On October 4, 2017 around 8:07 PM local time, an extremely bright [[meteoroid]] fell over the northern [[Yunnan]] province of China, reaching maximum [[brightness]] roughly {{convert|37|km|mi|abbr=off}} above the ground.<ref name=jpl/> The 8-second [[superbolide]] was widely recorded, as it fell in the late evening on the [[Mid-Autumn Festival]], a fairly popular festival in China.<ref name="natgeoreport">{{cite news|title=Surprise Meteor Lights Up Harvest Moon Festival|url=https://news.nationalgeographic.com/2017/10/full-moon-meteor-fireball-china-space-science/|archive-url=https://web.archive.org/web/20171010061317/http://news.nationalgeographic.com/2017/10/full-moon-meteor-fireball-china-space-science/|url-status=dead|archive-date=October 10, 2017|accessdate=5 December 2017|publisher=National Geographic|date=9 October 2017}}</ref>

==Overview==
Based on its incoming velocity of {{convert|14.6|km/s|mph|abbr=on}} and energy, the original asteroid was likely between {{convert|2.2|and|3.6|m|ft|abbr=off}} across,<ref name="impactcalculator">{{cite web|title=Asteroid Impact Crater Calculator - calculates the effects of the impact of an object hitting the earth|url=http://convertalot.com/asteroid_impact_calculator.html|website=convertalot.com|accessdate=5 December 2017}}</ref> slightly smaller than the [[2015 Thailand bolide]], which fell about 2 years previously, several hundred miles to the south.

This is the largest recorded meteor to fall over China since the 2000 bolide, which radiated about {{convert|262|GJ|lk=in}} of energy compared to the 2017 event's {{convert|192|GJ}}. While it was only the 5th most energetic impact event of 2017, it was the largest one to occur over land, and a populated area no less.<ref name="jpl"/>
