State True or False (T/F)A. The Moon and the planets are not the part ...
True or False: A. The Moon and the planets are not part of the solar system.
False
Explanation:
The solar system consists of the Sun, the planets, their moons, asteroids, comets, and other celestial objects that are bound by the gravitational force of the Sun. The Moon is Earth's natural satellite and is considered part of the solar system. Similarly, the planets, such as Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, are also part of the solar system.
The Moon: Part of the Solar System
- The Moon is Earth's only natural satellite.
- It orbits around the Earth, and both the Earth and the Moon orbit around the Sun.
- The Moon is considered part of the solar system because it is bound by the gravitational force of the Sun.
The Planets: Part of the Solar System
- The planets are celestial bodies that orbit around the Sun.
- They are not stars because they do not emit their own light but reflect the light of the Sun.
- The planets are considered part of the solar system as they are gravitationally bound to the Sun.
True or False: B. The Sun is the biggest star in our solar system.
True
Explanation:
The Sun is not only the center of our solar system but also the largest star within it. It is classified as a G-type main-sequence star, commonly referred to as a yellow dwarf. Here are some key points about the Sun being the biggest star in our solar system:
- Size: The Sun has a diameter of about 1.39 million kilometers, which is approximately 109 times the diameter of Earth. It accounts for about 99.86% of the total mass of the solar system.
- Light and Heat: The Sun is a powerful source of light and heat, providing the energy necessary for life on Earth.
- Nuclear Fusion: The Sun's immense gravity and pressure at its core enable nuclear fusion, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process.
- Other Stars: While the Sun is the largest star in our solar system, it is much smaller compared to other stars in the universe. There are many stars that are significantly larger and more massive than the Sun.
In conclusion, the Moon and the planets are indeed part of the solar system, and the Sun is the biggest star in our solar system.
