Hey welcome to latest post that is “interesting facts about comets for kids“
Do you know what is this comet
Hey don’t tell. because if you will tell then, what I will do?
Comet is a small chunk made from material like dust and ice that travels around the sun or orbits.
It’s sometimes also called dirty snowball there are millions of like this in our solar system. As we know that planets revolve in a circular path but comets have their own way they revolve in a shape like an oval.The most known comet is Halley’s Comet. We will also see it.
There is too many things that we will see in this article they will really be very interesting so let’s get started

Do you know where this word “comet” came from? Obviously not with a comet.
This word comes from the Greek word that means ‘hair of the head’, it came from the Greek philosopher named Aristotle who observed comets as stars with long hair.
For much of human history, comets were not welcome as very good things but they were thought to symbolize disaster and doom.
Scientists think that comets were leftovers from the early development of our solar system about 4.6 billion years ago.
There are 4,595 only known comets in our solar system in 2021. Because there are billions in our solar system.
Comets sometimes can hit our Earth, but this sometime happened about 28 millions years ago.
The first comet to be observed in around 500 B.C. by a Greek philosophers.
Once a comet gets close to the Sun then it’s heat melts the ice and causes some of the ice to “sizzle.” Since there is no medium that is why there is no sound in space, this all happens silently.
Some comets have very high elliptical orbits that bring them close to the Sun. As when these comets near the Sun the ices found in them melt and some brilliant features are formed. Below there is a list of these features.
Nucleus– The main part of a comet is called the nucleus, not of an atom. It is made of frozen water and gases with little bit of dust and rock. The nucleus is usually a few miles long.
Comma– Most of the time a comet has only its nucleus. But when the sun comes means when they come near it then the Sun’s heat causes it to shed gas and dust.
An Huge cloud of gas and dust that is called a coma like shape builds up around the comet. Usually a comma like this ” , ” but this comma is sometimes larger than Earth.
Tail- When a comet moves more closer to the sun it grows tails. This happens because the sun’s source of energy gives off energy and streams of particles.
They push some of the comet’s dust and gases out into a long stream. Comets basically have two “tails,” like a monster, one that is for the gas or ion tail and the other as a dust tail.
The coma is made of gasses such as mixtures of ammonia, water vapor, and carbon dioxide.
Comma tails can be even long—as long as the distance from Earth to the sun. The coma and tails last only while the comet is little close to the sun.
When comets pass near our sun, they release gases because they warm up, this is called outgassing.
The nucleus of a comet that is made up of rocky materials and ice. Then isn’t it a rock and cool thing?
Most of the comets have a diameter of between 10-100 km, although some have reached 100 km in diameter.
When we see a comet in the night sky, the most beautiful part of the comet is the bright wisp of its tail.
When a comet is at its most close point in orbit to the sun it’s called a “perihelion.” Then what it’s farthest away? It is called “aphelion.”
While a comet is outgassing it creates a coma and also a tail. This is the long stream that you can see behind a comet.
A comet itself is relatively small, on an average only 10 miles across, but the tail of a comet can be up to 15 times more longer than the Earth’s diameter.
Isn’t it a interesting one?
At last the ice will burn off of a comet and it will just be a metallic rock with no coma or tail.
When this happens then these comets are said to have gone extinct (that means finished).
More than millions of meteors enter the Earth’s atmosphere not in a year not in a month but every day. But Most of them are around the size of a pebble.
Comets are believed to originate in one of these two regions – Oort Cloud, or the Kuiper Belt found beyond the orbit of Neptune and the dwarf planet Pluto.
The Oort cloud is an outer region of the Solar System 50,000-150,00 times the distance of travel from the Sun to Earth. It is believed to contain some dormant comets. Some of the comets that originate here have orbits lasting more than millions of years.
The Kuiper belt is a part of the Solar System that lies beyond the planets and even the orbit of Neptune. It is much larger than the asteroid belt between Mars and Jupiter.
What are meteoroids, meteors, and meteorites?
And why am I talking about it? But they both are related.
A meteoroid is a small piece of material like rock or metal that has broken off from a comet or an asteroid. Now I think that you got it, that’s why I am talking about it.
Meteoroids can form as debris from comets or asteroids colliding speeding by the Sun.
Meteors are that kind of meteoroids that get pulled into Earth’s atmosphere by the Earth’s gravity. When a meteor hits the atmosphere then because of friction it gets heated up and burns with a bright streak of light called a “falling star” or a “shooting star.”
Sun heat breaks down the basic structure of the comet and as it gets close to the sun the comet “sheds” parts of its contents. Because of this breakdown, scientists think that comets have a limited life like you and me.
According to scientists there are about 3,576 known comets, with one occurrence visible from the Earth in every ten years.
If comet is a periodic comet, then it’s indicated with a “P/” followed by the year of its discovery, a letter that indicates the half-month that it was discovered, then a number that shows the order of discovery.
An example of how this thing works would be if a comet was discovered in the first half of January, 2016, then it would be called P/2016 A2.

Halley Comet is named after an astronomer Edmond Halley who first determined its period of orbit.
It was the first comet to have a periodic orbit.The is also a first short period comet.
There is also a comet know as Biela’s Comet, a short-period comet named for the astronomer Wilhelm, Freiherr (baron) von Biela (1782–1856).
Do you know that NASA launched several unmanned missions to study these comets? A paparazzi of sensor-laden craft buzzed Halley’s during its last coming in 1986.
Most famous comet.
The Shoemaker-Levy 9 comet gave chance to astronomers to see the first impact event of solar system objects. In July 1994, astronomers became its witness.
the Shoemaker-Levy 9 comet impact on the planet Jupiter. It’s estimated that the impact of that energy was equal to six million megatons of TNT
Helly most known comet.
We can see it from Earth every 76 years. Halley’s comet is one of the most famous comets throughout human history. It was observed in1531, 1607 and 1682. It’s considered a periodic comet because it can be seen every 75 years.
It was last seen in 1986 and will return around 2061.In July 1994, the Shoemaker-Levy 9 comet broked and collided with Jupiter. This event gave astronomers an unique chance to observe what happens when such a collision occurs.
In this article we learned-
We have learned many things about it like it’s part and one more thing that not only cats and animals can have tails but comets can also have. And also about its Helly comet and many more such interesting facts about comets.
