Comets are icy bodies in space that release gas and dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them dirty snowballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
EVERYTHING is ALWAYS moving. Nothing stands "still"; in fact, there is no such thing as "still". The Earth is spinning; at the equator, you would be moving at 1,200 miles per hour, without noticing it - because the air is ALSO moving that fast. The Earth is moving, too, at about 66,600 miles per hour in its orbit around the Sun. The Sun is moving, too, because the entire galaxy is spinning once every 200 million years or so. The Milky Way galaxy is also moving, although we can't be sure exactly which way or how fast. Comets are orbiting the Sun, speeding up as they get closer to the Sun and slowing down as they move away.
lahar. It is also known as a mudflow or debris flow, and it can be very destructive as it can travel at high speeds and pick up large rocks and debris along its path. Lahars are often triggered by volcanic eruptions or heavy rainfall on volcanic slopes.
A comet's tail is pushed away from the comet by solar wind. if the comet is moving away from the sun, the tail will be pushed ahead of its trajectory.
Rapidly moving comets have more kinetic energy compared to slowly moving ones. Kinetic energy is the energy of motion, and it increases with an object's velocity.
Comets
yes they are stars or moving ones are comets
Ridges of rock debris that form in front of a glacier are called terminal moraines at the point that the glacier stops moving ahead.

Most of them are moving slowly out beyond the orbit of Neptune, in the kuiper belt. Longer term comets are thought to also be as far out as the Oort cloud.
-- meteoroids -- asteroids -- comets -- satellites -- planets (rocky ones)
There is none. Both comets and planets are in free-fall, moving in accordance with their inertia and the gravitational forces between the Sun and the planet or asteroid.
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
Short period comets that originate beyond the orbit of Neptune but are generally moving level with the orbits of the other planets are in the Kuiper Belt. The Kuiper Belt is a region of the outer solar system that contains icy bodies, including comets, that orbit the Sun beyond Neptune.
Meteor showers are caused by Earth passing through the debris left behind by comets or asteroids as they orbit the sun. When these small particles of dust and rock enter Earth's atmosphere, they burn up, creating the streaks of light known as meteors.
