Part 1: Importing new lessons

In addition to the earth and the moon, what other celestial bodies do we know that move around the sun? What are the characteristics of these celestial bodies? How are they arranged?

Solar System PPT, Part 2: Exploring New Knowledge

The celestial body system with the sun as the center and including the eight planets (including satellites orbiting the planets), dwarf planets, and small celestial bodies (including asteroids, meteors, comets, etc.) orbiting it is called the solar system.

sun

The sun is the only star and luminous celestial body in the solar system. It is the central object of the solar system. 99.86% of the mass of the solar system is concentrated in the sun.

The diameter of the sun is approximately 1,392,000 kilometers, which is equivalent to 109 times the diameter of the Earth; its volume is approximately 1.3 million times that of the Earth.

The eight planets in the solar system

There are eight planets orbiting the sun in the solar system, including: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

All eight planets orbit the sun from west to east.

Mercury

Mercury, known as Chenxing in China, is the smallest planet among the eight planets and the innermost and smallest planet in the solar system, but it is still 1/3 larger than the moon.

Mercury is the fastest moving planet in the solar system.

Unless there is a solar eclipse, Mercury is usually not visible in sunlight.

Venus

Venus is the closest planet to Earth. People in China call it "Taibai Venus". The surface temperature of Venus is very high.

Venus's rotation is very special. It rotates in the opposite direction to other planets. It is the only major planet in the solar system that autorotates in reverse. Venus has no natural satellites.

Solar system PPT, part three: expansion and extension

Why was Pluto "downgraded"?

Reasons why Pluto was expelled

Pluto:

First, its size is too small, its mass is only 1/3 of the moon;

Second, the orbit is too elliptical;

Third, the orbits of the eight stars are almost on the same plane, and the inclination angle between the orbital planes of Pluto and the eight stars reaches 17 degrees.

Solar System PPT, Part 4 Content: Summary of this Lesson

1. The sun and the planets, dwarf planets and small celestial bodies orbiting it form the solar system. The solar system is a larger celestial system.

2. The basic structure of the solar system is mainly determined by the movement and distribution of the eight planets. In order from closest to far from the sun, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
