3. Share your fact file in class.
答案
1. Answers for the 3 points:
1. The solar system is made up of the Sun and 8 planets that orbit around the Sun, and the Earth is the third planet from the Sun.
2. The Sun is a star that is far hotter and larger than the Earth, and its diameter is about $1.392×10^6$ kilometers.
3. There are a huge number of tiny rocky objects called asteroids in the asteroid belt between Mars and Jupiter.

2. Sample fact file about the solar system
Fact File of the Solar System
| Category | Details |
|---------|---------|
| Central Star | The Sun: A yellow dwarf star, accounts for 99.86% of the total mass of the solar system, surface temperature is about 5500℃ |
| Inner Rocky Planets | 1. Mercury: The smallest planet, closest to the Sun, no natural satellite
2. Venus: The hottest planet, with a thick carbon dioxide atmosphere, rotates in the opposite direction of most planets
3. Earth: The only known planet with life, has one natural satellite (the Moon)
4. Mars: Called the "Red Planet", has polar ice caps made of dry ice and water ice |
| Outer Gas/Ice Giant Planets | 1. Jupiter: The largest planet in the solar system, has a famous Great Red Spot which is a lasting giant storm
2. Saturn: Well-known for its beautiful bright rings made of ice particles and rock debris
3. Uranus: Tilted by 98 degrees on its orbit axis, rolls around the Sun like a ball
4. Neptune: The farthest planet from the Sun, has the strongest wind speed in the solar system that can reach 2100km/h |
| Other Special Members | Asteroid Belt: Located between Mars and Jupiter, with millions of small celestial bodies
Comets: Made of ice, dust and rock, will form a long glowing tail when approaching the Sun |
3. Sharing hint
You can introduce the fact file to your classmates in plain and lively language, show the most interesting points you find (for example, the special rolling rotation way of Uranus) to arouse the curiosity of other students, and discuss more interesting solar system knowledge together.
