The solar system is a collection of celestial bodies that are bound together by gravity. It consists of the Sun, eight planets, moons, asteroids, comets, and other objects.
The Sun is the center of the solar system and the largest object. It provides light and heat to the planets and other celestial bodies. It is a massive ball of hot gases, primarily hydrogen and helium.
There are eight planets in the solar system, divided into two groups: terrestrial planets (Mercury, Venus, Earth, and Mars) and gas giants (Jupiter, Saturn, Uranus, and Neptune). Each planet has its own unique characteristics and features.
Many of the planets in the solar system have moons (or natural satellites) orbiting around them. For example, Earth has one moon, while Jupiter has over 70 moons.
Asteroids are rocky objects that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter. Comets are icy bodies that travel through the solar system, leaving a trail of gas and dust behind them when they approach the Sun.
There are various ways to study the solar system, including telescopes, space probes, and spacecraft missions. Scientists continue to make new discoveries and learn more about the solar system and beyond.
The student demonstrates an understanding of the theories regarding the origin and evolution of the universe by recognizing that objects appear smaller the farther away they are.
The student demonstrates an understanding of the theories regarding the origin and evolution of the universe by recognizing that objects have properties, locations, and movements that can be observed and described.
