Which planet is identified as the sixth planet from the Sun?

1. Neptune

2. Uranus

3. Saturn

4. Jupiter

The correct answer is: Saturn

The sixth planet from the Sun is Saturn. This classification is based on the arrangement of the planets in our solar system, which are positioned in the following order from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Saturn is well-known for its prominent ring system, which is the most extensive and complex of all the planets in our solar system. Its gaseous composition and massive size also contribute to its distinct characteristics. As a gas giant, Saturn primarily consists of hydrogen and helium and is the second-largest planet in terms of diameter. In discussing the other options, Neptune, Uranus, and Jupiter are positioned differently in the solar system: Neptune is the eighth planet, Uranus is the seventh, and Jupiter is the fifth. Each of these planets has unique features and importance in the study of astronomy, but in terms of their order from the Sun, they do not share the same position as Saturn. Thus, Saturn accurately represents the sixth position when considering the planets from the Sun.
