2. TERMS TO KNOW
Sun: a star at the center of a solar system Orbit: the path of one object as it revolves around another object. Planet: a spherical object that orbits a star. A planet’s orbit is an ellipse (oval, elongated to near circular in shape). Moon: object(s) that orbit a planet. Solar System: one star and all objects that orbit that star. [Note: our solar system consists of the sun, nine planets, their moons, and comets/asteroids that revolve around the sun].

3. Models of the Solar System
Geocentric (earth-centered): earth is at the center and the stars and planets revolve around Earth. Heliocentric (sun-centered): sun is at the center with the Earth and planets revolving around the Sun. Galileo’s telescope evidence supported this model of the solar system.

5. The Sun The Sun’s (any star’s) energy is powered by Nuclear Fusion:
the process where
hydrogen atoms join
together under the
influence of gravity to
form helium and huge
amounts of energy
(radiation) is released
into space.
