Galaxy vs. Solar system
Hundreds of billions of stars versus one star and its orbiting planets.
The comparisoni
“Mars is in another part of our solar system — both are in the Milky Way galaxy. The solar system is one star (the Sun) and its planets.”
The ruleii
¶
GALAXY = stars. SOLAR SYSTEM = one star + planets.
Our SOLAR SYSTEM has one star (the Sun), 8 planets, and many smaller bodies. The MILKY WAY GALAXY contains hundreds of billions of solar systems. Sci-fi blurs the scale; astronomy doesn't.
Memory aidiii
Remember it like this
Solar system fits inside galaxy.
