List Of Meteor Showers
Named meteor showers recur at approximately the same dates each year. They appear to radiate from a certain point in the sky, known as the radiant, and vary in the speed, frequency and brightness of the meteors. As of November 2019, there are 112 established meteor showers. Table of meteor showers Dates are given for 2022.https://www.amsmeteors.org/meteor-showers/2020-meteor-shower-list/ 2022 IMO list at amsmeteors.org The dates will vary from year to year due to the leap year cycle. This list includes showers with radiants in both the northern and southern hemispheres. There is some overlap, but generally showers whose radiants have positive declinations are best seen from the northern hemisphere, and those with negative declinations are best observed from the southern hemisphere.

Meteor Shower
A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface. Very intense or unusual meteor showers are known as meteor outbursts and meteor storms, which produce at least 1,000 meteors an hour, most notably from the Leonids. The Meteor Data Centre lists over 900 suspected meteor showers of which about 100 are well established. Several organizations point to viewing opportunities on the Internet. NASA maintains a daily map of active meteor showers.

Comet IRAS–Araki–Alcock
Comet IRAS–Araki–Alcock (formal designation C/1983 H1, formerly 1983 VII) is a long-period comet that, in 1983, made the closest known approach to Earth of any comet in 200 years, at a distance of about . The comet was named after its discoverers the Infrared Astronomical Satellite and two amateur astronomers, George Alcock of the United Kingdom and Genichi Araki of Japan. Both men were schoolteachers by profession, although Alcock was retired. Alcock had made his discovery simply by observing through the window of his home, using binoculars."Obituary of George Alcock" , 21 December 2000.

Aurigids
Aurigids is a meteor shower occurring primarily within September. The comet Kiess (C/1911 N1) is the source of the material that causes the meteors. The comet's orbital period is stated as approximately 1800 to 2000 years, with showers observed in the years 1935, '86, '94 and 2007 . α & δ The Alpha were discovered by C. Hoffmeister and A. Teichgraeber, during the night of 31 August 1935. See also * Carl Clarence Kiess * Delta Aurigids * List of meteor showers Named meteor showers recur at approximately the same dates each year.

Kappa Cygnids
Kappa Cygnids, abbreviated KCG and IAU shower number 12, was an episodic meteor shower that took place from June to September, peaking around August 13, along with the larger Perseids meteor shower. The radiant of the shower emerged from the antihelion source in late June and moves upwards to Cygnus in July. In early August, the radiant is just west of the star Vega and elongated in a north-south direction. The shower then turns a corner and moves to the east in late August. The Kappa Cygnids are named for the position of the radiant at the peak of the shower, where the meteor shower will appear to line up in sky by the constellation Cygnus and the star Kappa Cygni Kappa Cygni, Latinized from κ Cygni, is a star in the northern constellation of Cygnus. It has an apparent visual magnitude of 3.8, which is bright enough to be seen with the naked eye. In the constellation, it forms the tip of Cygnu ....

109P/Swift-Tuttle
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perseids
The Perseids are a prolific meteor shower associated with the comet Swift–Tuttle. The meteors are called the Perseids because the point from which they appear to hail (called the radiant) lies in the constellation Perseus. Etymology The name is derived from the word Perseidai ( el, Περσείδαι), the sons of Perseus in Greek mythology. Characteristics The stream of debris is called the Perseid cloud and stretches along the orbit of the comet Swift–Tuttle. The cloud consists of particles ejected by the comet as it travels on its 133-year orbit. Most of the particles have been part of the cloud for around a thousand years. However, there is also a relatively young filament of dust in the stream that was pulled off the comet in 1865, which can give an early mini-peak the day before the maximum shower. The dimensions of the cloud in the vicinity of the Earth are estimated to be approximately 0.1 astronomical units (AU) across and 0.8 AU along the Earth's orbit, spre ...

169P/NEAT
169/NEAT is a periodic comet in the Solar System. It is the parent body of the alpha Capricornids meteor shower in Late July. 169/NEAT may be related to comet P/2003 T12 (SOHO). It comes to perihelion (closest approach to the Sun) on 9 July 2022. On 13 July 2022 passed from Venus. On 11 August 2026 it will pass from Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water.

Alpha Capricornids
Alpha Capricornids is a meteor shower that takes place as early as 7 July and continues until around 15 August. The meteor shower was discovered by Hungarian astronomer Miklos von Konkoly-Thege in 1871. This shower has infrequent but relatively bright meteors, with some fireballs. Parent body is comet 169P/NEAT. Peter Jenniskens and Jeremie Vaubaillon identified the parent body as asteroid 2002 EX12, which in the return of 2005 was found weakly active near perihelion. This object is now called comet 169P/NEAT. According to Jenniskens and Vaubaillon, the meteor shower was created about 3,500 to 5,000 years ago, when about half of the parent body disintegrated and fell into dust. The dust cloud evolved into Earth's orbit Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes days (1 sidereal year), during which time Earth ... recently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Delta Aquariids
The Southern Delta Aquariids are a meteor shower visible from mid July to mid August each year with peak activity on 28 or 29 July. The Comet of origin is not known with certainty. Suspected candidate is Comet 96P Machholz. Earlier, it was thought to have originated from the Marsden and Kracht Sungrazing comets. The Delta Aquariids get their name because their radiant appears to lie in the constellation Aquarius, near one of the constellation's brightest stars, Delta Aquarii. The name derives from the Latin possessive form "Aquarii", whereby the declension "-i" is replaced by "-ids" (hence Aquariids with two i's). There are two branches of the Delta Aquariid meteor shower, Southern and Northern. The Southern Delta Aquariids are considered a strong shower, with an average meteor observation rate of 15–20 per hour, and a peak zenith hourly rate of 18. The average radiant is at RA=339°, DEC=−17°. The Northern Delta Aquariids are a weaker shower, peaking later in mid Augus ...

June Bootids
The June Boötids are a meteor shower occurring roughly between 22 June and 2 July each year. In most years their activity is weak, with a zenith hourly rate (ZHR) of only 1 or 2. However, occasional outbursts have been seen, with the outburst of 1916 drawing attention to the previously unrecorded meteor shower. The most recent outburst occurred in 1998, when the ZHR reached up to 100. The meteor shower occurs when the Earth crosses the orbit of Comet Pons-Winnecke, a short-period comet which orbits the Sun The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radi ... once every 6.37 years. They can be very unpredictable. They are also considered very slow meteors, as there are much faster ones. They peak on June 27. External links * http://meteorshowersonline.com/showers/june_bootids.h ...

1566 Icarus
1566 Icarus ( ; ''provisional designation'': ) is a large near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. It has is an extremely eccentric orbit (0.83) and measures approximately in diameter. In 1968, it became the first asteroid ever observed by radar. Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crossing asteroid. This stony asteroid and relatively fast rotator with a period of 2.27 hours was discovered on 27 June 1949, by German astronomer Walter Baade at the Palomar Observatory in California. It was named after the mythological Icarus. Orbit and classification Icarus orbits the Sun at a distance of 0.19–1.97 AU once every 13 months (409 days; semi-major axis of 1.08 AU). Its orbit has an eccentricity of 0.83 and an inclination of 23 ° with respect to the ecliptic. The body's observation arc begins with its official ...
