Near misses like this must have been remarkably common for the Earth over millions of years. State the obvious mode-it was recorded on the same day! August 10th, 1972, recorded in Alberta of Canada. So to have someone with one around to observe the fireball, and to film it so steadily as it erupted into view, is a stroke of most excellent good fortune.Īmazingly, there’s also a second recording of the event. In the early ’70s, home video cameras were still pretty rare. The fact it’s saved for posterity is rather lucky. It is thought the #asteroid had a diameter of ~10m.
The #GreatDaylightFireball☄️entered Earth’s atmosphere at a very shallow angle and didn’t lose sufficient energy to be captured by Earth’s gravity and fall to the ground. More recently, as in the 10th August 2022, various space agencies marked the 50th anniversary since it hurtled through the sky. The documentary had been updated from an episode in the early 1990s. In 1999, we watched a BBC Horizon documentary called New Asteroid Danger (you can watch it on that link, if you wish) that brought our attention to this thing. And many who observed it reported a considerable double sonic boom as it stormed along at 15 kilometres per second. It came within 57 kilometres (35 miles, which is 187,000 feet) of striking the Earth. It blasted into the atmosphere above Utah around 2:30pm. The meteor was an Earth-grazing fireball. A lady called Linda Baker filmed the meteorite in amateur footage later praised for providing key insights into its trajectory, velocity, and psycho rating.
