The sun and squirrels are made of matter.

The Sun is the central body of the solar system, and its mass accounts for the total mass of the solar system. The eight planets, asteroids, meteors, and comets known to mankind all revolve around the Sun, and the Sun revolves around the center of the Milky Way.

The diameter of the Sun is about 1,392,000 kilometers, which is 109 times the diameter of the Earth; It is about 130 times the size of the Earth; The mass is about 330,000 times that of the Earth.

In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including less than 2% of the mass of oxygen, carbon, neon, iron and other heavy elements, which release light and heat into space by means of nuclear fusion.

The Sun is a yellow dwarf, a yellow dwarfThe lifespan is roughly 10 billion years, for nowThe sun is about 100 million years old。In about 50 to 6 billion years, the Sun's interior will be almost completely depleted of hydrogen, and the Sun's core will collapse, causing the temperature to rise, a process that will continue until the Sun begins to fuse hydrogen into carbon.

The Sun was formed about 100 million years ago in a cloud of collapsed hydrogen molecules.

The Sun does not have enough mass to explode into a supernova, replacing it with a red giant stage about 5 billion years later.

The Sun is a huge, red-hot planet of gas.

From the volume and mass of the Sun, it can be calculated that the density of the Sun is gram centimeters , which is about a multiple of the average density of the Earth.

The Sun, like other celestial bodies, rotates from west to east on its axis.

Sunlight is the main source of energy on Earth.

Squirrels belong to the family of rodents, a large group of rodents with fluffy tails, with about 58 genera and 285 species distributed on all continents except Antarctica.

The average lifespan of a squirrel is between 4 and 10 years.

In China, the Northeast region and Xinjiang taiga are the natural ranges of the Eurasian red squirrel. Rock squirrels are found in broad-leaved forests and mixed coniferous and broad-leaved forests in North China.

In the cold north, some squirrels hibernate in their nests like voles and bears; In the warmer south, squirrels generally do not hibernate but store food for the winter, and squirrels can still be seen in winter activity. The daily start time of squirrels was related to sunrise time, but there was no significant correlation between end time and sunset time. The daily activity rhythm of squirrels is affected by the climate, and strong winds, heavy rains, and severe cold and heat will reduce the squirrel's activity time.

Squirrels spend 70 to 80 percent of their time foraging.

Squirrels live alone most of the time.

This contrast gives the reader the impression that it is more specific than the exact figures. 3. Illustrate the visualization.

When introducing the characteristics of the sun's "heat", the text first uses the metaphor of a "big fireball" to vividly reflect the shape of the sun, its luminescence, and its heat.

Characteristics of ; Then he pointed out that the surface temperature of the sun is 6,000 degrees, and how much should 6,000 degrees be.
