Meditações - os movimentos da Terra

The Earth moves in three different directions at the same time.

1. It rotates upon its own axis with a speed of about 500 yards per second diminishing from the center towards the Poles.

2. It revolves around the sun with a speed of about 19 miles a second.

3. It participates in the sun's own forward motion in the direction of the fixed star, Vega, in the constellation of Lyra, with a speed of 12 miles per second.

All simultaneously.

A fourth movement in wich the earth probably participates is that of the sun's own rotation upon its axis wich is accomplished once every 25 days.

A fifth movement - that of the whole stellar system upon its axis - is possible - but doubtful.
