Comets

yes it does, most comets contain water usually D20 deuterium, (heavy water). Earth was bombarded for millions and millions of years in its early stages that is why we have water on our planet. simple!!!!!

our earth would be then fried, becasue the orbit of a comet orbits around the sun which cause the comet to be insanely high. which in one case would fry our earth if our orbit was near the sun

Comet Wild 2 originated from the Kuiper Belt, a region beyond Neptune that contains icy bodies and comets. It originates from the outer edges of the solar system where such comets are formed and then get occasionally deflected towards the inner solar system.

Halley's Comet is a short-period comet that orbits the Sun roughly every 76 years. It is named after astronomer Edmond Halley, who calculated its orbit and predicted its return. The comet is known for its bright appearance when it comes close to Earth, with its most recent sighting in 1986.

The space probe designed for sampling comet dust is known as NASA's Stardust spacecraft. It was launched in 1999 with the primary mission of collecting comet material from comet Wild 2 and returning it to Earth in 2006.

Halley Stubis is a motion graphics artist, mainly known for her work on Call of Duty: Modern Warfare and Advanced Warfare. She has also worked on various other video game projects, as well as commercials and film projects.

Comets do not have days or years like planets or moons. Instead, they follow highly elliptical paths around the Sun, with varying speeds depending on their distance from the Sun. Their orbits can range from several years to thousands of years to complete one revolution around the Sun.

Both comets and Earth are celestial bodies located in our solar system. Comets are composed of ice, dust, and rocky material, similar to the materials present on Earth. Additionally, both comets and Earth experience gravitational forces from the sun that affect their orbits and movements.

Comet West was discovered on August 10, 1975 by Richard M. West using a 15-cm Schmidt telescope at the European Southern Observatory in Chile. It was the brightest comet in the sky for several weeks, reaching a peak brightness around March 1976.

A space object formed from dust and rock particles mixed with frozen water, methane, and ammonia that forms a bright coma as it approaches the sun is a comet.

We're not even certain that OUR star has an Oort cloud. The hypothetical Oort Cloud is too far away, and is composed of bodies generally too small, for us to be able to detect anything there even with our most sensitive telescopes.

However, this is one of those things that we cannot yet prove, but which sounds reasonable; that there is probably some left-over material around the solar system that never quite fell close enough to the planetary nebula to be included in the formation of the various planets. That some of this material, influenced by some gravitational force over eons, continues to fall in toward the Sun and the inner regions of our solar system.

So, while we have to say, "We don't know for sure", the answer is "Probably, yes."

Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.

A comet travels in a long cigar-shaped path around the sun. Comets are icy bodies that release gas and dust as they approach the sun, creating a glowing coma and tail. These objects have highly elliptical orbits that can take them far out into the solar system before swinging back close to the sun.

Halley's Comet was last seen in 1986 and won't be visible again until 2061.

From Wikipedia: "Halley's Comet ... is visible from Earth every 75 to 76 years. ... Halley's Comet last appeared in the inner Solar System in 1986 and will next appear in mid-2061."

You will be able to see other comets, though.

It accelerates towards the star. This is due to the increased force of gravity which is inversely proportional to the square of distance between the masses; as they get closer, gravity pulls harder. An increased force means a greater acceleration due to gravity.

While we are certain that a large comet or asteroid certainly WILL hit the Earth, we have no good candidates in mind. It will probably take us by surprise.

A few years ago, astronomers identified a large asteroid that appeared to be headed right for us! It was going to hit the Earth in 2029! On Friday the 13th!

Ooops! Never mind...... Tuned out that with more accurate observations of the asteroid's orbit, it probably won't hit at all. Might not even come close enough to see.

But scientists are coming to recognize that while a major asteroid strike is a VERY unlikely event, if it DOES happen, it would ruin everybody's day. So astronomers have started watching for Near Earth Objects, and hope to identify and catalog every asteroid bigger than a basketball to make sure that it does NOT hit earth.

At least, not any time soon.

One comet myth is the belief that comets were seen as omens of great events, such as wars or natural disasters, in various ancient cultures.

simple and easy a comet a comet has a solid center nucleus that contains rock particles trapped in frozen liqud

this forms the tail: as it moves closer to the sun the "outer ice" turns to gas and the solid particles (pieces) turn to dust

The stage that comes first in the life cycle of a high-mass star is the main sequence stage. During this stage, the star fuses hydrogen into helium in its core, maintaining a balance between radiation pressure and gravity.

Locating a moon colony near ice deposits from impacting comets would provide a nearby water source that could be used for drinking, growing food, and producing oxygen for life support. It would reduce the need to transport water from Earth or extract it from other sources on the moon.

Scientists use telescopes, including ground-based and space-based ones like Hubble, to study asteroids and comets. Spacecraft missions, such as NASA's OSIRIS-REx and ESA's Rosetta, are also used to perform close-up studies and sample collection from these celestial bodies. Spectroscopy, radar imaging, and infrared observations are common techniques used to analyze their composition and characteristics.

Technically, once a meteor reachest the surface, it is no longer a mateor but a meteorite. In very large impacts, the impacting object can be vaporized by the heat generate. Smaller objects may be shattered by the force of impact or buried as the side of the crater collapse. Additionaly, to the untrained eye, a meteorite can be hard to distinguish from an ordinary rock.

Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact.

Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.
