Comparing Size And Composition

Phobos and Titania, two celestial bodies in our solar system, differ in terms of size and composition. Let’s delve into each moon’s unique characteristics and discover how they contrast with one another.


Phobos, the larger of Mars’ two moons, is an intriguing celestial object to study. Measuring approximately 22.2 kilometers in diameter, it is one of the smallest moons in our solar system. Despite its diminutive size, Phobos is about seven times larger than its counterpart, Deimos.

When it comes to composition, Phobos primarily consists of carbonaceous chondrites with a blend of rock and ice. This composition suggests that it may have formed from a mix of water ice and primitive material that existed in the early solar system. However, the exact origin of Phobos is still a subject of scientific debate.


Taking a leap from Mars to Uranus, we encounter Titania, the largest moon of the seventh planet in our solar system. With a diameter of approximately 1,578 kilometers, Titania is the eighth-largest moon in our solar system.

Titania’s composition primarily comprises rock and ice, similar to other moons in the Uranian system. However, scientists have also detected traces of water on its surface, which adds to the moon’s composition and potential for harboring organic compounds.

It’s worth noting that Titania’s larger size compared to Phobos allows for better exploration and study. Scientists have been able to gather substantial data and insights about Titania’s geological features and surface conditions through various space missions.

Size And Composition Comparison

In comparing Phobos and Titania, the most striking difference lies in their size. While Phobos is relatively small, Titania stands as one of the largest moons in the solar system. This significant variation in diameter directly impacts their compositions, with Phobos primarily consisting of carbonaceous chondrites and Titania predominantly composed of rock and ice.

Phobos Titania
Diameter Approximately 22.2 kilometers Approximately 1,578 kilometers
Composition Carbonaceous chondrites, rock, and ice Rock, ice, and traces of water

While Phobos’ smaller size limits our understanding, the contrasting sizes and compositions of these moons provide valuable insights into the diversity and evolution of our solar system.

Understanding Their Orbits

Understanding the orbits of Phobos and Titania is essential for comprehending the unique characteristics of these two moons. Their orbits not only define their behavior but also contribute to their distinct qualities and interactions with their parent planets.

Phobos’ Orbit

  • Shape: Phobos’ orbit is markedly elliptical, making it closer to Mars at certain points and farther away at others.
  • Speed: It completes a revolution around Mars in only 7 hours and 39 minutes, which is faster than a Martian day.
  • Deimos: Its proximity to the smaller moon, Deimos, influences its gravitational interaction with Mars.

Titania’s Orbit

  • Distance: Titania has an eccentric orbit, meaning its distance from Uranus varies during its revolution around the planet.
  • Period: It takes approximately 8.7 Earth days to complete a single orbit around Uranus.
  • Gravity: Titania’s orbit is influenced by the gravitational pull of Uranus and possibly the other moons of the planet.

Unraveling Their Origins

Unraveling the origins of Phobos and Titania, the two intriguing moons in our solar system, has been a captivating pursuit for astronomers and scientists. Exploring the distinct theories surrounding their formation offers a glimpse into the complex and enthralling history of these celestial bodies.

Phobos’ Origin Theories

Our neighboring Red Planet’s moon, Phobos, is shrouded in enigmatic origin theories that have captivated the scientific community for decades. Here are the leading hypotheses:

  1. The Capture Hypothesis: Suggests that Phobos was a wandering asteroid that Mars’ gravitational pull captured, incorporating it into its orbit.
