Jupiter is an unavoidable topic when it comes to the largest planet in the solar system. As the fifth planet in the solar system, Jupiter is several times more massive than the others and has a much larger diameter than the other planets. One of Jupiter's most striking features is its Great Red Spot, a massive storm system that has been around for at least a few centuries. Jupiter's atmosphere is mostly composed of hydrogen and helium, making it unique in the solar system. Jupiter also has at least 79 moons, the four largest of which are known as Galilean moons, which were discovered by Galileo in 1610 and provide important information for the study of Jupiter and its satellite system.
Let's turn to another fascinating celestial body, Saturn. Saturn is famous all over the world for its beautiful rings. These rings are made up of ice and rock particles that orbit the planet's equator. Although Saturn is not as large in diameter as Jupiter, it is still one of the largest planets in the solar system. Saturn is also known as a "gas giant" because its atmosphere is mostly composed of hydrogen and helium, similar to Jupiter. Saturn has at least 82 known moons, the largest of which is Titan, which has a moon called the Demon, which has an impact crater about 400 kilometers long, making it look like a winged wyvern.
Mars is the fourth closest planet to Earth in the Solar System and an object of much interest. The red color of the Martian surface is due to the presence of iron oxides, which give it the nickname "Red Planet". There are many landforms on Mars, including huge volcanoes, canyons, and impact craters. The most notable of these is the Olympus Volcano, the highest known volcano in the solar system, at about 22 kilometers high. Another striking feature is the Maria Canyon, which is larger than the Grand Canyon on Earth, measuring 4,000 kilometers in length and 7 kilometers in depth.
February** Dynamic Incentive Program Mars' atmosphere is very thin compared to Earth's, consisting mainly of carbon dioxide, which contains small amounts of nitrogen and argon. Due to the thin atmosphere, the air pressure on the surface of Mars is only about 1% of that of Earth. This causes the temperature on the surface of Mars to fluctuate widely, reaching around 20 degrees Celsius during the day but dropping sharply below minus 100 degrees Celsius at night. Due to the high concentration of carbon dioxide in the Martian atmosphere, it produces a phenomenon similar to the greenhouse effect, but because the atmosphere is too thin, this effect is not as strong as on Earth.
