Planetary Science review

Where would I look in the solar system to find planets made mostly from rock and metal?

• Near the sun (inner planets)

• Far from the sun (outer planets)

• Trick question -- the rocky planets are not clustered together

• Trick question -- none of the planets are made from rock and metal.

Where would I look in the solar system to find planets containing very large amounts of Hydrogen?

• Near the sun (inner planets)

• Far from the sun (outer planets)

• Trick question -- the Hydrogen planets are not clustered together

• Trick question -- none of the planets are made from Hydrogen

Where would I look in the solar system to find planets containing very large amounts of water?

• Near the sun (inner planets)

• Far from the sun (outer planets)

• Trick question -- the watery planets are not clustered together

• Trick question -- none of the planets are made of water

Where would I look in the solar system to find planets that are mostly made of Carbon?

• Near the sun (inner planets)

• Far from the sun (outer planets)

• Trick question -- the Carbon planets are not clustered together

• Trick question -- none of the planets are made of Carbon

Which description is the best way to define a planet's "orbit"?

• Inertia causes planets to move in straight lines, but the sun's gravity deflects a planet's inertia towards the sun.

• Gravity causes planets to move in straight lines, but the sun's inertia deflects a planet's gravity towards the sun.

• Gravity works best when a planet is at a specific distance, so the planets maintain a circular orbit to maximize gravity's effect

• Inertia requires that planets keep moving the way they have been moving. Since the planets had circular orbits when they formed, inertia keeps them moving in circles.

How are Pluto and Ceres similar? (Select all TRUE statements)

• Both objects are today classified as "dwarf planets"

• Both objects were initially considered planets until later discoveries showed that each object was part of a "belt" of many similar celestial bodies.

• Both objects are located in the Inner Solar System

• Both objects are named after Roman gods or goddesses

• Both objects are mostly made from metal

What is the relationship between a planet's distance from the sun and the length of that planet's "year"?

• The further a planet is from the sun, the longer its year will be.

• The closer a planet is to the sun, the longer its year will be.

• The length of a year depends on the specific attributes of each planet -- there is no trend here.

• All planets require the same amount of time to orbit around the sun.
