They come from the outer reaches of space.
The particles of energy in a comet mainly come from the solar wind interacting with the comet's nucleus and surrounding coma. The solar wind is a stream of charged particles emitted by the Sun that affects the comet's ion tail and can cause energy release through processes like ionization and excitation.
The Comet's Tail forms when sunlight causes the Comet's ice to change to a gas. The gas or ion , tail of a comet streams from the comet's head, carrying with it dust particles. The solar wind electrically charged particles, expand away from the sun pushes the gas away from the comet's head. Regardless of where its going the tail points away from the sun.
In short, the reason of this is the speed they are going, this creates an afterburn effect which heats up the comet therefore creating a 5000 degree tail
No, Halley's Comet was last visible from Earth in 1986 and is expected to return in 2061. It has an orbital period of about 76 years.
Not going to be one
No, a comet will NOT hit earth in 2012.
Halley's Comet
well it might come out this month or next month more ppl think its going to come out next month cuz this month is kinda ending
no
2020 FOR
The Taurids are an annual meteor shower associated with the comet Encke.
Because the comet is going so fast there looks like the comet has a tail.
The Comet's Come-Back - 1916 was released on: USA: 31 May 1916

Halley's comet is a comet named after a Edmund Halley and it comes every 76 years so it will most likely come in 2061
The next predicted perihelion of Halley's Comet is 28 July 2061
