Gamma rays cause damage to cells of living organisms. To protect themselves people wear lead-lined clothes.

Ultraviolet radiation causes damage to cells of living organisms, which can cause certain types of cancers. To protect themselves, people wear hats and use sunscreens on their skin when they go outside.

Infrared radiation is produced by the Sun and causes things to heat up. People protect themselves by wearing warm jackets to prevent sunburn.

Visible light is produced by the Sun. People can protect themselves by living deep underground.

Each planet's orbit takes about the same amount of time.

Each planet's travels the same distance in it's orbit as the other planets.

Each planet's orbit is controlled by the pull of the Sun's gravity.
