I can help with that. Here is the correct comparison of the relative sizes of astronomical bodies:
A galaxy is larger than a solar system because a galaxy typically contains billions to trillions of stars along with various celestial bodies like planets, moons, asteroids, and comets. In contrast, a solar system consists of a single star (like our Sun) and all the objects that orbit around it, such as planets, moons, asteroids, and comets. The size difference between a galaxy and a solar system is vast, with galaxies being significantly larger in scale due to the sheer number of stars and celestial bodies they encompass.
Remember, when comparing the sizes of astronomical bodies, it's essential to consider the composition and scale of each type of object to accurately determine their relative sizes.
