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.

Which part of comet is on the opposite side of a comet from the sun?
Solar winds blow the debris of the traveling comet to make it appear it has a tail.
When did Halley's comet appear in the 20th century?
Halley's comet appeared in 1910 and 1985 (about every 75 years).
Do comets have a tail throughout their whole orbit?
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.
What makes a comet look like a comet?

Why does Halley's comet appear when it does?

How often does halley comet appear and why?
