It's so diffuse that the Earth has passed through comets' tails without anybody except scientists noticing.
On the second-to-last pass of Halley's, spectroscopy revealed cyanide, a poisonous gas, in the comet's tail and there were localized panics that the Earth would be gassed to death. Of course, nothing of the sort happened because the thinness of the gas amounted to less than one molecule per person.

What is the most dense material in the world?
try this website, its very helpful http://www.google.com/
A small icy object that can have a tail 10 million km long?
These are comets. They are usually in very eccentric orbits around the sun, spending most of their time way out beyond the orbit of the outer planets. Here it is cold and they have no tails. They are also very difficult to detect here as they are quite dark, small and the distances are large. As they orbit closer to the sun the surface heats up, and the ice vapourises. Two tails are often formed, a gas tail which points directly away from the sun, effected by the solar wind, and a dust tail which is left behind in the path of the orbit.
Very dense material when heated will give off a spectrum?
if using sunlight, will give off a continuous specturm
Why are comets considered minor members of the solar system?
Comets are very small when compared to the planets.
How did Comet west change the way astronomers think about comets or the solar system?
comets could be very bright

Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.

In which material does a light ray entering from air slow down more?
Glass, since glass is a very dense material it will take a while for the light to enter.

How dense is gold?
very very dense :)
What part of the rain forest is very dense?
Most of the rainforest is very dense, but the understory and canopy are both pretty dense. The canopy and the understory are both very dense but the undersrory is the most dense.

What makes Halley's comet a comet?
its tail has a blueish color trail. -- Other then its tail like figure in space (which is made of gas and dust), just about all comets have similar traits, such as how they are made of ice of very deep cold temperature, almost as cold as dry ice. Except the ice, they also have the similar trait of having dirt attached to them or even in them, which is why some people call comets a "dirty snowball."
How are comets asteroids and meteorites different?
Asteroids orbit the Sun between the orbits of the planet Mars and the planet Jupiter. Comets orbit the Sun on very elliptical orbits, originating from the Kuiper belt beyond the orbit of Neptune or the Oort cloud at the edges of the solar system. Comets are also usually (but not always) icy bodies that give of gas and dust (a tail) as they approach and get heated by the Sun. Meteorites are bodies that were Asteroids or Comets that have hit the planet Earth and landed on the surface.

What is the benefit of buying a goosedown comforter?
The benefits are many! Down is the warmest comforter material, it will last and remain fluffy for years, and is very dense and soft.
