   Meteor shower (Wikipedia)

   WikipediaPublished Oct 16, 2026Checked Oct 18, 2026

   “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. Historically, meteor showers were regarded as an atmospheric phenomenon. In 1794, Ernst Chladni proposed that meteors originated in outer space. The Great Meteor Storm of 1833 led Denison Olmsted to show it arrived as a cloud of space dust, with the streaks forming a radiant point in the direction of the constellation of Leo.”

   Activity of the Eta-Aquariid and Orionid meteor showers

   Astronomy and Astrophysics (Egal et al.)Published Jun 16, 2020Checked Oct 18, 2026

   “These techniques probe the range of meteoroid masses from submilligrams to grams. Theη-Aquariids and Orionids activity duration, shape, maximum zenithal hourly rates values, and the solar longitude of annual peaks since 1985 are analyzed. When available, annual activity profiles recorded by each detection network were measured and are compared. Results.Observations from the three detection methods show generally good agreement in the showers’ shape, activity levels, and annual intensity variations. Both showers display several activity peaks of variable location and strength with time. Theη-Aquariids are usually two to three times stronger than the Orionids, but the two showers display occasional outbursts with peaks two to four times their usual activity level. CMOR observations since 2002 seem to support the existence of an ~12 yr cycle in Orionids activity variations; however, additional and longer term radar and optical observations of the shower are required to confirm such periodicity.”

   Comets and Meteor Showers

   Research paper (Ye & Jenniskens)Published Jan 1, 2024Checked Oct 18, 2026

   “Earth occasionally crosses the debris streams produced by comets and other active bodies in our solar system. These manifest meteor showers that provide an opportunity to explore these bodies without a need to visit them in-situ. Observations of meteor showers provide unique insights into the physical and dynamical properties of their parent bodies, as well as into the compositions and the structure of near-surface dust. In this chapter, we discuss the development and current state of affairs of meteor science, with a focus on its role as a tool to study comets, and review the established parent body -- meteor shower linkages.”

   Activity of the Leonid meteor shower on 2009 November 17

   “Context. The double-station video experiment was established in Tajikistan to confirm the prediction of the Leonid meteor shower in 2009 activity connected with the material that was ejected from the parent comet in 1466 and 1533.”

   Leonid Meteor Observer in LEO: A University Microsatellite to Observe a Meteor Shower from Space

   Digital Commons - USU (Utah State University) (Yoshida et al.)Published Jan 1, 2000Checked Oct 18, 2026

   “This paper presents university-based design and development of a micro-satellite for the observation of a meteor shower from the low Earth orbit. The satellite will be launched as a piggy-back payload of a commercial rocket launcher, a few weeks before the 2001 or 2002 Leonid meteor maximum in which thousands of meteors are scienti_cally expected. The goal of the mission is to conduct the scienti_c observation of the prospective meteor outburst from out of atmosphere, counting the meteors in the large coverage of the night sky looked down on Earth and obtaining visible-Ultra Violet spectrographs of the meteor. Possible launch opportunity remains to be seen, but the designs of the satellite bus and scientific payloads are now initiated.”
