8. A myth/legend circles around that of Pluto. In your own words, tell the tale of this myth. (4)

Charon is the person who took the dead across the River Styx to Hades (Roman name is Pluto). Therefore, it is fitting that they go hand in hand together as planet and satellite.

7. Many astronomers speculate that it is a comet, and part of the Kuiper belt as its composition is similiar to other comets in the belt.
It is very small. It's 6 times smaller than Earth, and even smaller than seven of the solar system's moons.

8. Pluto ruled the shadowlands. He took Persephone into the underworld. Demeter ensured the earth became barren until Persephone's safe return.

A compromise was reached where she spent part of the year in the underworld and part of year on earth, hence the seasons of summer and winter.

Pluto's symbolism is about change and transformation through the painful process of finding truth and meaning. It also corresponded with the rise of depth psychology.

You can see that pluto looks cold and dark and lonely. It looks dead, like there is no life to it.
