🔭 Explore Space

Orbit
Orbit / Órbita
The curved path an object takes around another object in space due to gravity.
🔗 Planets orbit the Sun in predictable paths
Gravity
Gravity / Gravedad
The force that pulls objects toward each other. The Sun's gravity keeps planets in orbit.
🔗 Keeps planets orbiting the Sun!
Inner/Outer
Planet Types / Tipos de Planetas
INNER (Rocky): Mercury, Venus, Earth, Mars - solid surface, smaller, closer to Sun. OUTER (Gas/Ice Giants): Jupiter, Saturn, Uranus, Neptune - mostly gas/ice, much larger, many moons.
🔗 Two main groups of planets!
Light
Reflected Light / Luz Reflejada
Planets do NOT make their own light! Only the Sun produces light. Planets reflect the Sun's light - that's how we see them in the sky.
🔗 Planets shine by reflecting sunlight!
Revolution
Revolution / Revolución
One complete trip around the Sun. Earth's revolution takes 365 days (1 year).
🔗 Creates our year
