A planetarium display allows visitors to select two regions of space.
| Region | Objects shown |
|---|---|
| X | One star, the Sun; planets and dwarf planets orbit the Sun; moons orbit some of the planets |
| Y | The Sun and billions of other stars, many of which have their own planets |
A visitor says, “Regions X and Y must be the same structure because the Sun appears in both.”
Evaluate the visitor's claim. In your answer, name the galaxy represented by region Y.
