Titania, named after the queen of the fairies in Shakespeare's "A Midsummer Night's Dream", is the largest moon of Uranus and the eighth largest moon in our solar system. Its discovery in 1787 by Sir William Herschel marked a significant advancement in our understanding of the Uranian system.
Orbiting the Ice Giant:
Titania orbits Uranus at a mean distance of approximately 291,000 miles (468,000 km), completing a full revolution around the planet every 8 days, 16 hours, and 56 minutes. This relatively close orbit means that Titania is constantly under the influence of Uranus's powerful gravity.
A World of Mystery:
Despite its relatively large size, Titania remains shrouded in mystery. While telescopes have revealed its presence and orbital characteristics, its actual diameter is still uncertain, with estimates ranging from 980 to 1,610 kilometers.
Unveiling the Secrets:
To understand Titania better, scientists rely on observations from various space missions, including the Voyager 2 spacecraft which flew past Uranus in 1986. These missions have provided valuable data about the moon's surface composition, revealing a heavily cratered landscape with signs of past tectonic activity and possible volcanic eruptions.
The Future of Exploration:
As technology advances, we can expect more detailed observations of Titania. Future missions to the Uranian system could provide close-up images, revealing intricate details of its surface and potentially uncovering evidence of past or present geological activity.
In Summary:
Titania, a mysterious and intriguing moon of Uranus, continues to hold secrets waiting to be unveiled. As our understanding of this celestial body grows, we can expect fascinating insights into the history and evolution of the Uranian system and the diverse range of celestial bodies that populate our solar system.

Instructions:
The diameter of Titania is estimated to be between 980 and 1,610 kilometers.
**Earth's moon diameter:** 3,474 km (approximately) **Titania's diameter as a fraction of Earth's moon:** * **Minimum:** 980 km / 3,474 km ≈ 0.28 (about 28% the size of Earth's moon) * **Maximum:** 1,610 km / 3,474 km ≈ 0.46 (about 46% the size of Earth's moon) **Comparison:** Titania is significantly smaller than Earth's moon, with a diameter ranging from less than one-third to nearly half the size of our own lunar companion.
