Comets

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.

Here is what i found for my project on moon colony...

1. It provides more area for life and allows population to grow.

2. It advances our technology.

3. The northern part of the moon's surface is a prime area for growing things. This will allow a colony to grow food supplies to eat. By being able to do this a moon colony just may be possible in the future.

The cloud of frozen comets that surrounds Pluto is called the Kuiper Belt.

Comet Kohoutek was a well-known comet that passed through our solar system in 1973. It was studied extensively by astronauts aboard the Skylab space station during its mission. The observations helped scientists gain insights into the composition and behavior of comets.

Sungrazers are comets or asteroids that pass very close to the sun. Due to the sun's intense heat and gravitational pull, most sungrazers are destroyed or vaporized before they can collide with the sun's surface.

Comets are typically observed before sunrise or after sunset when the sky is dark enough to see their faint tails against the backdrop of space. This is because comets are most visible at these times when they are illuminated by the sun but not obscured by the brightness of daylight.

It is estimated that there are billions or even trillions of comets in the Oort Cloud. These comets are believed to be remnants from the early solar system and are located in a distant region surrounding our solar system.

To determine your age in 2061, you need to subtract your birth year from 2061. For example, if you were born in 1990, you would be 71 years old in 2061 (2061 - 1990 = 71).

Yes, a comet produces light as it travels through space. This light is mainly produced by the Sun's energy causing the comet's nucleus to release gas and dust particles, which reflect sunlight and create a glowing tail.

Comet Swift-Tuttle orbits the Sun once every 133 years, so it won't be visible from Earth until it returns in the year 2126. It is the source of the Perseid meteor shower which occurs annually in August when Earth passes through the debris left by the comet.

This comet was named after the 2 scientist who began the study of the effects of the comets collision with Jupiter. Their names were Shoemaker and Levy, thus naming the comet the Shoemaker-Levy comet. Obviously after crashing into Jupiter the comet no longer exists.

The speed of a comet in its orbit around the sun can vary depending on its distance from the sun. Comets can reach speeds of up to 150,000 miles per hour (241,000 km/h) as they approach the sun and are accelerated by its gravitational pull.

Comet fragments that continue to collide with Jupiter typically travel at speeds ranging from 58 to 117 kilometers per second. These high speeds result from the gravitational interactions of the comet fragments with Jupiter's immense mass, causing them to accelerate significantly as they approach the planet.

Comets are made of frozen gases and ice so when they get too close to the sun the gas and ice evaporate. As they orbit around the sun, the comet forms a tail, and the evaporation causes it to burn and give off light. I wouldn't call it "emitting" light though, because I think that to emit light, the object should be creating the light on its own. Comets don't emit light because without the sun they won't burn in the first place.

You can only see them at night, you can only see them if Earth is facing that way and you can only see them if they come near Earth.

The term for swirling clouds of hydrogen gas out of which stars are born is "nebula."

Some meteorites probably were in the cores of asteroids, once. A meteoroid is a space rock traveling through space, while a meteor is the brief streak of light caused when a space rock hits the Earth's atmosphere. Many meteors burn up completely or explode high in the atmosphere, while some survive to strike the Earth.

Where do the meteoroids come from? Some are probably leftovers from the formation of our solar system. Others may be rocks blasted into space from explosions caused by asteroid impacts on the Earth, or Venus, or Mars, long ago. At least one meteorite found on Earth has been identified as Martian in origin, and other meteorites may have been left over from the time 4 billion years ago when another planet collided with the proto-Earth and formed the Moon!

Asteroids do occasionally collide, breaking into smaller rocks, and it is likely that at least a few of those chunks eventually find themselves falling into the Earth's gravitational well.

There are comets visible from Earth many nights, they are just too faint to be seen easily. So, there is a continuum of brightness -- comets from very faint to quite bright. The brightest are the spectacular ones that get in the news. Also, bright ones may be discovered not long before they are visible. If I remember correctly, McNaught, of January/February 2007, the second brightest comet since 1935, was discovered about 6 months before it came close.

Halley's Comet is unique because it is one of the most famous comets known to humanity due to its regular appearance every 75-76 years. It is also the only short-period comet that is visible to the naked eye from Earth and has been recorded by humans for over 2,000 years. Additionally, Halley's Comet contains a nucleus made of ice, dust, and rocky material that gradually vaporizes as it gets closer to the Sun, creating its iconic glowing tail.

All of them. Even the short-period comets like Halley spend most of their time far out from the Sun; if they spent too much time in the inner system, all of their volatile gasses and ices would melt and sublimate away.

Small lumps of rock orbiting the sun are called asteroids.

Comet orbits are typically elliptical, meaning they are elongated and not circular like planet orbits. This can result in comets having highly eccentric paths around the Sun.

Comets are considered minor members of the solar system because they are smaller and less massive than planets and asteroids. They are composed of ice, dust, and rocky material, and often have highly elliptical orbits that take them far from the Sun. Comets are less numerous and play a smaller role in the dynamics and structure of the solar system compared to planets and asteroids.

One superstitious belief about asteroids is if an asteroid crashed in the surface of the earth, the climate will become hotter. Another is that asteroids will cause great harm to the earth when it passes.

Since science has studied asteroids, there are not many superstitions about them.
