The rocky, gritty material in a cometary nucleus is probably much like a solid asteroid in chemical profile. But most asteroids are solid, barren rock - the comet has a large percentage of ices in it.

What is the difference between a composition and an essay?
The words 'composition' and 'essay' are often used interchangeably, as both are literary forms. An essay is a type of composition, but a composition doesn't always have to be in the form of an essay. A composition can be a poem, short story, argumentative essay, or research paper. An essay is more specific, as it is a personal piece on a specific topic.
What is a homogeneous universe?
Imaginary? "Homogeneous" comes from the Greek words "homo" meaning "same" and "genus", which is related to type or composition. So "homogeneous" means "same composition". "Homogeneous milk", for example, is milk that has been so thoroughly mixed that the cream can't "rise" and separate from the rest of the milk. The universe is NOT "homogeneous" by any stretch of the imagination. There are vast expanses of empty space, enormous nebula of tenuous gas and dust, rocks, asteroids, planets and stars. And all of these material objects are each different and unique.
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
What If two minerals have the same chemical composition but cleave into different shapes what is true?
They have different structures.
What is a halley's comet orbit like?
All orbits are ellipses. Some orbits, like the orbit of the Earth around the Sun, are almost (but not quite) circular. Other objects, like the Moon or Mars, have orbits that are more distinctly oval shaped.Comets have elliptical orbits with very high eccentricity; they are stretched so that they come quite close to the Sun, but still go dozens or hundreds of AU away. Some comets are less severely eccentric. Halley's Comet, for example, only goes out to about 30AU with a period of 76 years, while Comet Hale-Bopp has a period of closer to 2200 years.
Are asteroids same as comets?
no
Is a comet an asteroid?
Comets and asteroids are the same, but differ in the fact that comets have surface activity with their characteristic tail.
How are meteors asteroids and comets the same and different?
well meteors are usually boiling like comets, however asteroids are usually a formation of gas and ice but they all form in outer space
How are asteroids and comets the same?
They both orbit the sun.
Are asteroids bigger than comets?
Not necessarily. Both comets and asteroids vary in sides and to a large degree fall into the same size range.
Are asteroids and comets the same thing?
okay i think that they are the same because arnt comets the same as shoting stars and shoting stars are just asterids that came to close to the earth so i think that they are the same. but you might want to ask someone before using this information im only 13. ok no! your way wrong soory bro.. comets have a tail... asteroids don't comets are made up of mostly rock and ice...and asteroids of rock and metals. and by the way, a shooting star is an meteor not and asteroid
Why are planets their moons asteroids and comets not stars?
The moon will not die out. The asteroids and comets are the same. A comet (asteroid) are rocks from space.When it gets to close to the Earth it gets pulled by gravity and it causes this space rock to catch on fire.
What are astriod mostly made of?
Typically, asteroids are silicates (rocks) and water (in the form of ice), which is pretty much the same stuff that comets are made of, except that the big, beautiful comets are mostly water, and the asteroids are mostly rock. Asteroids may also have some metals and someday these may be commercially valuable.
What is part of our solar system comets or asteroids or both?
Comets are often thought of as visitors from other solar systems. Solitary travelers in space. Asteroids can and do exist as "belts" and are usually found in groups that can orbit a central sun very much like planets. Composition can be very different for both objects. Both follow prescribed orbits, hence we are able to predict/know the returning date for Haley's Comet. Am not familiar with any data about asteroids with orbits as far reaching as comets. Because comets follow a predicted orbit, and visit our solar system at regular times, they could be considered part of our solar system the same way as band of asteroids. However, comets can and do leave our solar system and pass through others, so they are more visitor than permanent part of our solar system.
Is a comet smaller than asteroid?
An asteroid is basically a rock in space. A meteor is basically a space rock falling into our atmosphere. Therefore, meteors are asteroids that are falling into our atmosphere, there is no size comparison, only a location and action change.
What does the Andromeda galaxy consist of?
The same as all the other galaxies.Black holes, Stars, Planets, Asteroids, Comets and other space material. Maybe even space junk!!
Were all the planets formed at the same time?
Only God knows.A2. The whole Solar system is believed to have formed at roughly the same time, about 4.5x109 years ago. Much of its materials came from previous super novas.The Earth had a brush with a similar sized planet soon after initial formation, and from the debris, the Moon and Earth were constructed. This other planet we call Theia.
