Our solar system includes our sun, as well as the planets and other objects that orbit it. It was formed approximately 4.5 billion years ago and contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Originally, Pluto was classified as the ninth planet and farthest from the sun; however, in 2006, the International Astronomical Union redefined the necessary characteristics of a planet and in doing so excluded Pluto.
The sun contains 99.9% of the mass of the solar system and thus induces the other planets to orbit around it. The four innermost planets encircling the sun are relatively small. Immediately beyond them in the solar system is a rocky asteroid belt. Looking further out in the solar system one can find the largest planets, known as the gas giants. Many of the planets have secondary systems that include moons or planetary ring systems.

Based on the information in the passage, which of the following statements is FALSE?
 

C. The sun contains approximately 100 times as much mass as everything else in the solar system.

Explanation

The correct answer to this question will be one that is not supported by the evidence in the passage. Process of Elimination is a good strategy to use for questions like this one. According to the passage, the outermost planets are the larger ones, so eliminate (A) and (B). The passage does not speculate on the likelihood of life on other planets—(D) is neither supported nor contradicted so it is eliminated. The passage states that the sun contains 99.9% of all mass in the solar system, indicating that it is about 1,000 times as massive as everything
