the star at the center of the Solar System and it was formed about 4.57 billion years ago. It has a diameter of about 1,392,000 kilometers (865,000 mi) (about 109 Earths), and its mass is 330,000 times that of Earth. About three-quarters of the Sun's mass consists of hydrogen, while most of the rest is helium. The Sun's color is white and is the brightest object in the sky. A miniature book with many informations about the sun is attached to this paper craft.

Sundial

Sundial

A sundial is a device that measures time by the position of the Sun. This papercraft model is modeled on a horizontal sundial, so the sun casts a shadow from its style onto a flat surface marked with lines indicating the hours of the day. As the sun moves across the sky, the shadow-edge progressively aligns with different hour-lines on the plate.
