Ashley missed a day of school while the teacher discussed hierarchical relationships. How would you describe the order from smallest to largest?

• Universe, planet, solar system, galaxy, comet

• Planet, comet, solar system, galaxy, universe

• Universe, galaxy, solar system, planet, comet

• comet, planet, solar system, galaxy, universe

Explain why astronomers use light years or astronomical units to describe the distance a star is away from earth.

• The federation of astronomers decided this system was the most economical.

• Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable.

• Light years and AU's are more like space names.

• There are not enough zeros to describe the distance properly.

• A universe because it contains billions of stars and the planets.

• A solar system because it contains planets and stars.
