Standards
• The solar system consists of planets and other bodies that orbit the Sun in predictable paths. As a basis for understanding this concept:
• 1.Students know the Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
• 2.Students know the solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.
• 3.Students know the path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.
