Comets are made of ice, rock, cosmic dust, ammonia, carbon dioxide, methane ice and water. Density will vary depending on it's exact composition. Being that its primary component is water ice, it's specific density will be very close to 1. That is a comet is likely just less dense than water. A large comet if landed softly in the ocean would probably float.

Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.
Solar winds blow the debris of the traveling comet to make it appear it has a tail.
No. The tail of a comet is just dust and vapor blown away from the comet by the solar wind. It is visible only because it reflects the Sun's light. The closer the comet is to the Sun, the more vapor and dust will be released, and the longer the comet's tail will be.It also depends on our viewing angle to the comet is. If the comet's tail is perpendicular to our line of sight, the comet tail will appear longer. If the comet's tail is pointed toward Earth or away from it, then the tail may appear very short or may not be visible at all.
When a comet passes through the inner solar system, it gets closer to the Sun, which causes the Sun's heat to vaporize the comet's icy surface. This creates a glowing cloud of gas and dust around the comet, called a coma, which reflects sunlight and makes the comet appear bright. Additionally, as the comet moves closer to Earth, it may also appear brighter in the night sky.
A heavenly body with a fiery tail is called a comet. Comets are icy bodies that heat up and release gas and dust as they approach the Sun, creating a glowing tail that can be seen from Earth.

Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
Beacause it completes its orbit in 76 years.
every 76 years
About once every 76 years.
Yes.
The sun makes a comet appear bright. A comet is usually made up of ice and rock. The ice reflects the light of the sun very well.
Solar winds blow the debris of the traveling comet to make it appear it has a tail.
