How do we know the Sun rotates?
• Here is a hint:
Sunspots move across the sun, disappear and reappear on the other side.

How are asteroids like comets and how are they different?
• Comets are round with a tail.
• Asteroids are pieces of rock with an irregular shape.
• Comets are ice, dust, and gases.
• Asteroids move in an orbit between Jupiter and Mars.
• Both orbit the sun, smaller than a planet, are space objects.
