Solar System Structure and Components
📌 The Solar System consists of the Sun and all celestial bodies orbiting it, based on the heliocentric theory proposed by Nicolaus Copernicus.
☀️ The Sun is classified as a star because it is capable of emitting its own light.
☄️ Celestial bodies orbiting the Sun include planets, asteroids, and comets; asteroids are rocky fragments containing little metal, often grouped in the asteroid belt between Mars and Jupiter.
🌌 Comets are also known as "tailed stars," and their tails always point away from the Sun due to solar wind and radiation pressure.

Meteoroids, Meteors, and Meteorites
🌠 Fragments of asteroids and comets become meteoroids floating freely without orbiting a major body.
🔥 A meteoroid burning up in Earth's atmosphere is called a meteor.
🌍 If a meteor survives the descent and hits the Earth's surface, it is called a meteorite, capable of creating large impact craters.

Classification and Characteristics of Planets
🪐 Planets in the Solar System are divided into inner planets and outer planets, separated by the asteroid belt.
🌎 The Inner Planets (Mercury, Venus, Earth, Mars) are closer to the Sun, while the Outer Planets (Jupiter, Saturn, Uranus, Neptune) are further away.
⚫ Mercury is the closest and smallest planet, with a size only 40% of Earth's.
🔥 Venus is nicknamed the Morning and Evening Star; it is the hottest planet due to a dense carbon dioxide atmosphere causing a strong greenhouse effect.
🔴 Mars is known as the Red Planet due to iron oxide on its surface.
👑 Jupiter is the largest planet, measuring 10 times the size of Earth.
🌀 Saturn is recognizable by its rings composed of dust, pebbles, and ice; Uranus has an axial tilt of 98°, making it appear to roll during rotation.

Earth's Movements and Their Effects
🔄 Rotation is Earth's spin on its axis, moving from West to East (counter-clockwise), completing a cycle in 24 hours (one day).
☀️ Earth's rotation causes day and night (day when facing the Sun, night when facing away) and the apparent daily motion of the Sun (rising in the east, setting in the west).
🌍 Due to Earth's slightly oblate shape (bulging at the equator and flattened at the poles), and its tilt, there are time zone differences across countries.
↩️ Revolution is Earth's orbit around the Sun, taking 365.25 days (one year).
📅 Revolution, combined with the Earth's 23.5° axial tilt, causes the apparent annual motion of the Sun (moving between Northern and Southern hemispheres) and seasonal changes.
☀️ The Sun is directly overhead at the culmination point twice a year: March 21st and September 23rd.
🌡️ The axial tilt causes varying solar intensity: when the Northern Hemisphere is tilted toward the Sun, it experiences summer (longer daylight hours), and the Southern Hemisphere experiences winter, and vice-versa.

Key Points & Insights
➡️ The Solar System operates under the heliocentric model established by Copernicus.
➡️ The division between inner and outer planets is defined by the asteroid belt located between Mars and Jupiter.
➡️ Earth's rotation determines the length of the day and the cycle of day/night, while revolution dictates the year length and the seasons due to the 23.5° axial tilt.
➡️ Venus is the hottest planet, primarily due to a massive greenhouse effect from its $\text{CO}_2$ atmosphere.
