In the dark morning hours of January 18, 2000, a fireball exploded over the city of Whitehorse, Yukon Territory at an altitude of about 26 km (16 mi), lighting up the night like day. The meteor that produced the fireball was estimated to be about 4.6 m (15 ft) in diameter, with a weight of 180 tonnes.
For these reasons Jupiter has the highest frequency of impacts of any planet in the Solar System, justifying its reputation as the "sweeper" or "cosmic vacuum cleaner" of the Solar System. [7] 2018 studies estimate that between 10 and 65 impacts per year of meteoroids with a diameter of between 5 and 20 meters (16 and 66 ft) can occur on the ...
Meteoroids moving through Earth's orbital space average about 20 km/s (45,000 mph), [20] but due to Earth's gravity meteors such as the Phoenicids can make atmospheric entry at as slow as about 11 km/s. On January 17, 2013, at 05:21 PST, a one-meter-sized comet from the Oort cloud entered Earth atmosphere over California and Nevada. [21]
Most years, including this year, the Leonids bring around 15 shooting stars per hour, but on rare occasions, it has erupted into an all-out meteor storm with thousands of meteors per hour.
In most years, the most visible meteor shower is the Perseids, which peak on 12 August of each year at over one meteor per minute. NASA has a tool to calculate how many meteors per hour are visible from one's observing location. The Leonid meteor shower peaks around 17 November of each year. The Leonid shower produces a meteor storm, peaking at ...
Most meteor showers feature meteoroids that are only millimeters in length, Cooke said, but the Taurids can have meteoroids up to an impressive 1 meter (3 feet) long, making them appear very ...
The Perseids can produce about one to two meteors per minute or between 50 to 100 per hour, according to NASA. But you can only catch a show like that under ideal viewing conditions.
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
