The coma is a giant cloud of dust and gases around the nucleus.
The smallest part of a comet is likely the dust particles that make up its coma, which is the cloud of gas and dust that surrounds the comet's nucleus. These dust particles can be as small as a few micrometers in size.
No, Haley's Comet is not part of the Oort Cloud. It is a periodic comet that belongs to the Jupiter family of comets, originating from the Kuiper Belt. The Oort Cloud is a theoretical region of space much farther out in the solar system than where Halley's Comet originates.
Such objects can have several different names, depending on their location in the solar system and/or their characteristics. If the object is close enough to the sun to off-gas some ice or other volatile compounds, it is a comet. If it orbits the sun, inside the orbit of the outermost planet, it may be a meteoroid or asteroid, depending on the size. If it lies outside the planetary orbit, it may be a Kuiper Belt Object. If it orbits a planet, it may be a moon, if its big enough, or part of a ring system, if it's small, and accompanied by many other similar objects.
Comet Cupid and Vixen are both reindeer that are part of Santa Claus's fleet. They are popularly known as members of the team that pulls Santa's sleigh during Christmas Eve to deliver presents around the world.
Yes. The solar system is everything that orbits the sun.
the name
The nucleus is the solid part of a comet.
The bright glowing gases at the central part of a comet are called the coma. They are produced as the comet comes closer to the sun and the heat causes the ice and other volatile compounds on the comet's surface to sublimate, creating a cloud of gas and dust around the nucleus.
Halley's comet, the actual solid nucleus part, is around 8km wide by 15km long. It's gas and dust tails can be spread out over millions of km though. The diameter of the Earth is around 12,700 km, so by contrast, the diameter of the nucleus of Halley's comet is around 0.1% the diameter of Earth.
The coma of a comet is formed due to melting of the comet's nucleus by the Sun's energy. This creates a cloud of gas and dust that surrounds the nucleus and forms the visible atmosphere of the comet.
The nucleus of a comet is the solid, icy core of the comet. It is composed of a mixture of ice, rock, dust, and organic compounds. As a comet gets closer to the Sun, the heat causes the nucleus to release gas and dust, forming the characteristic coma and tail of the comet.
The nucleus and the coma compose the core of the comet. The nucleus is the solid, rocky part at the center, while the coma is the surrounding cloud of gas and dust that forms as the comet gets closer to the Sun and begins to vaporize.
The densest part of a comet is typically its nucleus, which is a solid, icy body made up of dust, rock, and frozen gases such as water, ammonia, methane, and carbon dioxide. The nucleus is surrounded by a coma, a cloud of gas and dust that forms as the comet gets closer to the sun and begins to heat up.
Me
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.
Near the sun: A cometary nucleus has a "corona" (a vapor outgassing of it's nucleus, up to a million times wider than the comet itself - this is what we see as the "head" of the comet), and one or several "tails". The "tail" we usually see is the vapor trail, but sometimes a secondary gas trail is also visible. Far from the sun, it is just the nucleus. Typically 3 to 10 kilometers wide, oddly shaped, like a potato or a peanut and, somewhat surprisingly , very dark in color, like soot.
