Video argues a Taurid origin for Tunguska; the link remains debated

▶

Key facts

• The Tunguska airburst occurred at about 7:14 a.m. local time on June 30, 1908, in Central Siberia. The United Nations designated June 30 as Asteroid Day in 2017.
• The incoming object's size is estimated at roughly 50–70 metres (165–230 feet); the airburst energy is generally estimated at 10–15 megatons TNT.
• The February 15, 2013 Chelyabinsk meteor was about 20 metres (66 feet) across and injured roughly 1,500 people.
• The video presents a reconstruction of eyewitness bearings at points A, K and Z and argues that it places Tunguska's radiant near the Taurid stream. This interpretation is disputed, not an established cause.
• The Taurid complex includes the beta Taurid branch. Geographos, Icarus and Adonis are Apollo-class asteroids with semimajor axes of about 1.25, 1.08 and 1.87 AU, respectively—not all around 2.2 AU—and their assignment to the Taurid complex is not established.
• Apollo-era lunar seismometers recorded a large meteoroid impact swarm in 1975. The video connects its timing with the Taurid stream, but that identification does not establish the swarm's source.
• The video invokes a proposed giant parent comet, potentially about 80 kilometres (50 miles) across and hundreds of times Halley's volume, placed on a sub-Jovian orbit 25,000–30,000 years ago. This is a model hypothesis.
