What is the dirty snowball theory?
What are comets made of? Gravity holds stars and planets together, but what holds the other (little stuff) together. Ionic bonds. And it turns out that are only 3 that seem to work: Water (ice), Silicon oxide rock, and ferromagnetic metals (iron, nickel, cobalt). Comets don't seem to have much metal, so "dirty snow-ball". In 1949, Fred Lawrence Whipple theorized that the nucleus of a comet is made of frozen water, rocky debris, and frozen gases. This was called the "icy comglomerate" theory and is now known as the "dirty snowball" theory. However, in 1999, the Stardust spacecraft was launched and in 2004 it retrieved tiny particles from the comet Wild-2's surface and came back two years later in a capsule, landing in Utah. Minerals that formed in the presence of liquid water were discovered, proving that, at some point, pockets of water had existed on the comet. This disproved the "dirty snowball" theory.
A dirty snowball that orbits the sun?
A dirty snowball orbiting the sun is likely a description of a comet. Comets are made of ice, dust, and rocky material, forming a nucleus that is surrounded by a glowing coma and a tail when they get close to the sun. These celestial objects have highly elliptical orbits that bring them close to the sun and then back out into the far reaches of the solar system.
What is halleys comet made of?
All comets, we believe, are composed of a lot of ices such as frozen carbon dioxide, nitrogen, oxygen, water, and other gasses, with a lot of dust and some rocks. Science fiction writers Jerry Pournelle and Larry Niven described a comet as a "dirty snowball".
Large dirty snowball that orbit the sun?
Comets are large dirty snowballs that orbit the sun. Made up of ice, rock, and dust, comets develop a glowing coma and a tail when they get closer to the sun due to the heat causing the ice to vaporize. They follow elongated orbits that can take them close to the sun and then far out into the solar system.
What is the ball of dirty ice orbiting the sun?
The ball of dirty ice orbiting the sun is a comet. Comets are made up of dust, rock, and frozen gases such as water, methane, and ammonia. When they get closer to the sun, they heat up and release gas and dust, creating a glowing tail.
Why is comet called dirty snowball?
because they are made of rocky balls and ice.
Is a comet a dirty snowball?

In outer space what is a bunch of dirty ice called?
"DIRTY SNOWBALL" : a description of a "comet", which ordinarily orbits the Sun and partially disintegrates (from heating) to form its "tail" as it gets closer to the Sun.
What is the name of the first comet?
its called a dirty snowball because of the wau it looks
Facts about halleys comet?
it is made up of ice and dirt and is therefore also known as a "Dirty Snowball"
Described as a dirty snowball what is composed of ice frozen gases and rock?
A dirty snowball is a comet, which is composed of ice, frozen gases (such as carbon dioxide, methane, ammonia), and rock. When a comet travels close to the Sun, the heat causes the ices to vaporize, creating the tail that we see from Earth.
What is comet made of?
A comet is often described by Astronomers as a 'Dirty Snowball'. This is because a comet comprises of Ice, from frozen gases mixed with dust and other particulate matter, collected on its orbital path.
