Comets

The frozen portion of a comet consists mainly of ice, including water ice, carbon dioxide ice (dry ice), and various other frozen gases and compounds. This frozen portion makes up the nucleus of the comet, which is surrounded by a cloud of gas and dust when the comet is active.

Comet Hale-Bopp is known as The Great Comet of 1997. It was one of the brightest and most widely observed comets of the 20th century. People around the world could see it with the naked eye for over 18 months.

Halley's Comet appears roughly every 76 years. It was last visible from Earth in 1986 and is projected to next be visible in 2061. The comet can be seen from various locations on Earth, depending on its orbit and visibility during its return.

Yes. Comets do not enter the atmosphere of the earth (we hope!). What you see is gasses that are released from the comet, illuminated by the sun. However, a meteor (shooting star) is visible only due to the atmosphere heating the meteor.

Halley's comet was last seen in the year 1986. It is seen after every 75 to 76 years, having a relatively stable period affected by Jupiter and Saturn. It can be observed for three or four months before, and several months after its closest approach to the Sun.

It will next be visible to the naked eye in July 2061.

In order of their distance from the sun, the rocky planets are Mercury, Venus, Earth, and Mars.

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.

the Kuiper Belt that is found beyond the orbit of Pluto

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.
