Some Common Misconceptions
Some common misconceptions about the relation between the earth and the sun
- The earth's orbit around the sun is a highly elongated (skinny) ellipse,
making the distance between earth and sun vary dramatically over the course
of a year.
- The sun is pretty far off-center within the earth's orbit, making the distance
between earth and sun vary with time of year even more.
- The seasons are controlled by the distance between the earth and sun. During
winter, the earth is farther from the sun than in summer.
- The tilt of the earth's axis of rotation puts the Northern Hemisphere significantly
closer to the sun in June than the Southern Hemisphere (producing summer in
the Northern Hemisphere and winter in the Southern Hemisphere).
