Comets

Comets get smaller as they approach the Sun because the intense heat causes the ice and volatile compounds on their surface to sublimate, turning directly into gas and escaping into space. This process leads to the comet losing material and eventually shrinking in size over time.

Comets are made up of ice, rock, and dust. Their size can vary depending on how much material they have collected as they travel through space. This material can come from the comet's nucleus as well as from debris shed along its orbit.

Meteors typically burn up in the mesosphere layer of the atmosphere, which is located between the stratosphere and thermosphere. This region is where most meteors vaporize due to the friction created by the high-speed entry through the Earth's atmosphere.

Halley's comet appears blue due to the emissions of vaporized gases, such as carbon, nitrogen, and oxygen, as it interacts with ultraviolet light from the sun. The ionization and excitation of these gases cause them to emit bluish-green light, giving the comet its characteristic blue glow.

It is called the cheese comet it is a really funny name for a comet it is called that because it lookes yello when u see it flieing past

The wrong way is a statement of ignorance.. However, we don't know exactly why they would face away from the presumed direction (that being away from itself, or away from the sun) except to assume some other force in space is helping make this so. So, one theory is there is a sort of tidal energy in space and not just a bunch of weak nothing. Perhaps this force is not as potent as gamma rays, as obvious, but perhaps there is enough of it, and enough of where it came from, that it's a very big deal. My suspicion is that even fluctuations in solar activity, jupiter, and our own plate tectonics, could be influenced by the same things which makes the comet tail face the 'wrong way'.

John Hancock was last seen with Samuel Adams on March 5, 1770, in Boston during the Boston Massacre. Hancock and Adams were leading figures in the American revolutionary movement at the time.

No, you will only get one chance of catching it. I suggest you to save the game before you fight Kyogre, so that you can restart your Nintendo if you fail.

A comet is a ball of ice and dust that passes "near" the sun during part of its orbit, which heats it to the point that it outgasses and blows of part of its mass on each orbit, forming a sort of streamer or "tail".

There are lots of comets. The periodic meteor showers we get are debris from comets that have mostly disintegrated. We don't know of any big showy periodic comets like Halley's (usually, its most recent appearance was rather disappointing) due to make an appearance in the near future (unless you consider half a century "the near future). However, there's always hope.

(If by "heading towards Earth" you mean "will hit Earth causing disastrous results" then the answer is no. This can happen, but it's extremely rare and there's no real reason to think a significant impact will occur anytime soon.)

encke's comet that appears every 3.3 years

Comet Halley is mainly composed of dust, water ice, carbon dioxide, ammonia, and methane. It also contains various organic compounds, such as hydrocarbons, cyanides, and amino acids, which are thought to be the building blocks of life.

Comets are thought to have either originated from the Kuiper belt or the Oort cloud. The Oort cloud is much further out than the Kuiper belt, so comets with much longer periods are thought to originate from here, while shorter period comets are thought to mainly originate from the Kuiper belt. The Oort cloud extends as far out as 50,000 AU or nearly one light year from our sun - this is roughly where the boundary is for our solar systems gravitational influence. Passing stars and the gravitational effect of our galaxy are thought to dislodge objects from this hypothetical field of object, causing long term comets such as Halley's comet to enter into an eccentric orbit around our sun. The Kuiper belt, by contrast, extends from about 30 AU to 55AU. Generally speaking, the comets will be similar in composition, but those originating from the Oort cloud may have much longer periods and orbits.

The following would be seen during extended observations of a comet:

-- The object is not shown on charts or maps of the sky. It has appeared where

no permanent object was previously seen.,

-- Its proper motion is significant. It moves among the background "fixed" stars

from one night to the next.

-- Computation of its orbit based on several observations places it inside the

solar system, on a path that is either hyperbolic (open) or else elliptical with

large eccentricity, probably highly inclined to the ecliptic plane.

-- Computation of its orbit also indicates its distance. Once that's known,

and its brightness is measured, its size can be calculated, and it's found

to be very small ... like a few tens of miles in diameter.

-- As the object moves closer to the sun, it becomes brighter, which is to be

expected. But it also becomes larger and fuzzier, as if some surface material

is boiling off, enclosing the solid center in a large, wispy, fuzzy ball.

-- Eventually, the fuzzy envelope begins to elongate, grow away from the

center, and stream out away from the object appearing as a 'tail' or stream

of 'hair'. At first, the fuzz appears to drift off behind the object as the object

moves away from it. But as the path curves and the object eventually swings

around the sun and away from it, it's seen that the shape of the fuzzy envelope

and the 'tail' has nothing to do with the object's motion ... it simply always points

away from the sun, as if some kind of wind from the sun were blowing it away.

Comet cleanser is a powdered cleaning product that is abrasive and mainly used for scrubbing and removing stains and grime. While it can help remove dirt and grime from surfaces, it is not specifically designed or marketed as a disinfectant to kill germs. It's recommended to use a separate disinfectant product to kill germs effectively.

Comets typically take hundreds to thousands of years to return to the inner solar system and replenish Earth with water. The specific time it takes for a comet to return depends on its orbital period and distance from the Sun.

Hale-Bopp was first discovered in 1995. It became visible to the naked eye in May 1996 and remained visible until December 1997.

You can't see Halley's Comet at any time of the day or night now. It was last seen from Earth in 1986 and won't be seen from Earth again until 2061. It orbits the Solar System, taking about 75 to 76 years to do so, so it can only be seen about that often from Earth.

The brightness of a comet is not determined by its distance from the sun, but rather by factors such as the size of its nucleus, how recently it has passed close to the sun, and how much dust and gas it is releasing. Therefore, the brightest comets can be found at various distances from the sun.

The tail of a comet is formed by ice and dust that is blown off by solar winds from the nearest star. That is why the tail will always point away from the star no matter what direction the comet is traveling.

That would be a comet. Comets are celestial objects composed of rock, dust, ice, and frozen gases that orbit the sun in highly elliptical paths. When they come closer to the sun, they develop a glowing coma and a tail that always points away from the sun due to solar wind.

Halley's Comet is visible from Earth roughly every 76 years. The next predicted appearance is in 2061. It was last visible in 1986.

No. A light year is the distance light travels in a year, and nothing can travel faster than light. Therefore, the quickest that anything could travel a light year is 1 year. A comet travels much slower than light.

There's nothing all that special about the comet itself other than that it happenes to be the first one that was successfully predicted. Halley realized that several of the comets reported in historical accounts were probably the same object orbiting the sun with a period of about 76 years and predicted its return (unfortunately, the period was long enough that he died before seeing his prediction came true).

No, globular clusters are large groups of stars that formed together at the same time. They are much larger and contain thousands to millions of stars, unlike small asteroids, and were not the building blocks of planets.
