It is about 20.5 light years from our earth. They estimated the planet's average temperature at between 0 and 40 degrees Centigrade. It is orbiting the red dwarf star, Gliese 581.
It means that it must always show its same face to its sun, and that while one side would be too fiercely hot to support life, the other side would be too cold.
这就意味着它面对红矮星的一面会太热不适合生命体而背对红矮星的一面则会很寒冷。
Autumn is the harvest season , the paddy fields and trees are covered with golden color.
秋天是丰收的季节,金黄铺满了稻田洒满了枝头。
We should cherish it, instead of polluting it, spoiling it or even destroying it.
我们要珍惜它,夕阳西下,
So the astronomers believe that it is potentially habitable.
所以科学家们相信它能支持生命的存在。
So, let us protect our earth with our love, making it better and more harmonious.
