What is a Shooting Star?

A shooting star is not actually a star, nor does it shoot. It is officially called a meteor, a chunk of extraterrestrial rock pulled into the Earth's atmosphere by gravity. Most meteors are closer to dust or sand in size, not the large boulders frequently seen in science fiction movies. As these tiny fragments of rock fall through the Earth's outer layers of air, they experience a build-up of frictional heat, which causes the individual particles glow brightly as they continue to fall and burn up. Observers on the ground may catch a fleeting glimpse of one as it streaks across the night sky.

It is easy to see how the shooting star earned its nickname. People are accustomed to seeing fixed points of light in the night sky, commonly known as stars and planets. What they're not so accustomed to is observing one of these points of light falling out of place or suddenly burning out. When someone sees a meteor heat up and streak across the sky, it often looks like a real star dropping out of the sky. A particularly large meteor may continue to glow for several seconds, appearing to shoot across the sky under its own power. Therefore, the idea of a shooting star has become a popular shorthand to describe the phenomenon.

Meteorologists can usually predict and suggest peak hours for viewing a meteor shower.

While a meteor may not be an actual star, it is definitely from outer space. The universe may look empty, but in actuality, it contains significant amounts of dust and rocks. When comets approach stars, for example, the heat of the star often causes a trail of space dust. If the Earth passes through one of these trails, the result can be a meteor shower or even a meteor storm. Instead of seeing an occasional shooting star, a viewer on Earth can expect to see dozens or even hundreds in a few hours' time.

Some of these meteor showers, such as the Perseids and Leonids, occur on a regular basis, so those interested in viewing them should find a clear field away from city lights during these events. A meteor can be seen with the naked eye, although it requires constant scanning of the night sky and a little luck, since the light can appear suddenly and burn out quickly. Local astronomers or meteorologists should be able to provide a peak time for maximum activity during a meteor shower.

Last night my younger brother and I saw a yellow streak of light move across the night sky. It was 11 p.m. in Vellore, some 130 kms east of Chennai. It looked a bit unusual to us, because shooting stars move fast and leave a silvery streak of light. Could you explain this please?


Three days ago, I saw a strange shooting star. It was midway between the clouds and earth. It crossed the sky horizontally in about two seconds. The strange thing is that I saw an opaque white sphere appearing from the disappearing trail. Then the sphere continued on its way until vanishing in some sort of smoke.

Please,has anybody seen that before and especially is there an explanation for that? Thanks!


When people think of a shooting star or a meteor shower, they think that it's a bunch of rocks falling onto earth. But these pieces are really small. They're not really rocks, more like rock dust.

This dust falls off of meteors in outer space and then gets caught up in our atmosphere an starts falling. It falls so fast that it burns up and dissolves before it hits the ground. That burning up is the trail of light we see when a star is "shooting."

@Madddoggg23-- Yes, they can. In fact, the annual meteor showers were first seen in Asia thousands of years ago. Historians have found mentions of it in artifacts.

My teacher has spent time on the desert and says that stars and shooting stars are more visible in the desert. I guess meteors fall more often than we realize, but it's harder to see them because there is too much man-made light around us.

I've seen a shooting star several times in the past. It wasn't as impressive as I thought it would be. I really want to go to the desert one day and see a shooting star there at night.


Can somebody help me please? I found a shooting star and it's about the size of a golf ball and I don't know how much it's worth, but I want to know. I'm in need of the money.


I think it would be so fun to go meteorite hunting. However, I've heard that a lot of shooting stars that actually make it all the way to Earth land in either the ocean or a desert. The western United States are supposedly full of them.

I have read that meteorites are either brown or black, and they appear silver on the inside. I've also read that you can find them with a metal detector.

They are worth a lot of money. If you do find one, in order to get it positively identified, you will have to give about twenty percent of its worth to the inspector.


I'm blessed enough to live out in the country, away from the lights of the city. I don't even have a street light near my yard, so on a clear night, I can see a sky littered with stars in great detail.

I like to watch the meteor shower that occurs in August. The best time to see the shooting stars is really late, like after 2 a.m. It can be hard to stay up that late at times, but it is worth it.

I saw so many shooting stars one year that I could not look at all of them at once. They were coming from several directions. It was truly a magical, extra-terrestrial feeling.


@shell4life – They can be different colors. I guess it depends on the atmosphere and how far away from Earth they are, but I have seen several different colors of shooting stars.

I saw a shooting star at a lodge where I was vacationing, and it was the most spectacular I have ever witnessed. It was bright green, and it seemed to be coming right toward me!

It was also the hugest I've ever seen. Normally, if they are far away, they will just leave white or pale yellow streaks of light. I've seen some that appeared orange, but the green one was definitely the closest!


I'm frustrated that I'm the only one of my friends who has never seen a shooting star! I have heard descriptions of them, but that isn't enough for me.

What color is the streak that a meteor makes? Is it always one color, or can it vary?


So can these annual meteor showers be seen all around the world?


Just so you know, all of the ones that I listed are meteor showers. Annually, you are likely to see a great number of meteors in the night sky. These meteor showers happen when the Earth passes through the trail of debris that a comet leaves behind while orbiting the Sun.


@snowywinter: That’s a good question. According to the research that I have done on them, I believe there are 9 that happen annually. I will list them in the order in which they occur.

The Quadrantids occur between January 1st and 6th. April Lyrids occurs between April 19th and 24th. Eta Aquarids occurs between May 1st and 8th. Delta Aquarids occurs between July 15th and August 15th. Perseids occurs between July 25th and August 18th. Orionids occurs between October 16th and 27th. Taurids occurs between October 20th and November 30th. Leonids occurs between November 15th and 20th. Geminids occurs between December 7th and 15th.


How many of these "shooting stars" occur regularly? I saw in the article that the Perseids and Leonids are regular but I was wondering if those were the only ones. Great article.


i have taken picture of a massive light on its own and zoomed in. it is a blob with shapes around it. very unusual. It was 4a.m in the morning and so clear to see could you explain please.
