- Comets have been classified into two distinct categories: Short-period comets – which are called ecliptic comets. Long-period comets – which are called nearly isotropic comets. One AU is the distance between Earth and the Sun. Short-period comets have relatively small orbits, usually below 10 AU.

Comets are celestial objects made out of frozen gases, rock and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet’s orbit brings it near the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets while the tail stretches away from the Sun for millions of miles.

Comets are mostly found way out in the solar system. Some exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt. We call these short-period comets. They take less than 200 years to orbit the Sun. Other comets live in the Oort Cloud, the sphere-shaped, outer edge of the solar system that is about 50 times farther away from the Sun ...
The gravity of a planet or star can pull comets from their homes in the Kuiper Belt or Oort Cloud. This tug can redirect a comet toward the Sun. The paths of these redirected comets look like long, stretched ovals. As the comet is pulled faster and faster toward the Sun, it swings around behind the Sun, then heads back toward where it came from. So...
At the heart of every comet is a solid, frozen core called the nucleus. This ball of dust and ice is usually less than 10 miles (16 kilometers) across – about the size of a small town. When comets are out in the Kuiper Belt or Oort Cloud, scientists believe that’s pretty much all there is to them – just frozen nuclei. But when a comet gets close to...
As dust and gases stream away from the nucleus, sunlight and particles coming from the Sun push them into a bright tail that stretches behind the comet for millions of miles. When astronomers look closely, they find that comets actually have two separate tails. One looks white and is made of dust. This dust tail traces a broad, gently curving path ...
People have been interested in comets for thousands of years. But it wasn't possible to get a good view of a comet nucleus from Earth since it is shrouded by the gas and dust of the coma. In recent years, though, several spacecraft have had the chance to study comets up close. NASA’s Stardust mission collected samples from Comet Wild 2 (prounounced...
As a comet nears the sun, ice and dust boil from its slushy center—called a nucleus—to form an atmosphere known as a coma. Sunlight “blows” gas and dust from this coma to create a spectacular tail. Some tails reach 100 million miles (160 million kilometers) long and can be seen from Earth, the comfiest seat in the solar system for comet ...

Introduction. A comet is a small chunk of dust and ice that orbits, or travels around, the sun. It is sometimes described as a “dirty snowball.” There are billions of comets in the solar system, but most never pass close by Earth. The best-known comet is called Halley’s Comet. It can be seen from Earth about every 76 years. Orbit.
Jun 15, 2023 · What is a comet? (explained for kids) A comet is just a big ball of ice and rock that travels through space. You can think of them as giant snowballs that are the size of an island. When comets get closer to the Sun, the ice begins to melt, and tiny pieces of dust and gas are released.

The typical comet has a core that is a few kilometers in diameter. Comets are often called the "dirty snowballs" of the Solar System. Coma and Tail.
