The Solar System is...

• Small, natural objects that revolve around other larger objects

• The force of attraction by which terrestrial bodies tend to fall toward the center of the earth

• Made up of a star, the planets, and other space objects that revolve around it

• Large, round bodies that revolve around a star

Planets are...

• Small, natural objects that revolve around other larger objects

• The force of attraction by which terrestrial bodies tend to fall toward the center of the earth

• Made up of a star, the planets, and other space objects that revolve around it

• Large, round bodies that revolve around a star

Moons are...

Asteroids are...

• Rocky, airless worlds that orbit our sun, but are too small to be called planets. Tens of thousands of these minor planets are gathered in the main asteroid belt, a vast doughnut-shaped ring between the orbits of Mars and Jupiter.

• A group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure

• Cosmic snowballs of frozen gases, rock, and dust roughly the size of a small town. When a comet’s orbit brings it close to the sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the sun for millions of kilometers.
