  What is the hottest planet in our solar system? A good guess might be Mercury, since it is the planet closest to the sun. But the correct answer is the next closest, Venus.
  Known as the Earth’s twin, Venus is similar to our planet in many ways. Both are about the same size, both have cloudy air, and both share some of the same landscape features: mountains, plains, and high plateaus. But while the earth has an average temperature of 14℃, Venus averages 462℃. What’s more, the temperature on Venus remains the same all over the planet, and it’s as hot at night as it is during the day.
  Why is Venus so hot? The answer lies in its thick air, the densest in our solar system. Thick yellow clouds fill the planet. The clouds get the sun’s heat in Venus’s air, so the planet is always hot. Many scientists believe that Venus once had oceans, just like the Earth, but they became air.
  太阳系中最热的行星是哪颗呢?一种猜测说是水星,原因是水星离太阳最近。但是正确的答案是离太阳第二近的行星——金星。
  众所周知,金星与地球好似一对双胞胎,在很多方面都相似。两颗行星的体积差不多大,都有云层,也有一些相同的地形特征:山、平原和高原。但是地球的平均温度是14℃,而金星的平均温度是462℃。更甚的是,金星的温度到处都一样,白天和晚上的温度也没有什么变化。
  为什么金星的温度这么高呢?答案在于其稠密的大气,金星上的大气是太阳系中最稠密的。星球上布满了厚厚的黄色云层,大气中的云层吸收太阳的热量,所以金星上的温度总是很高。许多科学家认为以前金星上有海洋,就像地球一样,只是后来海洋变成了大气。
