Winter sports need to be in cold places. Have you ever imagined one day people go to other planets to hold the Winter Olympics?
Mercury (水星) is the closest planet to the sun. In the daytime, the temperature can be up to 430℃, but at night it cools down to -160℃. There's one area that the sun can never reach. There's a lot of ice there. Maybe we can go speed skating and figure skating (花样滑冰) there! | |
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. There is also a big mountain called Mount Olympus. So maybe we can ski on Mars! | |
Pluto(冥王星) is a dwarf planet far away from the sun. It's very cold there, about -229℃. There's a lot of ice. It's even harder than steel. So maybe we can go sledding (滑雪橇) on Pluto. |
