正如我们太阳系里的八大行星一样,在宇宙的绝大部分星系中都拥有数量众多的行星。一般来说,行星的表面温度要比主恒星的温度低,可偏偏就有一颗行星,温度比许多恒星都要高!俄亥俄州立大学的研究人员发现了一颗距离地球大约650光年的神秘星系,这个星系中的恒星叫KELT-9。这是一颗非常年轻的恒星,它的年纪只有3亿岁(太阳的年纪约45.7亿岁),但是它的质量却是太阳的3.5倍,表面温度也要比太阳高很多。我们要说的,正是距离它最近的行星——KELT-9b。
Just like the eight planets in our solar system, we have a large number of planets in most galaxies in the universe. In general, the planet’s surface temperature is lower than the temperature of the main star, but there is a planet, the temperature is higher than many stars! Researchers at Ohio State University discovered a mysterious galaxy about 650 light-years from Earth , The star in this galaxy is KELT-9. This is a very young star, it is only 300 million years old (about 4.57 billion years old sun), but its quality is 3.5 times the sun, the surface temperature is much higher than the sun. What we are going to say is precisely the planet closest to it, KELT-9b.
