Comets
Comets are small solar system bodies that orbit around the Sun. They have a tail (trail of light) when traveling in space.

Which is closer to the sun asteroids or comets?
It all depends on time in reality, or a given period of time comets can follow a path that comes very close to the sun, although this may occur once over a cycle of hundreds of years. Jovian planets are all located past the frost ring where the asteroid belt can be found. (asteroid belt is in between Mars and Jupiter) Depending on time and what you are looking for asteroids hold the most consistency on average of being closer to the sun.
What do scientists call the study of comets and other things related to space?
Scientists refer to the study of comets and other celestial bodies as astronomy or astrophysics, depending on the specific focus of the research. Cometary science involves studying the composition, behavior, and origins of comets, while broader astronomical research includes investigating the entire universe, including stars, planets, and galaxies.
What is each 4 main parts of a comet made of?
The dark colouration of the nucleus can be observed, as well as the jets of dust and gas erupting from its surface..
Nucleus
Albedo
Layer of Dust
Comets are very cold objects with no atmospheres and very weak gravity. When they go close to the sun the violently eject jets of gas.
What can you see in the sky an asteroid a comet or a meteor?
If you land a space ship on a comet or asteroid, then you can touch those (at great peril); meteorites are meteors that have struck the Earth, so you can touch those here on Earth with much less peril.
No. Comets are not flammable and there is no oxygen in space to support combustion. When a comet gets close enough to the sun the ice it is made of starts to vaporize due to the heat, creating a cloud of gas and dust.
Do comets have very low eccentricities?
No, comets typically have high eccentricities in their orbits. This means that their paths around the Sun are elongated and not perfectly circular. The eccentricity of a comet's orbit can vary widely depending on its specific trajectory and interactions with other celestial bodies.
A comet is a ball of ice and dust that orbits the sun. As it gets closer to the sun, the heat and radiation from the sun cause the surface of the comet to be blown away, creating a tail that points away from the sun.
How long can the period be for a long period comet?
Long-period comets have periods of over 200 years.The longest would probably be somewhere around a million years (comparable to the orbital periods of objects in the Oort cloud); much longer than that, and it will go away far enough to be captured by the gravitational field of other stars.
Is Ceres the biggest of an asteroid or a comet?
Ceres is smaller than any planet; even smaller than Pluto.
Is a comet referred to a dirty snowball considered to be a theory?
Yes, the term "dirty snowball" is a popular theory used to describe comets. It suggests that comets are made up of a mixture of ice, rock, and dust, giving them a snowy appearance when they approach the sun and heat causes the ice to vaporize. However, recent studies have shown that comets may be more complex than just dirty snowballs.
It is formed from gas and ice and dust. A comet is from a asteroid belt. It is between Mars and Jupiter and is home to many comets. The tail of a comet is made up of gas and dust and ice. Comet means long haired star because its tail is so long.
Will halleys comet kill us in July 28th 2061?
No it won't. It will be seen from Earth, but it will be a long way from Earth, so it poses no danger to us. You can see many things in the sky at night that are a very long way away. Right now Halley's Comet is too far away to see, but when it is close enough to see, it will still be a very long way from Earth in 2061, just like it was when it was seen in 1986 and in 1910 and other previous occasions that it has been seen from Earth.
How does an asteroid form from comet?
Virtually impossible.
For a comet to do this it would have to already contain a stony and/or metallic core (i.e. an asteroid), then slowly over time lose its outer icy layer. However to the best of our knowledge comets do not have such cores, they are ices and dust and a mixture of various sizes of small stones. Once the ices are lost the dust and small stones spread out in the orbit previously occupied by the comet (if this orbit intersects earth's orbit it produces often spectacular annual meteor showers).
Who was the finder of Halleys Comet?
The earliest recorded appearance of Halley's Comet was by Chinese astronomers around 239 / 240 BC. It was recorded by astronomers in many cultures, but was not known to be the same comet.
Credit for the discovery of Halley's Comet as the same, returning comet, goes to Edmond Halley. Halley had investigated historical records of 24 comets appearing near Earth between 1337 to 1698, and noted similarities in orbits and other parameters between three of them - the ones that were recorded in 1531, 1607 and 1682. In 1705, he published "A Synopsis of the Astronomy of Comets", demonstrating that the comet which appeared to return about every 76 years was likely to be the same comet. Halley predicted its return in 1758, something which he did not live to see, but which was proven to be the case. We cannot know who originally observed the comet that we now call "Halley's Comet". There were documented observations of the comet as early as 240 BCE. Notes from the Talmud indicate that this was a re-appearance of the comet, so people had remembered seeing it before.
Halley's Comet is a fairly short-period comet, becoming visible about every 76 years. It got the name "Halley's Comet" because in 1705, Edmund Halley predicted the year that it would re-appear in 1758. He based this on historical observations. The French astronomer Nicolas Louis de Lacaille proposed naming the comet in Halley's honor in 1759.
When is Halley's comet due to come back?
Will next appear in mid 2061. Halley's Comet will next appear in the year 2061. for more info click on the link http://en.wikipedia.org/wiki/Comet_Halley
What is the diameter in the exact size of units is the coma of a comet?
Comet Tempel 1, as viewed by the Stardust-NEXT mission Credit. The total brightness of coma and nucleus is 10 units, the coma is 9 units.
What is the mass of Comet Encke?
All comets, including Encke, are made of rocks, ice, dust, and frozen gases such as ammonia, methane, carbon monoxide and carbon dioxide. The center of a comet is sometimes referred to as a dirty snowball.
What is Halley comet is and why it is important in 1066?
The asteroids, comets and meteoroids are important to the solar system because they are the main raw elements of planets.They are also important because they were to be believed as ancient remnants of the earliest years of the formation of our solar system.
Why doesn't the ion tail extend in different directions during most of the comets orbit?
As the comet approaches the sun, it gets heated up, and its surface begins to turn into a gas (sublimates). The gas then escapes from the comet, and with enough force to blow away some dust and small rocks from the comet. This dust and gas is what makes the tail and also why the tail always points away from the sun (even when the comet is running from the sun, so the tail is in frount of the comet).
