Impactor’s estimated velocity: 12.6-73km/s (4,500-26,000km/hr or 2,800-16,300mph) Impactor’s estimated diameter: 9-11km (~5.5-6.8mi) up to 81km (50mi) Impactor’s estimated mass: 0x1015-4.6×1017kg  (2.2×1015-1.0×1018lb)

The generally held view is that the impactor was an asteroid about 10km (6mi) in diameter, traveling at 16-32 km/sec (10-20 miles/sec, o...
