Which statement is true about Jovian planets?
Jovian planets have longer periods of rotation than Terrestrial planets do
Jovian planets are made mostly of gas and have a high density
Jovian planets have shorter periods of revolution than Terrestrial planets do
Jovian planets are larger in diameter but small in density than Terrestrial planets are
When Earth orbits around the sun, it slows down when it is farther from the sun. It speeds up its orbit when it is closer to the sun. This is because the sun's gravity is stronger when you are closer to it.
The Milky Way galaxy is best described as
a type of solar system
a constellation visible to everyone on Earth
a region in space between the orbits of Mars and Jupiter
a spiral-shaped formation composed of billions of stars
The red shift of visible light waves that is observed by astronomers on Earth is used to determine the
sizes of nearby galaxies
relative motions of distant galaxies
densities of the planets
rotation periods of the planets
The reaction represents an energy-producing process.
The reaction represents how energy is produced
in the Sun by fusion
when water condenses in Earth’s atmosphere
from the movement of crustal plates
during nuclear decay
Which of the following stars is the least bright?
the Sun

Compared to the terrestrial planets, the Jovian planets have
smaller diameters
slower rates of rotation
greater average densities
longer periods of revolution
Which graph best indicates the densities of the planets in our solar system?
The diagram below represents the orbits of three planets (X, Y, and Z) around star A. Star A is located at one focus and point B is the other focus. Numbers 1 through 9 represent different positions of the three planets. The arrows show the direction of revolution.
