Loose collection of rock and frozen gas that has a tail?
A comet
How does a comets appearance change as it approaches the sun?
As a comet approaches the sun, it typically develops a bright coma (cloud of gas and dust) and a tail that points away from the sun due to solar radiation. The heat from the sun causes the ice in the comet to vaporize and release dust particles, creating these features.
What is an icy rock that has bright tail when it comes close to the sun called?
It is called a comet. Comets are made of rock, dust, ice, and frozen gases, and as they approach the sun, they produce a glowing, bright tail due to the interaction between the comet's material and solar radiation.
What mass of material with a long tail travels around the sun?
The mass of material with a long tail that travels around the sun is called a comet. Comets are composed of ice, dust, and small rocky particles. The tail of a comet is formed when it gets closer to the sun, and the heat causes the ice to vaporize and create a glowing tail. The mass of a comet can range from a few million kilograms to billions of kilograms.
Does comet tail possible to can seen pointing towards earth?
A comet's tail points away from the sun. Sometimes the dust and gas separate, though, because they are driven by two different effects, radiation pressure and solar wind, respectively. Both point mostly away from the sun, but not always exactly. Photographs of Comet Hale-Bopp show this effect well, for example, the Astronomy Picture of the Day at the link shown. A comet in deepest cold space is generally thought of as a giant dirty snowball with the snow made of water ice, and frozen organic liquids, and the dirt of small rocks and dust which are the debris of explosions and collisions of different bodies in space. It is only when the comet approaches the sun and warms up that surface ice melts and vapourises carrying dust with it and forming a large cloud that we can see clearly. It is at this stage when the effects mentioned above act on the cloud and sweep it behind the comet relative to the sun to form a tail or tails, and because there is no atmospheric air in space the tail always points away from the sun even when the comet is travelling away from it.
Is it possible for a comet to have no tail at its perihelion?
It is theoretically possible for a comet to have no tail at its perihelion if the comet does not contain enough ice and other volatile materials that can vaporize and form a tail when heated by the Sun. However, it is rare for a comet to lack a tail entirely at perihelion, as most comets are composed of volatile materials that create a visible tail when heated by the Sun.
The tail of a comet is longest when the comet is?
The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.
How is the tail of a comet created?
The Comet's Tail forms when sunlight causes the Comet's ice to change to a gas. The gas or ion , tail of a comet streams from the comet's head, carrying with it dust particles. The solar wind electrically charged particles, expand away from the sun pushes the gas away from the comet's head. Regardless of where its going the tail points away from the sun.
What direction does the tail of a comet point in relation to the sun?
The tail of a comet always points away from the Sun, regardless of the comet's location in its orbit. This is due to the solar wind pushing particles and gases in the tail away from the Sun.
When is the tail of a comet visible?
The tail of a comet becomes visible when it gets closer to the Sun. The Sun's heat causes the comet's ice to vaporize, releasing gas and dust particles that form the tail. This tail can stretch for millions of kilometers away from the comet's nucleus.
Why is a comets tail is in front of the comet?
A comet's tail is always pointed away from the Sun due to the solar wind. As the comet moves closer to the Sun, solar radiation and solar wind push the dust and gas away from the comet, creating the tail that appears to extend ahead of the comet in its orbit.
Is the head of the comet on the opposite side of the comet from sun?
No. The tail of the comet points away from the sun.
How does the sun create a tail on a comet?
The sun creates a tail on a comet because of solar radiation and solar wind on the nucleus of the comet. A comet is an icy body that is seen when it passes close to the sun.
What pushes particles in a comets tail?
The pressure of the sun's light shining on the wispy gasses vaporizing from the comet's head push the tail of the comet away from the sun. While it looks like the "tail" of the comet is trailing behind, the tail always points away from the Sun. So after the comet's perihelion (the closest approach to the Sun) the "tail" is actually LEADING the comet!
Which comet tail always points away from the sun?
The ion tail of a comet always points directly away from the sun due to the solar wind pushing charged particles emitted by the comet.
Which part of comet is on the opposite side of a comet from the sun?
The tail of a comet is on the opposite side of the comet from the sun. The solar wind pushes gas and dust away from the comet, creating a tail that always points away from the sun.
What body forms a tail as it approaches the sun?
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
