"Sun Family" PPT

Part One: Problem Exploration

1. Which celestial bodies are moving around the sun?

2. What are the characteristics of these celestial bodies?

3. How are they arranged?

The solar system is a celestial system composed of the sun, planets orbiting the sun, dwarf planets, small celestial bodies (comets, asteroids, meteoroids and interplanetary materials) and satellites orbiting the planets. The sun is the center of the solar system. In the huge solar system family, the mass of the sun accounts for 99.8% of the total mass of the solar system, and the eight major planets and tens of thousands of asteroids account for a negligible proportion. Such a large mass attracts other members around it to revolve around it. At the same time, the sun generously and selflessly dedicates its light and heat, warming every member of the solar system and promoting their continuous development and evolution.

A star is a star that can emit light and heat by itself.

Summary: planets, dwarf planets, comets, asteroids, meteoroids, interstellar matter, satellites

Part Two: Definition of Planets

2. Near ball shape

3. Clear the track

Eight planets:

Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune

Part Three: Planets in the Solar System

The boss of the solar system-the sun

The sun is the center of the solar system. In the huge solar system family, the mass of the sun accounts for 99.8% of the total mass of the solar system. The eight major planets and tens of thousands of asteroids account for a negligible proportion. The sun's huge energy comes from its core, which is less than 500,000 kilometers in diameter. The temperature and pressure in the core are extremely high, and a nuclear energy reaction occurs, releasing huge amounts of energy. It is estimated that the sun can burn for 10 billion years. The sun is the only body in the solar system that can emit heat and light. It is a star

Well-deserved-Mercury

Mercury is the closest to the sun and often appears and goes out at the same time as the sun. It has a very thin atmosphere. Mercury has no satellites. Because Mercury is very close to the sun, its surface temperature can be as high as 450 degrees Celsius during the day; it plummets to as low as 450 degrees Celsius at night. One hundred and seventy degrees Celsius. It's called Mercury but it doesn't have a drop of water.

golden planet-Venus

Venus, also known as the morning star, is the brightest planet in the sky and the closest planet to the earth. Venus has a thick atmosphere and can often be seen at dawn or dusk.
