Comets

The extent (distance) in which an object takes to orbit around another bigger mass (which is effected by how big the satellite (smaller object) is).

Or the length [of time] of an orbit. This is the time it takes to make one revolution.

Examples: Something just above the atmosphere of the earth takes about 90 minutes.

The moon takes 28 days to go around the earth and the earth take a year to go around the sun.

Comets typically have elliptical orbits, meaning they follow a path that is elongated and can bring them close to the sun at one point in their orbit and then far away at another point. This results in significant changes in their speed and distance from the sun during their journey.

When a comet's dust particles enter our atmosphere, they create bright streaks of light known as meteors or shooting stars. Friction with the atmosphere heats up the particles, causing them to vaporize and produce a glowing trail as they streak across the sky.

To have a comet named after you, you typically need to have played a significant role in the field of astronomy, such as discovering comets or making valuable contributions to the study of celestial objects. Generally, the International Astronomical Union is responsible for officially naming comets and follows specific guidelines and criteria for the naming process.

Comets are considered primitive bodies that have remained relatively unchanged since the formation of the solar system, providing valuable information about its early history. By studying the composition of comets, scientists can learn about the conditions and materials present in the solar system when it was forming, shedding light on its evolution over time. Tracing the trajectory of comets can also reveal clues about the solar system's ancient environment and the processes that have shaped it.

Halley's Comet is non-luminous itself; it does not emit light like a star. However, it becomes visible in the night sky as sunlight reflects off its surface, making it appear luminous to us on Earth.

Comet 46P/Wirtanen is a short-period comet that orbits the Sun every 5.4 years, making it visible from Earth approximately every 11 years. It was last seen in 2018 and is expected to return in 2024.

Yes, comets are mainly composed of ice, dust, and rock particles. When a comet approaches the Sun, the ice on its surface begins to vaporize, releasing gas and dust that form a bright glowing coma and tail.

They aren't poor reflectors of light. Comet's are somewhat invisible when they are in deep space because they are simply a chunk of rock and ice. But when they near the sun and the ice begins to melt off forming a huge tail, the light from the sun reflects nicely off the comet's ice crystals

The scale of damage potentially caused by an asteroid or comet impacting Earth is known as the Torino Scale. It is used to communicate the potential threat level of near-Earth objects (NEOs) impacting our planet.

He is famous for his impact on the music industry and his innovative approach to creating and performing music.

It is highly imporbable that any comet follows a circular orbit. They are much more likely to follow long eliptical orbits in their eccentric wanderings through the inner and outer solar system. Surf the link to our friends at Wikipedia for some pics and more data.

Comets can vary in visibility depending on their size and proximity to Earth. Some comets can be easily seen with the naked eye when they pass close to our planet, while others require binoculars or telescopes to observe. So, it can be easy or hard to see a comet depending on these factors.

A comet's tail is caused by the solar wind, a stream of charged particles emitted by the Sun. As the solar wind interacts with the comet's nucleus, it ionizes molecules in the coma (the comet's atmosphere) and causes them to be pushed away from the Sun, forming the tail that points away from the Sun due to pressure from the solar wind.

more circular and closer to being a perfect circle. Comets typically have highly elliptical orbits that can take them far from the Sun and then swing back in close again, while Jupiter's orbit is more stable and predictable due to its strong gravitational influence in the solar system.

Because comets were created about the same time as the Earth.

Some major events that occurred when Halley's comet appeared include its observation by Edmund Halley in 1682, passing near Earth in 1910 causing widespread fear of poisoning from its gas tail, and its most recent appearance in 1986 when multiple spacecraft were sent to study it.

Yes. Some comets die spectacular deaths, like Shoemaker-Levy 9, which crashed into Jupiter. Some just break up and continue in their orbits. We often find "meteor showers" when the orbit of the Earth intersects the orbit of a comet.

No, Halley's Comet was last visible from Earth in 1986 and is expected to return in 2061. It has an orbital period of about 76 years.

The parent company of Comet is Kesa Electricals. Comet operates as a subsidiary under Kesa Electricals, which is a European electrical retail company.

Haley's Comet, officially known as Halley's Comet, is projected to pass closest to Earth in 2061 on its 76-year orbit cycle. The last time Halley's Comet was visible from Earth was in 1986.

Halle Berry is biracial, with her mother being white and her father being black. She has openly embraced both sides of her heritage throughout her career.

It will next be seen in 2061 because the last time it has been sighted was in 1986 and it comes every 75-76 years so it will be back in 2061.

Mark Twain was born in 1835, the year when Halley's Comet made its closest approach to Earth. Twain famously predicted that he would not die until the next return of the comet. True to his prediction, Twain died in 1910, the year after Halley's Comet's next return.

Comets vaporize when they enter the inner solar system and heat from the Sun causes the frozen gases and dust within the comet to sublimate, turning directly from solid to gas. This process creates a glowing coma of gas and dust around the nucleus of the comet, and sometimes a tail as well.
