Planet and Solar System Myths People Still Believe
Many people still hold surprising beliefs about planets and the solar system that science has long since updated.
1. Mercury is the hottest planet because it’s closest to the Sun
Truth: Venus is hotter due to its thick carbon dioxide atmosphere that traps heat.
2. The Great Wall of China is visible from space, but Earth’s features aren’t
Truth: Many features like cities, roads, and rivers are visible from space, but the Great Wall is actually hard to see.
3. Pluto is no longer part of the solar system.
Truth: Pluto is still in the solar system; it’s now classified as a dwarf planet, not removed entirely.
4. The Moon has a dark side that never receives sunlight
Truth: The far side of the Moon gets sunlight, we just never see it from Earth.
5. Saturn is the only planet with rings
Truth: Jupiter, Uranus, and Neptune also have rings, but they’re just fainter and harder to see.
6. You’d instantly freeze in space
Truth: You’d lose heat slowly in a vacuum through radiation. You’d suffocate before freezing.
7. The Sun is a giant ball of fire
Truth: The Sun creates energy through nuclear fusion, not by burning like fire.
8. Mars is red because it’s hot
Truth: Mars is cold. Its red appearance is due to iron oxide (rust) on its surface.
9. The asteroid belt is crowded and dangerous to travel through
Truth: Asteroids are spread out over vast distances, and spacecraft pass through them safely.
10. Gravity is the same on all planets.
Truth: Gravity varies. For example, you’d weigh less on Mars and more on Jupiter.
