A luminous, unidentified flying object emitting a brilliant green light, streaked across the night sky in southern China.

The video was filmed in the city of Chengdu in Sichuan Province on June 22.

Zeng Yang, Vice President of the Sichuan Astronomical Science Popularization Association, said the object was highly likely to be a bolide.

Bodies from the solar system burn brightly when they enter the Earth's atmosphere. These fireballs are typically larger and faster than standard meteors, resulting in a more intense luminescence during their transit.

These meteors often take on a green hue, a common characteristic of bolides. This occurs when iron meteorites, containing the element magnesium, combust upon entering the Earth's atmosphere. If any parts of the meteor survive the descent and land on Earth, they are referred to as meteorites.

6月22日晚，四川成都多地居民，看到一个发出闪亮绿光的不明飞行物从夜空划过。
对此，四川省天文科普学会副会长曾阳表示，大概率为火流星，火流星实际上是进入大气层后的太阳系小天体，由于体积较大且运行速度较快，因此过程中的发光强度也相对于普通流星来说也更大一些。在天文学上也被称为陨星，落在地面的物质，则是我们常说的陨石。发绿光的是最常见的一种火流星，一般是铁陨石含镁元素燃烧产生这种绿色火光。
