Study Notes
The Inner Planets of the Solar System
- The inner planets of the solar system are Mercury, Venus, Earth, and Mars, which are closer to the Sun than the outer planets.
- Mercury, the closest to the Sun, has a diameter of approximately 4800 kilometers and no natural satellites.
- Venus, the second inner planet, has a unique clockwise rotation, a surface temperature of 870 degrees F, and is named after the Roman goddess of love.
- Earth, the third inner planet, has a rotation period of 24 hours, a magnetic field, and is 70% covered by water, with one large satellite, the Moon.
- Mars, the fourth inner planet, is known as the red planet, has a diameter of about 6800 km, a temperature range from -220 to 70 degrees F, and two moons.
- The inner planets formed from protoplanets, with high temperatures allowing the metal and rock to condense, unlike the outer planets that formed from a combination of ice, gas, and rock.
- Composed of silicates and metals, the inner planets have atmospheres and weather, except for Mercury.
- The inner planets have slower orbiting speeds despite being closer to the Sun, and a maximum of two moons, with Mercury and Venus having none.
- Differences between inner and outer planets include size, density, composition, moons, rings, and orbital speed.
- The inner solar system consists of the four inner planets and the asteroid belt.
- Inner planets are denser, made of iron, nickel, and silicates, and lack rings, while outer planets are made of gas, ice, and rocks, have dozens of moons, and rings around them.
- The inner planets share characteristics such as formation, composition, orbits, and more, distinguishing them from the outer planets.
