Explanation: 'Ophelia' is one of the natural satellites (moons) of the planet Uranus. To understand this concept, it is important to first grasp the structure of the Solar System and the characteristics of the planets within it.
Uranus is the seventh planet from the Sun and is one of the four gas giants in the Solar System. It is known for its unique axial tilt, which causes it to rotate on its side. Uranus has a complex system of rings and moons. As of the latest observations, Uranus has 27 known moons, which are named after characters from the works of William Shakespeare and Alexander Pope.
'Ophelia' is one of the smaller inner moons of Uranus. It was discovered in 1986 by Voyager 2, a space probe launched by NASA. Ophelia is approximately 42 kilometers in diameter and orbits Uranus at a distance of about 53,790 kilometers from the planet's center. It is part of a group of moons known as the "Portia Group," which includes other small moons such as Cordelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, and Belinda.
Understanding the moons of Uranus is crucial for comprehending the dynamics of the outer Solar System. Each moon has its own unique characteristics, such as size, composition, and orbital properties. The study of these moons helps scientists understand the formation and evolution of the Solar System.
In contrast, Earth has only one natural satellite, commonly known as the Moon. Mars has two small moons, Phobos and Deimos, while Pluto, which was once considered a planet, has five known moons. The confusion might arise from the fact that many moons in the Solar System share similar names or characteristics, leading to misconceptions about which moon belongs to which planet.
In conclusion, 'Ophelia' is correctly identified as a moon of Uranus, based on the established astronomical data and the specific characteristics of the Uranian moon system. This knowledge is essential for students studying the Solar System and planetary science.
