Select the statement that accurately compares galaxies and solar systems.
Both galaxies and solar systems are made up of multiple objects. Galaxies contain billions of stars, while solar systems have a star (or binary star).
Both galaxies and solar systems have planets that orbit their center.
Solar systems are made of a star (or binary star) and all the planets, moons, comets and other objects that are bound to the star by gravity. Galaxies only have stars, gas and dust inside them.
Galaxies have a single star (or binary star) at the center. Solar systems have billions of stars and planets that orbit them.
The correct statement is: “Both galaxies and solar systems are made up of multiple objects. Galaxies contain billions of stars, while solar systems have a star (or binary star).”
Explanation: A galaxy is a massive system that can contain billions of stars along with gas, dust, and dark matter. In contrast, a solar system is a smaller system that revolves around a single star (or a pair of stars, in the case of a binary system) and includes planets, moons, and other celestial objects bound by the star’s gravity. This distinction highlights the difference in scale between galaxies and solar systems.
