"Solar System" Universe PPT

Part One: Understanding the Solar System

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.

In this family, the planet closest to the sun is Mercury, followed in order outward by Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

There are hundreds of thousands of asteroids of various sizes and shapes between Mars and Jupiter. Astronomy calls this area the asteroid belt.

The sun is a hot gas planet with an internal temperature of up to 15 million degrees Celsius and a surface temperature of about 6,000 degrees Celsius. The size of the sun is equivalent to 1.3 million earths.

A planet like the sun that can generate its own light and heat is called a star.

Mercury is the closest to the sun and often appears and disappears at the same time as the sun. It has a very thin atmosphere. The temperature during the day can reach 450°C, and the temperature at night drops to -170°C.

Venus is slightly smaller than Earth and can be considered Earth's sister planet. The time it takes for Venus to rotate once is equivalent to 243 Earth days, but the time it takes for it to orbit once is only equivalent to 225 Earth days. In other words, a "day" on Venus is longer than a "year". Venus spins in the opposite direction to the rest of the solar system.

Venus has a thick carbon dioxide atmosphere. Carbon dioxide makes it difficult for the heat on the surface of Venus to dissipate into space. The stored solar energy makes the surface of Venus become hotter and hotter. The temperature on the surface of Venus can reach a maximum of 447°C.

The earth is our beautiful and fertile home. The existence of life on the earth makes the earth different from other planets and becomes the most special celestial body in the solar system.

Mars is far away from the sun, so its air is thinner and its surface temperature is cooler. Whether there is water on Mars has always been the focus of astronomers from all over the world.

Solar system PPT, part 2: Build a model of the solar system

According to the relevant information of the eight planets, use plasticine to shape a ball to represent the eight planets, and try to build a model of the solar system in a certain order and proportion.

Reduce the distance between the planets and the sun in the table by the same proportion, and arrange the "sun" and the "eight planets" on the table. What is the difference between the "solar system" we see and the "solar system" we usually see in pictures?

The distances between the eight planets are too different, and the distances between the planets are not basically equal as shown in the diagram.

We only reduce the distance between the eight planets and the sun according to a certain proportion, think of ourselves as the eight planets, let us revolve around the sun and build a dynamic solar system model!
