The layer that surrounds the radiation zone of the sun is the convection zone. In this zone, energy is transferred by the movement of hot plasma rising and cooler plasma sinking, creating a convection current. This process allows energy to be transported from the core to the surface of the sun.
It seems like you might be referring to the term "atmosphere." The atmosphere is the layer of gases that surrounds Earth and other planets. It is crucial for supporting life, providing oxygen, and regulating temperature.
Comets are usually made of high amounts of Hydrogen, Nitrogen, Water, and also may contain Silica, traces of metal, and oxygen, like a giant dirty snow ball. In space as the cosmic radiation smashes into the comet at near speeds of light and heats the outer layer, bits and pieces fall off and trail behind the comet. For a relatively short while, the chunks fortunate to stay in fairly good sizes or obscured from the light by other chunks or dust, are able to maintain these materials. After gases sublimate and and break down into neutrinos and electrons and such things. The remains are the tougher elements such as silica and metal, However after a while these eventually break up also.
The layer you are referring to is the outer core of the Earth. It is composed mainly of liquid iron and nickel due to intense heat and pressure. The movement of this liquid outer core is responsible for generating the Earth's magnetic field.
Classic! That would be a "coma," often found surrounding the nucleus of comets.

The nucleus is in the center of the lens, the cortex surrounds the nucleus, and the capsule is the outer layer.
The nucleus of a comet, which is its solid core made of ice, rock, and dust, has only been seen by a space probe. This is because the nucleus is covered by a thick layer of gas and dust that forms the coma and tail of the comet, making direct observation from Earth difficult.
The double layer of membrane surrounding the nucleus is called the nuclear envelope. It consists of an outer and inner membrane with pores that regulate the passage of molecules in and out of the nucleus.
The Coma is the fuzzy outer layer of a comet.
The membrane surrounding the nucleus is simply called the nuclear membrane. It is a phospholipid bilayer. The nuclear membrane merges with the endoplasmic reticulum, and you can learn more by using the link below.
The lithosphere surrounds the asthenosphere.
The mantle surrounds the outer core
that is the thick excel layer
