๐ The Earth orbits the Sun at an average speed of about 107,000 kilometers an hour.
๐ The geocentric model, which placed the Earth at the center of everything, was based on ancient Greek philosophers' ideas.
โญ The geocentric model failed to explain why planets changed brightness and occasionally moved in different directions.
๐ The geocentric model explained planetary motion using epicycles and imaginary points.
โญ๏ธ Copernicus developed the heliocentric model where the Sun is the center of the universe.
๐ The heliocentric model was a more accurate representation of the Earth's position in the cosmos.
๐ The heliocentric model proposed by Copernicus had Mercury, Venus, Earth, Mars, Jupiter, and Saturn orbiting the Sun, with the Moon orbiting Earth.
๐ Johannes Kepler discovered that planetary orbits are actually ellipses, not circles, which supported the heliocentric model.
๐ญ Galileo Galilei's observations with his telescope, particularly of Jupiter and its moons, provided strong evidence for the heliocentric model.
๐ The geocentric model predicted that Venus would be closer to Earth when it was new, but it was actually closer when it was full.
๐ The heliocentric model proposed that the Sun, Venus, and Earth lined up so that Venus would be closer to Earth when it was new.
๐ The heliocentric model was initially banned, but eventually accepted. However, it is now known that both Earth and the Sun orbit the center of mass of the solar system.
๐ The geocentric model, which suggests that Earth is at the center of the solar system, is wrong.
๐ญ Telescopes, probes, and humans going into space have confirmed that the Sun is at the center of the solar system.
๐ก The Sun's mass and the position of the planets affect the center of mass in the solar system.
