Are meteor showers a result of collision of asteroids?
No. The meteors you see in meteor showers are sand to pebble sized objects that burn up long before reaching the ground. Most meteors are too small to reach the surface. Meteorites come from larger meteors that fall individually and often show up brilliantly in the night sky. Some a bright enough to be visible during the day.
What celestial objects can a meteoroid come from?
Most of the space rocks which eventually become meteoroids formed in space about the same time as the rest of the solar system did. Probably the most common meteoroids are remnants of comets; we know that several of the annual "meteor showers" are associated with known cometary orbits. Many meteoroids were fragments broken from asteroids when they have collided. And at least a couple of meteorites which have been discovered here on Earth are known to have come from Mars! Asteroid impacts on Mars have knocked rocks and dust completely off of Mars and into orbit around the Sun, where they have impacted the Earth.
What meteor can be seen without a telescope?
Sometimes when you look up at the sky you'll see a meteor, by chance. You can't know in advance when you'll see one, and they only last a fraction of a second or a few seconds at most - but at some times of the year there are more than at others (the so-called meteor showers).
When a comet breaks apart can a dust cloud form a meteoroid?
Yes. Old and extinct comets are probably the source of most of the "meteor showers" that we see over the year. It's not that the dust forms something else; the dust ARE the meteoroids.
What shape are most planets' orbits around the sun in specific the earth?
ALL planetary orbits are ellipses.
What do meteor showers occur from?
We believe that most meteor showers are caused by decaying comets shedding dust and rocks in their wake as they travel through the solar system.
Which two planets are most of the meteor showers in?
On Earth meteor showers occur when we pass through dirt in space, usually from the debris or remains of a comet's tail. Any planet that passes through a dirty part of space and then has that dirt burn out above it will be a place that you can see meteor showers.
How did leonids get their name?
The Leonid meteor showers are so named because they appear to radiate from near the constellation Leo in the night sky. Most of the periodic meteor showers are named based on the area of the sky from which they appear.

What country could the geminid meteor shower be seen?
Most meteor showers are visible all around the world. Meteor showers occur when the Earth passes through the debris stream left behind from a comet; some comet trails are better mapped than others, and in some cases astronomers are able to predict with some accuracy exactly when the Earth will pass through the stream.Meteors are most commonly observed between midnight and dawn, when the "front" of the Earth passes through.
What causes meteor?
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. Intense or unusual meteor showers are known as meteor outbursts and meteor storms, which may produce greater than 1,000 meteors an hour.[1]The Meteor Data Center lists about 600 suspected meteor showers of which about 100 are well established.[2]
How are annual meteor showers affected by cometary orbits?
As comets whiz by the Sun in each orbit, they melt a little, shedding dust and pebbles which are pulled away as part of the comet's tail. After several thousand passes, there's a thin cloud of dust and pebbles throughout the entire orbital path of the comet. If the Earth goes through the comet's path (even when the comet is nowhere close, and especially if the comet disintegrated centuries ago), we see a "meteor shower" of dust and tiny pebbles. The most common meteor shower is the Perseids, which peak around August 13, but they're visible a week before and after.
When will the Perseid meteor shower be visible in Israel 2010?
The peak time will be the night of Thursday, August 12 and the early morning of Friday, August 13. Starting about 3 days ago, for another 6 or 7 days. The best time is from about 2 AM to dawn. For most meteor showers, it doesn't matter where you are; from 2AM to dawn.

Most of the space rocks which eventually become meteoroids formed in space about the same time as the rest of the solar system did.

What are the most easily seen meteor showers from earth and when can they be seen?
Probably the best are the Perseids, which occur in August. Every 33 years, the Leonids of November are potentially great, although 1999 was a disappointment. In general, all showers are best seen after midnight, when the Earth is turned "forward" in its orbit and is therefore "heading into" the debris field of the meteoroids.
