Comets

Comets are thought to originate from two main regions in the solar system: the Kuiper Belt, located beyond Neptune, and the Oort Cloud, which is much farther out. Comets are made of ice, rock, and organic compounds, and they develop tails when they come close to the sun and start to vaporize.

Yes, Halley's comet orbits the Sun in an elongated elliptical orbit, which means it travels closer to the Sun and then swings far out into space before returning again on its approximately 76-year journey.

Comets are a mix of dust, rock, and ice, while asteroids are primarily made of rock and metal. Comets usually have a tail when they approach the Sun due to the melting of the ice, while asteroids do not have tails.

No, asteroids are rocky, metallic bodies that generally do not have atmospheres or hydrogen clouds surrounding them. Hydrogen clouds are more commonly found in gaseous planets like Jupiter or Saturn.

It will be back again in 2061. The 1986 flyby was a bit of a disappointment. Comet Kohoutek in 1973 was much better, but it won't be back for another 75,000 years.

Shoemaker-Levy 9 had a short period, as it was a comet that was first discovered in 1993 and eventually collided with Jupiter in 1994. The comet had been fragmented by Jupiter's gravity during a previous close approach, leading to its eventual collision with the planet.

Yes, comets can have a bright streak of light called a tail when they pass close to the sun. This tail is formed by gas and dust particles being heated by the sun, which then reflect sunlight and appear as a streak of light in the sky.

No, not all comets are named after people. Some comets are named after the astronomers who discovered them, while others are given more generic names based on their characteristics or catalog numbers.

Halley's Comet has an orbital period around the sun of about 76 years. Its rotation period on its axis is not well known, but it is estimated to be roughly 2-3 days.

Yes, eating Comet cleanser can harm babies due to its toxic ingredients like bleach and abrasive chemicals. Ingestion can cause serious health effects such as irritation, burns, and poisoning. It is important to seek medical attention immediately if a baby ingests any cleaning product.

Comets in the solar system originate from two main sources: the Kuiper Belt beyond Neptune and the Oort Cloud much further out. These icy bodies are remnants from the early solar system and are occasionally pulled in by gravitational forces into orbits that bring them closer to the Sun, resulting in their characteristic tails.

Comets do not always maintain the same mass. As a comet travels through the solar system, it can lose mass due to the sublimation of its icy nucleus as it gets closer to the sun. This loss of mass can result in changes to the comet's appearance and behavior.

Saturn has not been found to have any comets orbiting around it. Comets are typically found in the outer reaches of the solar system in regions such as the Kuiper Belt or the Oort Cloud, rather than around gas giant planets like Saturn.

There isn't a Susans comet yet (that I know of anyway!), so you will have to get your telescope ourt and start scanning the skies. If you find a new comet you might be allowed to name it Susan.

The three main parts of a comet that are always present are the nucleus (composed of ice, gas, and dust), the coma (a cloud of gas and dust surrounding the nucleus), and the tail (formed when the coma is blown away by the solar wind).

every 133 years

Hades comet, also known as 1P/Halley, has an average speed of about 55 kilometers per second (around 122,400 miles per hour) as it travels through the solar system. It orbits the Sun roughly once every 76 years.

As a comet approaches the sun, heat causes its icy nucleus to vaporize, creating a glowing coma and tail. This transformation is due to the sublimation of volatile substances like water, carbon dioxide, and ammonia, which are frozen at colder temperatures and released as gas when warmed by the sun's rays. This outgassing forms the characteristic comet tail that points away from the sun due to solar radiation and solar wind.

Comets hitting the Sun are rare events due to the vast distances involved in the solar system. The Sun's intense heat and gravity typically vaporize comets before they can impact it directly. If a comet were to hit the Sun, it would likely disintegrate completely or be pulled into the Sun, without causing any significant disturbance.

The dense section of a comet's head is called the nucleus. It is composed of ice, rock, and dust, typically ranging in size from a few hundred meters to tens of kilometers. The nucleus is the solid core of the comet from which gas and dust are released to form the comet's coma and tail when it gets closer to the Sun.

Yes. Every body in this world wil die on the 12th. This is a very hard question for people to answer, but i am a scientist and it is my job to do hard work to discover the world. (i am also very smart). So enjoy the 1-2 years left of your life and don't think about the future.

That is all wrong. God has a plan for us, and anyone who says the exact date or year or time is wrong. I don't care if you're a scientist. God will save those who believe in him in the rapture. Trust me. We are meant to have a long life.... (except those who aren't believers, *Cough* *Cough* Mr. Stupid Scientist)

Ignore the previous answer, as forcing a religious belief onto somebody without any leeway for logical answering is just kinda unfair (no offense to any religious people, and hopefully not the previous answerer). Put simply: no, we won't (and if the first answerer really was smart, s/he would know proper grammar. Anyway, we won't die. 2012 signifies the turn of the Mayan calendar cycle, and it is said that 'whoever lives through this cycle is lucky'. This doesn't mean that it's lucky to survive it, but more that living during a time in which the cycle changes brings luck. Nobody will die (well, no more than usual on a set day), so don't freak.

Comas form around comets when they approach the Sun and heat causes volatile compounds within the comet to vaporize and escape, creating a surrounding cloud of gas and dust. This process is known as outgassing, and it gives comets their characteristic glowing halo.

"Periodic" comets reappear at predictable intervals, such as Haley's Comet.

Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.

The sparse sphere of comets that surrounds the sun and planets is known as the Oort Cloud. It is a vast region of space that is thought to contain billions of icy objects and comets. The Oort Cloud is located far beyond the orbit of Pluto, extending up to about 1.6 light years from the sun.

They have a tail, nucleus (the physical mass that is flying through space). Here s the astronomical sign for comets: ☄

There are most recognizable by their hair like tail.

Looking up to the sky on a starry night you see a comet streaking through the heavens. It looks like a small fuzzy ball with a long hair-like tail. Other times a comet looks like a white streak.

There are three main characteristics to a comet's appearance which are: the nucleus, the coma, and the tail. The nucleus is the solid central part of the comet. This is the actual mass that is traveling through space. The nucleus of a comet is dark, is potato-shaped in many comets, and resembles a dirty iceberg. A comet coma forms when the nucleus evaporates and a large cloud expands around the comet center. This cloud is called the coma. This spherical cloud gives the comet the appearance of a fuzzy ball. The most recognizable characteristic of a comet is its tail. The comet tail also forms when the nucleus evaporates, releasing gas and dust. Both the gas and dust form their own distinct tail. The trail of dust is left behind the comet in its orbit forming a curved tail called the anti-tail or dust tail. The ion tail of a comet is composed of gases and points towards the sun. A comet's tail is what comets are known for. Without a tail it would just look like a spot of light moving across the sky.

Comets can be many different colors including silver, blue, purple and gold at the end of their tail. Comets are usually blue or white at the front part. The color of the comet depends on its distance from the sun.
