The diameter of Saturn is nearly ten times that of Earth. However, the density of Saturn is much less than that of Earth. What is the reason for this?

• Earth is father from the sun than Saturn.

• Saturn has a ring system.

• Earth is hotter than Saturn.

• Saturn is a gaseous planet.

In 1995, the Hubble Space Telescope photographed a tiny spot in the sky for a period of ten days; 342 exposures were placed together to create an image known as the Hubble Deep Field. Although the sample is tiny, it is representative of the universe, which looks similar in all directions. The image below shows a collection of billions of stars. The Hubble Deep Field shows at least 3,000 groups of these stars.

• Moon

• Galaxy

• Universe

• Solar system

An astronomer uses a telescope to observe a star. She observes that the color of this star is similar to the color of the sun. Therefore, she infers that the star and the sun have similar sizes and surface temperature. Using this information, what can the astronomer conclude about the star?

• The star is a white dwarf.

• The star is medium sized.

• The star is hotter than most other stars in our galaxy.

• The star is brighter than most other stars in our galaxy.

Our solar system consists of eight planets. Each planet is classified as either a terrestrial planet or a gas giant planet. Which is a difference between these two types of planets?

• Terrestrial planets are larger than gas giant planets.

• Gas giant planets are denser than terrestrial planets.

• Terrestrial planets have thinner atmospheres than gas giant planets.

• Gas giant planets have rocker crusts than terrestrial planets.
