Leonid meteor hunting can be incredible, or a total bust. The radiant point of meteor showers is fixed. Usually, meteor showers get their names from Comet Swift-Tuttle was discovered in 1862 by Lewis Swift and Horace Tuttle. Meteor shower viewing conditions are strongly affected by the moon phase at the time of the shower, with a bright Full Moon causing the most disturbance, washing out fainter meteors. Marcy remains active in her astronomy club including being the editor of a monthly newsletter. Often, youll hear astronomers speak of a meteor showers radiant point. The debris that causes the shower is linked to the asteroid 3200 Phaethon, which measures about 3 miles across. duration depends on how wide the dust trail is; some are narrow,
You might be asking: Why hasnt anyone told me this before? The Geminids meteor shower, which peaks during mid-December each year, is considered to be one of the best and most reliable annual meteor showers.

For example, it sometimes appears to eject dust when it nears the sunas is common with comets. 15 and May 27 and peaks on May 5-6. This strong shower is produced by Comet 109P/Swift-Tuttle, an icy body that takes 133 Earth years to orbit once around the sun. Fragments of the comet appear as bright spots within the dust trail. One of the best parts about the Geminid shower is that they will last for most of the night, so skygazers will have multiple opportunities to try and spot a shooting star. These meteors are also visible in the southern hemisphere, but at reduced rates. It overlaps with the more famous Perseid meteor shower, which rises slowly to its peak each year around August 11, 12 and 13. Comets are icy, dusty objects. With swift and bright meteors, Perseids frequently leave long "wakes" of light and color behind them as they streak through Earth's atmosphere. Sometimes meteor showers produce exceptionally bright streaks. There are two kinds of meteors sporadic meteors and shower meteors. Photographing a meteor shower can be an exercise in patience, but with these tips and some good fortune you might be rewarded with a great photo. Youll see lots more meteors that way! meteor shower.

The period of activity peaks on Oct. 20 but begins on Sept. 26 and lasts until Nov. 22. A This gas reflects radar waves and as a result the meteors can also be detected during the day. Meteors are space rocks that are as small as a They are active between Nov. 3 and Dec. 2 and will peak on Nov. 17-18. The Leonids' radiant is located in the sickle-shaped head of the constellation Leo, the lion.

The radiant in such cases is above the horizon at the meteor's altitude. During the active period of most showers, the radiant moves nearly one degree eastwards, parallel to the ecliptic, against the stellar background each day. The radiant is located between the end of the 'tail' in Ursa Major and the 'head' in Draco. Occasionally, this can produce outbursts or brief periods of intense activity in which skywatchers can see more than 1,000 meteors per hour. The great circles for meteors
