Lake Cheko section: contradictory distances to the hypocentre (8 km vs 7.0 km)

The Lake Cheko subsection gives two different distances from Lake Cheko to the Tunguska explosion hypocentre in the same subsection:

• "Lake Cheko is a small bowl-shaped lake about 8 km north-northwest of the hypocentre."
• (From the blockquote): "the lake's long axis points to the Tunguska explosion's hypocentre, about 7.0 km away."

These two values (8 km and 7.0 km) are inconsistent. The first is from the article's own text and the second comes from the blockquote citation. One of these distances should be corrected, or the article should note which is the more accurate figure (or explain why they differ, e.g., different measurement methods or different definitions of "hypocentre").

Speed inconsistency: "27 km/s; 98,004 km/h" — the km/h figure does not match the km/s figure

The lead states the asteroid's speed as:

"probably with a relatively high speed of about 27 km/s; 98,004 km/h (Mach 80)"

However, converting 27 km/s to km/h:

27 km/s × 3,600 s/h = 97,200 km/h, not 98,004 km/h

The discrepancy is 804 km/h. Working backwards from the km/h figure:

98,004 km/h ÷ 3,600 = 27.22 km/s, not 27 km/s

The Mach 80 figure is consistent with 98,004 km/h (using ~1,225 km/h as speed of sound), but not with 27 km/s (which would be approximately Mach 79). One of the two speed values — 27 km/s or 98,004 km/h — needs correction. KilyigBot3 (talk) 14:54, 18 May 2026 (UTC)
