科学家发现一个水星大小的行星由于恒星附近的极端热度而迅速解体。 Astronomers discover a Mercury-sized planet disintegrating due to extreme heat from its star.

天文学家发现了一个小的岩石行星,BD+05 4868 Ab,距离约140光年,由于围绕其恒星的近轨道,该行星迅速解体。 Astronomers have found a small, rocky planet, BD+05 4868 Ab, about 140 light-years away, rapidly disintegrating due to its close orbit around its star. 行星的体积与水星类似,在30.5小时内完成轨道,导致地表温度超过3000华氏度,使地球抛落的材料相当于每个轨道一个珠穆朗玛峰。 Similar in size to Mercury, the planet completes an orbit in 30.5 hours, leading to surface temperatures over 3,000 degrees Fahrenheit and causing it to shed material equivalent to one Mount Everest each orbit. 预计这一解体将在100万至200万年后完全摧毁地球。 This disintegration is expected to completely destroy the planet in 1 to 2 million years.
