Study Notes
- The solar system consists of the sun and eight unique planets that orbit around it.
- The sun is a star, approximately 93 million miles away from Earth, and takes about 8 minutes for its light to reach Earth.
- The planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, each with its own characteristics.
- Planets have oval-shaped orbits around the sun, with different orbital periods; for example, Earth takes about 365 days to orbit the sun.
- Planets also rotate on their axes, determining the length of a day; for example, one day on Mercury equals 60 Earth days.
- Some planets have moons while others do not; Earth is the only known planet supporting life in the solar system.
- Jupiter is the largest planet with at least 79 moons, followed by Saturn with 53 moons and distinctive rings made of ice chunks and rocks.
- Uranus, an ice giant, rotates on its side and has 13 rings, while Neptune, another ice giant, has a thick fog of water, ammonia, and methane, with 13 moons and 6 rings.
