- 1.
- 2. Sun Our star, theheart of the system, holding everything in orbit with its gravity. A ball of fire, mainly hydrogen and helium, generating immense energy. 4.6 billion years old and 109 times Earth's mass. Crucial for life on Earth, providing warmth and light.
- 3. Mercury Rocky and cratered,closest to the Sun, with scorching days and freezing nights. No moons.
- 4. Venus Hottest planet, shrouded inthick atmosphere, has volcanoes and active geology. No moons.
- 5. Earth Moon Asteroid Belt Unique bluemarble, our home, teeming with life, with liquid water oceans and diverse climates. One moon. The Moon, Earth's sole natural satellite, has captivated humanity for millennia.
- 6. Mars The "Red Planet,"cold and dusty, with evidence of past water and potential for future exploration. Two moons. The majority of the asteroids in our Solar System can be found orbiting the Sun in the asteroid belt, which is a region of space located between Mars and Jupiter's orbits. Asteroid Belt
- 7. Jupıter Europa King of theplanets, massive gas giant with swirling storms, the Great Red Spot, and numerous moons.
- 8. Saturn Ringed wonder, famous forits dazzling ice and rock rings, boasts many moons and a complex atmosphere.
- 9. Uranus Tilted gas giantwith icy blue methane clouds, faint rings, and several moons.
- 10. Neptune Farthest planet, alsoa gas giant, known for supersonic winds, dark storm spots, rings, and multiple moons.

Key features The Earth is stationary at the center of the universe The Sun, Moon, planets, and stars all orbit the Earth The heavens are ethereal and unchanging All motions in the sky follow circular paths History The geocentric model was common in ancient Greece, where it was embraced by Aristotle and Ptolemy It was also prevalent in the Islamic Golden Age It was generally accepted until the 16th century It was gradually replaced by the heliocentric model of Copernicus, Galileo, and Kepler Hi! I’m Aristotle
- 12. helioCENTRIC MODEL The heliocentric modelis a theory that states that the sun is at the center of the universe and that the Earth and other planets orbit around it. The term comes from the Greek word helios, which means "sun". Contributions to astronomy The heliocentric model led to new findings, such as the orbits of Mercury and Venus. The model revealed why these planets appear so different in size and shape over time. History The heliocentric model was first proposed by the Greek astronomer and mathematician Aristarchus of Samos in the 3rd century BC, and Galileo Galilei supported the idea. Nicolaus Copernicus published the model in 1543 in his work On the Revolutions of the Celestial Spheres. The model was initially pieced together without a telescope . Copernicus thought planets moved in perfect circles too I’m Galileo “and yet it moves”
