SOLAR SYSTEM
A solar system is a collection of celestial bodies that are gravitationally bound to a central star. In our case, the solar system refers to the system cantered around the Sun. The solar system is located in the Milky Way galaxy and is part of a larger galactic structure. The main components of a solar system include the following.
- Star: The central star (the Sun in our solar system) provides the gravitational force that holds the system together and supplies energy to the other bodies.
- Planets: Large celestial bodies that orbit the star. In our solar system, there are eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
- Dwarf Planets: Smaller planetary bodies that orbit the star and meet some criteria of planets but do not clear their orbits of other debris (e.g. Pluto, Eris, Ceres, Haumea and Makemake).
- Moons: Natural satellites that orbit planets and dwarf planets. For example, Earth’s Moon orbits Earth, and Jupiter has many moons, including Ganymede, the largest moon in the solar system.
- Asteroids: Rocky bodies primarily found in the asteroid belt between Mars and Jupiter. They are remnants from the early solar system.
- Comets: Icy bodies with highly elliptical orbits that, when close to the Sun, develop a glowing coma and tail due to the sublimation of their ices.
- Meteoroid: A small, rocky or metallic body in space, typically smaller than an asteroid but larger than a grain of dust. It originates from comets or asteroids and orbits the sun.
- Kuiper Belt and Oort Cloud: Regions beyond Neptune filled with small icy bodies and remnants from the early solar system. The Kuiper Belt is a disk-shaped region, while the Oort Cloud is a more spherical shell surrounding the solar system.
