with a rate of 120meteorsper hour during its peak,according to NASA. The shower occurs between Nov. 19 and Dec. 24 with a peak around Dec. 14. Though the shower originates from the debris trail of asteroid3200 Phaethon, its radiant point (that is, the point from which the meteors appe...
By subjecting meteors to radiometric dating, we know that the sun and Earth are around 4.6 billion years old. When similar radiometric dating techniques are applied to rocks brought back from the moon landings, the oldest rocks are found to be 4.46 billion years old, meaning that the moon is...

The population index of the Ursids meteor shower is 3. The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are. For this particular meteor shower, bright meteors are more frequent....
The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are. For this particular meteor shower, faint meteors are more frequent.
Only 12 Martian meteors are known to exist on earth and are collectively called Shergotty-Nakhla-Chassingy or SNC (“snick”) meteorites. The most famous one is called Allan Hills (ALH) 84001 and is believed to have blasted off Mars 16 million years ago, hitting Earth 13,000 years ago ...
