Study Notes
Planetary Characteristics
- Earth is the densest planet in the solar system.
- Uranus has a uniquely tilted rotational axis, nearly lying in the plane of its orbit.
- Venus holds the title for the highest average surface temperature among planets.
- Mercury is the closest planet to the Sun, while Saturn has the lowest average density.
Distance from the Sun
- Objects in increasing proximity to the Sun rank as follows: Pluto, Saturn, Jupiter, Mars, Earth, Mercury.
- The planet Neptune orbits about 30 times farther from the Sun than Earth.
Mass and Size Rankings
- The ranking of solar system objects by mass, from highest to lowest: Sun, Jupiter, Earth, Mars, Mercury, Pluto.
- Size ranking (average equatorial radius) from largest to smallest: Sun, Jupiter, Earth, Mars, Mercury, Pluto.
Planetary Orbits and Temperatures
- Neptune takes the longest time to orbit the Sun, followed by Jupiter, Mars, Earth, and Mercury, which has the shortest orbital period.
- In terms of surface temperature ranking from highest to lowest: Mercury, Earth, Mars, Jupiter, Neptune.
Moons and Planets
- Jupiter has the most moons, with the order of planets by number of moons as follows: Jupiter, Mars, Earth, Mercury.
- Mars is unique as the only rocky planet with more than one moon.
Planet Types and Formation
- Terrestrial planets (like Earth and Mars) are expected to be found closer to their star compared to jovian planets (like Jupiter and Saturn).
- Compared to terrestrial planets, jovian planets are characterized by being more massive and having lower average densities.
Distinctions of Dwarf Planets
- The dwarf planets Pluto and Eris are smaller and less massive than terrestrial and jovian planets and travel in more elliptical orbits.
Solar System Structure
- The solar system is made up of eight major planets along with dwarf planets such as Ceres, Pluto, and Eris.
- Orderly motions in the solar system are characterized by planets closer to the Sun moving at higher speeds, nearly circular orbits, and orbits lying in the same plane.
Composition of Small Bodies
- Small bodies in the solar system are classified as asteroids when rocky and comets when icy, highlighting the diversity of solar system composition.
