Are comets and asteroids surrounded by hydrogen cloud?
Some comets develop a cloud of hydrogen gas around them when they get close to the sun, due to the sun's radiation breaking apart water molecules in the comet's icy nucleus. This creates a temporary hydrogen cloud known as a coma. Asteroids generally do not have hydrogen clouds since they are composed of rock and metal, lacking the icy material that comets have.
Are asteroids surrounded by a hydrogen cloud?
Some asteroids have been observed to have thin hydrogen atmospheres, but they are not typically surrounded by a dense hydrogen cloud like a gas giant planet. These hydrogen atmospheres are usually very tenuous and not very extensive compared to the atmosphere of a planet.
What is the heart of a commet called?
The heart, or center of a comet is called the nucleus. The nucleus is made of a solid piece of ice surrounded by a cloud of particles and gases.
What is the frozen portion of a comet?
The frozen portion of a comet consists mainly of ice, including water ice, carbon dioxide ice (dry ice), and various other frozen gases and compounds. This frozen portion makes up the nucleus of the comet, which is surrounded by a cloud of gas and dust when the comet is active.
What is the verb for The nucleus of a comet is surrounded by gases and ice?
The verb is "surrounded."
Is Haley's comet part of the Oort cloud?
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.
What surrounds the head of a comet?
A hazy Cloud called coma sorrounds the head of a comet.
What is the hazy layer that surrounds a comet and nucleus?
The "coma".
What is the name of a cloud that contains many comet outside of the solar system?
It is the Oort cloud
Are comets covered in Hydrogen clouds?
In a cometary coma, various hydrogen compounds, especially water, that are photodissociated by solar UV radiation form a gigantic hydrogen cloud with a radius of several million kilometers around the cometary nucleus. These cometary hydrogen clouds have been observed by a number of spacecraft outside the terrestrial atmosphere and in interplanetary space. For instance, the hydrogen cloud of Comet Halley was a good target for the ultraviolet photometers and spectrometers on board the IUE, Suisei, Pioneer Venus, DE-1, and sounding rockets. Hydrogen cloud activity could be used as a good measure of cometary activity, but some problems remain to be explored in the future.
What is the densest part of a comet?
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.
What is comet hale bopp part of?
The Oort Cloud of comets.
