Due to their great masses, all four Jovian planets are much denser than the earth.

• True

• False

Which characteristic listed below describes the jovian planets?

• Close to sun

• Small mass

• High density

• Solid Surface

• Fast rotational period

How do the densities of the jovian and terrestrial planets compare?

• Made from the same solar nebula, they are all similar.

• More massive jovians all have high densities, compared to the tiny terrestrials.

• All terrestrials are more dense than any of the jovians.

• 
  The closer a planet lies to the Sun, the less its density.

• No real pattern here; densities vary greatly and are very individual to each world.

In the proton-proton cycle, you must first make deuterium, then helium.

• True

• False
