Final answer:
The Mars clans are not a recognized term, but if it refers to a grouping like constellations or planets, constellations are often named after mythological characters or animals, while planets and moons are usually named after gods and heroes from Greek and Roman mythology.
Step-by-step explanation:
The Mars clans are not a commonly recognized concept within astronomy or mythology, and there seems to be a misunderstanding in the question. However, interpreting the term 'clans' to possibly refer to groups or categories such as constellations or planets, we can proceed with relevant information.
In historical context, constellations are indeed groups of stars that were named after animals, mythological characters, or objects by the ancient Greeks and Romans. For example, Orion the hunter is a constellation named after a character from Greek mythology, and many other constellations follow this tradition. The Romans named the planets after their chief gods, such as Mars, Jupiter, and Saturn, following their observations of the 'wandering stars' in the night sky.
The zodiac constellations, falling within the ecliptic plane, were typically named after animals, which is where the term zodiac, related to 'zoo', originates from. Examples include Leo the lion, Aries the ram, and Scorpio the scorpion. However, planets and moons in our solar system are generally named after Greek and Roman gods and heroes, with some exceptions.
