What is orbiting (or revolving)?
A type of planet made mostly of rocky material with a solid surface

The shape of Mercury's orbit
What is elliptical (or oval)?
What Venus has that causes it to maintain a higher temperature than Mercury even though it is farther from the sun
What is an atmosphere?
A word used to describe how God designed the distance, mass, rotation, atmosphere, land, magnetosphere, and tilt of Earth
What is perfect?
An object in space, either artificial or natural, that orbits another object.
What is a satellite?
A giant explosion on the Sun that sends massive amounts of energy, light, and high-speed particles into space

These are the eight planets in our solar system.
What are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune?
What is a solar eclipse?
What mercury lacks and causes it to have extreme differences in night and day temperatures...as high as 800 °F and as low as -290 °F
What is an atmosphere?
The rotation of Venus as compared to all other planets in our solar system
What is the opposite direction?
The five layers of Earth
What are the crust, upper mantle, lower mantle, outer core, and inner core?
