Two Celestial Centuries - 1500-1700 AD.

Below is a chart of showing the Time-line of five major figures in early astronomy. During this period western civilization developed

• heliocentric view of the solar system
• accurate astrometric measurements and star charts
• the laws of planetary motion
• telescopic astronomy
• discovery of satellite of other planets
• laws of mechanical motion
• law of gravity
• determination of comet orbits
