The International Meteor Organization (an amateur organization that studies meteors) has a more rigid definition. It defines a fireball as a meteor that would have a magnitude of −3 or brighter if seen at zenith. This definition corrects for the greater distance between an observer and a meteor near the horizon.
The Perseids are a prolific meteor shower associated with the comet Swift–Tuttle that are usually visible from mid-July to late-August.The meteors are called the Perseids because they appear from the general direction of the constellation Perseus and in more modern times have a radiant bordering on Cassiopeia and Camelopardalis.
The October Draconids, in the past also unofficially known as the Giacobinids, are a Northern hemisphere meteor shower whose parent body is the periodic comet 21P/Giacobini-Zinner. They are named after the constellation Draco, where they seemingly come from. Almost all meteors which fall towards Earth ablate long before reaching its surface ...
The Leonids are famous because their meteor showers, or storms, can be among the most spectacular. Because of the storm of 1833 and the developments in scientific thought of the time (see for example the identification of Halley's Comet), the Leonids have had a major effect on the scientific study of meteors, which had previously been thought to be atmospheric phenomena.
The Taurids are an annual meteor shower, associated with the comet Encke.The Taurids are actually two separate showers, with a Southern and a Northern component. The Southern Taurids originated from Comet Encke, while the Northern Taurids originated from the asteroid 2004 TG 10, possibly a large fragment of Encke due to its similar orbital parameters.
The Muonionalusta meteorite (Finnish pronunciation: [ˈmuo̯nionˌɑlustɑ], Swedish pronunciation: [mʉˈǒːnɪɔnalːɵsta]) [1] is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.
The Quadrantids (QUA) are a meteor shower that peaks in early January and whose radiant lies in the constellation Boötes.The zenithal hourly rate (ZHR) of this shower can be as high as that of two other reliably rich meteor showers, the Perseids in August and the Geminids in December, [4] yet Quadrantid meteors are not seen as often as those of the two other showers because the time frame of ...
The Arietids, along with the Zeta Perseids, are the most intense daylight meteor showers of the year. [3] The source of the shower is unknown, but scientists suspect that they come from the asteroid 1566 Icarus , [ 3 ] [ 4 ] although the orbit also corresponds similarly to 96P/Machholz .
