The meteor material intersects the earthвЂ™s orbit on its inbound leg, and the earth arrives at this location every mid-December, hence the Geminids meteor shower. Then it scoots out past the orbit of Mars. It is still not known how material from the asteroidвЂ™s surface, or interior, is released into the meteoroid stream.ДЈ200 Phaethon gets very close to the sun, half the distance as is the innermost planet, Mercury. This was very unusual, as never before had an asteroid been suggested as causing a meteor shower. As the orbit was calculated, Fred Whipple announced that this asteroid has the same orbit as the Geminids meteor shower. Initially named 1983 TB, it was given an asteroid name: 3200 Phaethon in 1985. The asteroid 3200 Phaethon seems to be an example of either a dormant or an extinct comet.ДЈ200 Phaethon was discovered on images taken by IRAS (Infrared Astronomical Satellite) on Octoby Simon Green and John Davies. When the comet loses all of its volatile materials, it is known as an extinct comet. It is possible that a comet can shut down when its volatile materials become trapped beneath the nucleusвЂ™ surface. Can the opposite occur: a comet be reclassified as an asteroid? Yes, it can. So, an object initially considered an asteroid can be reclassified as a comet. It orbits the sun every 50 years and travels from just inside the orbit of Saturn to the orbit of Uranus. An odd object named Chiron, considered an asteroid when discovered in 1977, was reclassified as a comet in 1989 when it showed a coma. Larger telescopes began discovering asteroids far from the sun, and some of these objects, as they approached the sun, grew comas and tails, requiring the change of designation from asteroid to comet. These definitions worked well until a few decades ago. Through a telescope an asteroid appears star-like. Typically, an asteroidвЂ™s orbit is more circular than that of a comet. But when seen far from the sun, most comets appear star-like, because only the nucleus is observed.ДЄn asteroid is a rock.

Seen through a telescope, a comet will show a coma, or head of the comet, as a nebulous patch of light around the nucleus, when it gets close to the sun. They revolve around the sun in elongated orbits, going close to the sun, then going far from the sun. Comets are typically lightweight, with a density slightly heavier than water. WhatвЂ™s the difference between a comet and an asteroid?ДЄ comet is defined as a dirty snowball, with a solid nucleus covered by a layer of ice which sublimates (turns from a solid to a gas) as the comet nears the sun. This differs from most meteor showers which are caused by comets, not asteroids. Geminid meteor shower parent cometДЇrom Don Machholz, who has discovered 12 comets вЂ¦ An asteroid known as 3200 Phaethon is responsible for the Geminids meteor shower. In 2022, a waning gibbous will wash out the meteors during the peak. local time (time on your clock for all parts of the globe). The meteors radiate from near the bright star Castor in the constellation Gemini, in the east on December evenings, highest around 2 a.m. Report a fireball (very bright meteor) to the American Meteor Society: itвЂ™s fun and easy! Watch the Geminid meteor shower this week. The meteors are plentiful, rivaling the August Perseids. TheyвЂ™re also visible, at lower rates, from the Southern Hemisphere. Note: The bold, white, bright Geminids give us one of the Northern HemisphereвЂ™s best showers, in years when thereвЂ™s no moon. So itвЂ™s a bright waning gibbous moon thatвЂ™ll illuminate the sky during the 2022 Geminid meteor peak.Д®xpected meteors at peak, under ideal conditions: Under a dark sky with no moon, you might catch 120 Geminid meteors per hour. Nearest moon phase: In 2022, last quarter moon falls on December 16.

Radiant: Rises in mid-evening, highest around 2 a.m. Overall duration of shower: November 19 to December 24. One option is to try watching in moonlight on the nights of December 13 and 14. The moon will rise slightly later on December 14. When to watch: The moon will illuminate the sky from late evening on, on the evening of December 13.

Predicted peak: is predicted* for December 14, 2022, at 13 UTC.
