| Question | Answer |
|---|---|
| An object in space that circles around a planet | moon |
| Gravity between two objects is affected by these two things | mass and distance |
| The system of objects around the Sun | solar system |
| The path that one object takes around another | orbit |
| An object stays in orbit because the pull of gravity is balanced by this | inertia |
| Gravitational pull from this keeps the Earth in orbit | Sun |
| A mixture of ice, dust, and rock that circles the Sun | comet |
| An object that produces its own heat and light energy | star |
| The force of attraction between two objects | gravity |
| What do we call the smashing together of atoms in the Sun? | fusion |
| A rock that orbits the Sun, and lies in a belt between Mars and Jupiter | asteroid |
| Meteoroids that are caught by Earth's gravity and fall through its atmosphere | meteors |
| Is our Sun smaller than average, average, or larger than average compared to other stars in the universe? | average |
| Give the names of the planets in order of their distance from the Sun | Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune |
| What makes the planets stay in orbit around the Sun? | A planet stays in orbit because the pull of gravity is balanced by its forward motion (inertia) |
| The largest body in our solar system | Sun |
| What is the star at the center of our solar system composed of? | hydrogen and helium |
| This force is responsible for the orbits of the planets around the Sun | gravity |
| Name three other objects in the solar system, besides the Sun and planets | comets, asteroids, meteoroids |
