Comets

Comets are small solar system bodies that orbit around the Sun. They have a tail (trail of light) when traveling in space.

What causes the tail of a commet to form?

The tail of a comet forms when the sun's heat causes the frozen gases and dust in the comet to vaporize and stream away from the nucleus. This creates two types of tails: ion tail (gas) and dust tail (solid particles). The direction of the tails is determined by the pressure of the solar wind.

Are comets harder to see when they approach the sun?

Comets can be harder to see when they approach the Sun due to the increased brightness from sunlight scattering off dust and gas in the comet's coma and tail, as well as the proximity to the Sun's glare. However, some comets can become more visible as they get closer to the Sun and develop longer tails that reflect more sunlight.

Are comets from other galaxies?

No, they are not. They come from regions of asteroids that exist within our own solar system. Long period comets, the ones that appear once in thousands of years, probably come from the Oort Cloud, a spherical cloud of small icy asteroids believed to exist at the farthest outer reaches of the solar system. Short period comets like Halley's probably come from the Kuiper Belt, a ring of asteroids just beyone Neptune's orbit. The minor planet Pluto is the most famous Kuiper object. Not all objects in the Oort Cloud and Kuiper Belt are comets; in fact most are not.

What if a comet hit the moon?

1. We would definitely get an awesome show.

2. A handsome new crater on the moon.

3. That is really about it.

When a comet passes through the sun what happens to the ice?

When a comet passes close to the sun, the intense heat causes the ice and other volatile substances on the comet's surface to vaporize and create a glowing coma around the nucleus, forming the characteristic tail of a comet. This process is called sublimation, where the ice transitions directly from a solid to a gas without passing through a liquid phase.

Do planets stars and comets shine as a result of reflected light?

Planets and comets shine because of reflected light because they do not produce their own light. Stars are enormous balls of gas that are undergoing fusion which releases a very large amount of energy in the electromagnetic spectrum which includes visible light. So stars shine because they produce their own light and not because they reflect light.

What does a comet from the Oort cloud have to do with Iowa?

A comet from the Oort cloud has the potential to pass through the inner solar system, including close to Earth and Iowa, as it orbits the Sun. These comets can be visible from Earth as they emit gas and dust while passing through, creating bright tails and making them a spectacle for observers in places like Iowa.

What is the differences and similarities between comets asteroids and meteors?

guess wut comets have 3 parts the head [nucleus] and the tail obviously but the third is the coma that holds the gasses that make the tail meteors are and can become meteors meteorites and meteoroids meteors are passing through our atmosphere meteroids are meteors in space meteorites have hit earth asteroids are basically meteors that have reached 6 miles wide 3 of the biggest ones are considered dwarf planets ceres [eris] vesta and sedan

How fast does hale- bopp travel?

That depends on where in its orbit the comet is. Near the Sun, the comet was moving VERY fast indeed, but in 1200 years or so, a few hundred AU from the Sun, it will hardly be moving at all. And then it will begin to make its long fall back into the inner solar system.

Did a comet hit earth in the ice age?

There is no concrete evidence to suggest that a comet hit Earth during the ice age. The ice age was primarily caused by variations in Earth's orbit, tilt, and wobble, as well as changes in solar radiation.

When is the next hades comet?

It's unclear what you mean by "hades comet." If you are referring to a comet named Hades, there is no specific comet with that name. If you meant Halley's Comet, it will next be visible from Earth in 2061.

Where are general locations of comets?

Comets are generally found in two main regions of the solar system: the Kuiper Belt, located beyond the orbit of Neptune, and the Oort Cloud, a sphere of icy bodies surrounding the solar system at a vast distance. When comets get closer to the sun, they can become visible from Earth as they develop tails of gas and dust.

Can you see a comet without a telescope?

Some comets can be seen without any mechanical help if they are large enough or come close to the earth. Any sort of telescope will help you see more comets if you know where to look and what to look for.

Do comets and meteors have anything in common?

Yes they do, they are both rocks from outer-space. They both have a nucleus and they both travel in space. The thing that comets and meteors have in common is that they all travel in space and most of them all have not changed because of their formation in the solar nebula.

Why is a comet visible for only a short portion of its orbit around the sun?

A comet is visible for only a short portion of its orbit around the sun because it only becomes bright and visible when it gets closer to the sun. As it approaches the sun, the sun's heat vaporizes the comet's icy surface, creating a glowing coma and tail that make it visible from Earth. Once the comet moves away from the sun, it becomes dimmer and harder to see.

What is the physical description of a comet tail?

A comet tail is a long, thin stream of gas and dust that trails behind a comet as it travels through space. It can be millions of kilometers long and is illuminated by the sunlight, creating a bright and dynamic appearance. The tail always points away from the Sun due to solar radiation pushing the gas and dust particles away from the comet's nucleus.

Do comet tails face the sun?

No, a comet's tail always faces away from the sun/

What is shoemaker levy 9 mass?

Shoemaker-Levy 9 was a comet that collided with Jupiter in July 1994. It had a total mass estimated to be around 500 trillion kilograms (500 gigatons). The impact of the comet on Jupiter created large scars on the planet's surface that were visible for weeks.

What is the difference between a comet and an asteroid compared to a meteor?

A Comet:comets are also members of our solar system , they move around the sun in highly elliptical orbits. Their period of revolution around the sun is usually very long. A comet appears as a bright head with a long tail . The tail of the comet is always directed away from the sun. Some comets are known to appear periodically

. One such comet is the Halley's comet which appears nearly after 76years.

Asteroids:There is a huge gap between the orbits of the planets Mars and Jupiter. this gap is occupied by the asteroids , which revolve around the sun between the orbits of Mars and Jupiter.

So , comet is like a body that revolves periodically around the sun whereas there is an asteroid belt already present in the solar system.

Meteor: A meteor is a small object that sometimes enters the atmosphere of the Earth. When it does so its speed is very high , and due to friction it lights up and evaporates quickly. That is why at night sometimes we see a bright streak of light , commonly known as a shooting star.

Sometimes the meteor is too large and does not evaporate completely , and hits the surface of the earth .This body is called a Meteorite.

What is the weight of comet Hale-Bopp?

.42 in comparison to Earth which represents 1

What one is bigger Halley's comet or Ceres?

Ceres is bigger than Halley's comet. Ceres is a dwarf planet located in the asteroid belt between Mars and Jupiter with a diameter of about 590 miles, while Halley's comet has a nucleus estimated to be about 6 miles wide.

Why do you rarely see comets?

Comets spend the majority of their time in the far reaches of our solar system, where they are not easily visible from Earth. They only become visible when they enter the inner solar system and are illuminated by the Sun, hence their rare appearances. Additionally, many comets have long orbital periods, further contributing to their infrequent sightings.

What is the definition of a comet head?

The comet head refers to the spherical cluster of dust and gas surrounding the comet's nucleus, which is primarily composed of ice, dust, and organic compounds. As the comet approaches the Sun, the heat causes this material to vaporize and form the comet's characteristic coma or fuzzy halo.

What is Halley's comet rotation rate?

Halley's Comet does not rotate, but perhaps you mean revolve, as in how long it takes to revolve around the sun.

If that is what you mean, then the revolutionary period of Halley's Comet is about 75-76 earth years.
