How big was the meteor that hit Siberia?

The researchers estimated that the Tunguska meteor likely measured between 328 and 656 feet (100 and 200 m) in diameter, and hurtled through Earth’s atmosphere at roughly 45,000 mph (72,000 km/h). During its fiery passage, the meteor would lose some of its mass.

What was the Tunguska object?

Tunguska explosion largest in recorded history This type of atmospheric explosion was still enough to cause massive damage to the forest in the region. Scientists determined the object was most likely a stony asteroid approximately the size of a 25-story building.

How high was the meteor that hit Earth in 2013?

On 1 March 2013 NASA published a detailed synopsis of the event, stating that at peak brightness (at 09:20:33 local time), the meteor was 23.3 km high, located at 54.8°N, 61.1°E. At that time it was travelling at about 18.6 kilometres per second (67,000 km/h; 42,000 mph) —almost 60 times the speed of sound.

How high did the Chelyabinsk meteor explode?

The object exploded in a meteor air burst over Chelyabinsk Oblast, at a height of around 29.7 km (18.5 mi; 97,000 ft). The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2 km (16.3 mi), and many surviving small fragmentary meteorites.

Bottom line: The Tunguska explosion on June 30, 1908, was the largest asteroid impact in recorded history. It flattened 830 square miles (2150 sq km) of Siberian forest.

What if the Tunguska meteor hit Moscow?

The Tunguska event was likely the equivalent of a nuclear bomb between 10 and 15 megatons in size. An explosion of such a size would easily be enough to destroy any of those cities circa 1908. (St. Petersburg, incidentally, should be included on that list, as it was capital of Russia at this time.

Did a meteor hit Russia?

The Chelyabinsk meteor struck without warning. Dmitry Medvedev, the Prime Minister of Russia, confirmed a meteor had struck Russia and said it proved that the “entire planet” is vulnerable to meteors and a spaceguard system is needed to protect the planet from similar objects in the future.

Where did the Tunguska explosion occur?

Tunguska event, enormous explosion that is estimated to have occurred at 7:14 am plus or minus one minute on June 30, 1908, at an altitude of 5–10 km (15,000–30,000 feet), flattening some 2,000 square km (500,000 acres) and charring more than 100 square km of pine forest near the Podkamennaya Tunguska River in central …

How big was the Russian meteor that hit Earth?

In a latest report on the Russian meteor, NASA said that the meteor was much larger than the initial estimate. “The estimated size of the object, prior to entering Earth’s atmosphere, has been revised upward from 49 feet (15 meters) to 55 feet (17 meters), and its estimated mass has increased from 7,000 to 10,000 tons,” NASA said.

What caused the Ural meteor that hit Russia?

It was caused by an approximately 20 m (66 ft) near-Earth asteroid with a speed relative to Earth of 19.16 ± 0.15 kilometres per second (60,000 –69,000 km/h or 40,000 –42,900 mph). It quickly became a brilliant superbolide meteor over the southern Ural region.

Where did the Tunguska meteor explode in 1908?

On June 30, 1908, says NASA, a truly massive meteor exploded near the Podkamennaya Tunguska River in Siberia.
