The Solar System
Bayani Gaba-gaba
Day and night, the march of the seasons, the changing face of the Moon: the great rhythms of the sky all come from a few simple motions. The Earth spins, the Earth orbits the Sun, and the Moon orbits the Earth, and from those three facts the whole pattern follows.
In this lesson you will use the Earth's tilted spin to explain day and night and the apparent motion of the Sun, its yearly orbit to explain the seasons, the Moon's monthly orbit to explain its phases, and the orbital-speed equation to calculate how fast a body moves around its orbit.
