Answer:
1. Jupiter is the biggest planet in the solar system.
2. The outer planets such as Jupiter, Saturn, Uranus, and Neptune are called Jovian Planets.
3. Saturn is the sixth planet from the sun.
4. Neptune has 13 moons, the largest of which is called Triton.
5. Uranus is the first planet discovered by the means of telescope.
Explanation:
1. Jupiter 61.42 billion km².
2. The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune.
3. Saturn is the sixth planet from our Sun (a star) and orbits at a distance of about 886 million miles (1.4 billion kilometers) from the Sun.
4. Triton is the largest of Neptune's 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago.
5. When Uranus, the seventh planet from the Sun, was discovered in 1781, it expanded the known limits of our solar system. It was also the first planet to be discovered using a telescope, as Mercury, Venus, Mars, Jupiter and Saturn were all bright enough to be easily visible to the naked eye.
