About complex from simple: Theon of Smyrna wrote: The changing aspects of the revolution of
the planets is because, being fixed in their own circles or in their own spheres whose movements
they follow, they are carried across the zodiac, just as Pythagoras had first understood it, by a
regulated simple and equal revolution but which results by combination in a movement that
appears variable and unequa

Back 4

iThe summer solstice occurs when the tilt of a planet's semi-axis, in either the northern or the southern hemisphere, is most inclined toward the star (sun) that it orbits. Earth's maximum axial tilt toward the sun is 23° 26'. This happens twice each year, at which times the sun reaches its highest position in the sky as seen from the north or the south pole.

What is meant by the plane of the solar system?

Back 8

kThe angle between the orbital planes of the Earth and Moon is about 5?. Eclipses occur when the Moon crosses the path of the Earth's plane so that the Sun, Earth, and Moon are all lined up in the same plane. Since this angle is so small, for the purpose of this experiment we will consider the Moon, Earth, and Sun to all lie in the same plane.
