Solar wind contains intense clouds of high energy particles which are produced by solar stroms. These clouds of particles affect Earth. These clouds are called coronal mass ejections. They reach the earth in three to four days.
The coronal mass ejections cause changes in the magnetic field of the earth when they collide with the field. They cause more changes to the magnetic field at times even at lower altitudes close to the ground when they leak through the field especially near the north ans south Poles. These changes can produce many problems with electrical equipment.
Not much light has been thrown on the way in which solar wind" plasma" invades the Earth's magnetic field and seeps into the inner regions where the Van Allen radiation belts are located. Also, in the direction opposite the Sun, the Earth's magnetic field is pulled way out into interplanetary space making it look like a comet. Many different electrical disturbances take place in this "geotail" region. These can accelerate partiles to high speeds and energies. All of this is made much more violent by the solar wind, especially the strom clouds that the Sun launches our way very often.

∙ 14y agoComets have been called "dirty snowballs", because they are composed of rocks and dust primarily bound together with ice and frozen gasses. As the comet approaches the Sun, the heat of the Sun causes the frozen gasses to be vaporized, or "sublimated". The vapor also carries away some of the dust, which is then pushed away from the Sun by the pressure of the sunlight. It is the vapor and dust that catch the sun's light to form the tail of the comet.

What state of matter is comets?
The nucleus of a comet is mostly solid, while the coma and tail of the comet is composed of gasses and (we believe) a lot of dust. As the comet approaches the Sun, sunlight heats the nucleus of the comet and melts some of the frozen gasses, which sublimate into space carrying dust into space, forming the coma and the tail of the comet.
Which part of the comet exists when the comet is close to the sun and also when it is far from the sun?
The nucleus is the bulk of the comet, this is present all the time until it eventually breaks up after many orbits. close to the sun, it gives of two tails as the sun heats the comets surface. Far from the sun it would just look like a rock that also contains a high proportion of ice.
What part of the sun shapes the comet into a shimmering tail?
Basically the evaporated gas of whatever the comet nucleus is made of. Often methane, ammonia, carbon mon- and di-oxide. A very good article is in the link below. However, due to relative motion and a few other forces, the tail is not all that straight.
A cleanser with the name to a celestial body with a nucleus and a long tail?
Comet
Why do comets have long trails?
Comets have been compared to "dirty snowballs", made of rocks and dust held together with frozen gasses. When a comet starts to come near the Sun, the sunlight begins to heat it up, vaporizing some of the frozen gasses. The dust in the ice is carried away with the vapor, and the light pressure from the Sun pushes the very light dust and vapor away from the comet's nucleus. The light illuminates the dusty vapor, and we see the comet's tail begin to grow as the comet comes closer to the Sun.The length of the tail is dependent on the nature of the frozen gasses, and on how much dust the tail carries away, and on how close the comet comes to the Sun. Some comets don't come especially close to the Sun, while some come VERY close. And some comets fall into the Sun completely. (The size of any comet is so tiny compared to the size of the Sun that a comet-Sun collision has no effect on the Sun at all. It would have less impact than the force of a mosquito hitting the windshield of a train.)
Where do the 3 main parts of a comet go?
The three main parts of a comet are the Nucleus, the Coma, and the Tail. The nucleus is the comet itself. In deep space, the comet is frozen solid and almost invisible. As the comet approaches the sun, the Sun's light heats the nucleus of the comet and causes frozen gasses to melt or sublimate, forming a sort of atmosphere around the comet. This is the "Coma" of the comet. The sunlight causes the gasses around the comet to glow. But the gravity of the comet's nucleus isn't strong enough to hold on to an atmosphere, and the Sun's rays push the glowing gasses away from the nucleus, directly away from the Sun. This stream of glowing gas is the "tail" of the comet. It's important to note that the tail of a comet doesn't drag behind the nucleus; the "tail" goes straight from the nucleus away from the Sun, so the "tail" sometimes extends AHEAD of the comet. Because the material of the comet nucleus gets melted and loses mass every pass by the Sun, comets have a limited lifespan. At some point, each comet will break apart into pieces and disappear, leaving only a meteor shower in its wake.
How does the sun create a tail on a comet?
The sun creates a tail on a comet because of solar radiation and solar wind on the nucleus of the comet. A comet is an icy body that is seen when it passes close to the sun.
What is the correct term for the halo light around a comet?
The Coma is the nebulous envelope around the nucleus of a comet. It is formed when the comet passes close to the Sun.
Which part of the comet exists both when the comet is close to the sun and when the comet is far away from the sun?
Near the sun: A cometary nucleus has a "corona" (a vapor outgassing of it's nucleus, up to a million times wider than the comet itself - this is what we see as the "head" of the comet), and one or several "tails". The "tail" we usually see is the vapor trail, but sometimes a secondary gas trail is also visible. Far from the sun, it is just the nucleus. Typically 3 to 10 kilometers wide, oddly shaped, like a potato or a peanut and, somewhat surprisingly , very dark in color, like soot.
How was Halley's comet created?
It was created like any other comet: Ice chunks fuse together to the nucleus of the comet and it obtains an orbit around the sun.
How do you vaporize gas around a comets nucleus?
You don't need to; the Sun does a fine job of vaporizing the volatile chemicals in the nucleus of a comet.
What state of matter is comets?
The nucleus of a comet is mostly solid, while the coma and tail of the comet is composed of gasses and (we believe) a lot of dust. As the comet approaches the Sun, sunlight heats the nucleus of the comet and melts some of the frozen gasses, which sublimate into space carrying dust into space, forming the coma and the tail of the comet.
What part or parts of a comet come and go during a comet's orbit?
During a comet's orbit, the coma and tails are the parts that come and go. The coma is the glowing, fuzzy cloud around the nucleus that develops as the comet gets closer to the Sun. The tails, consisting of ion and dust tails, form as a result of solar radiation and solar wind pushing the coma's particles away from the nucleus. Both the coma and tails diminish as the comet moves away from the Sun during its orbit.
What diretions does the tail of a comet point?
A comet's "tail" points away from the Sun. Moving away from the Sun, that means that the comet is moving "tail-first" through space. This is because the comet's tail is actually just wisps of gas and dust melting out of the "nucleus" or head of the comet. The light of the Sun actually has a pressure, and this solar pressure blows the dusty gas away from the comet itself. It is this dusty gas reflecting the Sun's light that we see.
What is the large halo made of dust and gas that forms around the the nucleus of a comet when it is close to the sun?
coma
What is the name of the celestial body with a nucleus composed of dust and rocky fragments and ice and which forms a luminous diffuse tail when near the sun?
Comet.
What is the hazy layer that surrounds a comet and nucleus?
The "coma".
