Planets orbit the Sun in a shape called a(n)

• circle
• ellipse
• focus
• perihelion

When a planet orbits the Sun, one of the foci of the elliptical orbit is 

• the axis
• the perihelion
• the center
• the Sun

An ellipse is drawn around two points called

• aphelion
• perihelion
• foci
• axis

As the fuel in a rocket ignites, the force of gas expansion and explosion pushes out the back of the rocket and pushes the rocket forward.
