The 2022 Winter Olympics were held successfully. Athletes(运动员)across the world came to Beijing and Zhangjiakou. Winter sports need to be in cold places. So, is it possible to hold the Winter Olympics on other planets?
Mercury(水星) It's the closest planet to the sun. In the daytime, the temperature can be 430℃. At night it cools down to -200℃. There's one area that the sun can never reach. There's lots of ice there. Maybe we could go speed skating there! |
Mars The temperature on Mars is between -140℃ and 30℃. At the north and south poles of Mars, there are areas covered by ice and snow. Some of the ice is made of carbon dioxide(二氧化碳), not water. There is also a big mountain called Mount Olympus. So maybe we can ski on Mars! |
Pluto(冥王星) Pluto is a small dwarf planet(矮行星)far away from the sun. It's very cold there, about -229℃. There's lots of ice. It's even harder than steel(铁). So maybe we could go sledding(滑雪橇)on Pluto. |
