Study Notes
The Earth and the Solar System
The solar system consists of the sun, eight planets, and their moons. The sun is at its center and is the primary energy source, making life on Earth possible. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, with Jupiter being the largest and Mercury the smallest. Mercury is closest to the sun, while Neptune is the furthest. Satellites, which can be natural or artificial, orbit planets, with the moon being Earth's only natural satellite. Stars, including the sun, are large, self-luminous bodies made of burning gases. Kalpana Chawla, an Indian-born American astronaut, was the first woman of Indian origin in space. Pluto was reclassified as a dwarf planet by the IAU. Earth's rotation causes day and night, while its revolution precedes seasons. Sunlight takes about 8 minutes to reach Earth.
