do asteroids have an atmosphere?
157355
Asteroids have no atmosphere, but many are large enough to exert a gravitational pull — some, in fact, have one or two companion moons, or they form binary systems, in which two similarly sized asteroids orbit each other.

Mars' atmosphere however is 95% carbon dioxide, 3% nitrogen, 1.6% argon, and it has traces of oxygen, carbon monoxide, water, methane, and other gases, along with a lot of dust. Dust hanging in the air colors Martian skies tan in photos taken from the surface. Relative to Earth, the air on Mars is extremely thin.

The Short Answer: An asteroid is a small rocky object that orbits the Sun. Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. ... A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth's atmosphere.

Dwarf planets orbit the Sun, and unlike smaller objects such as asteroids, they also have enough mass to form a sphere; however they don't have the gravity needed to clear their orbits of other objects and debris.

Comets are similar to asteroids, but are made of ice, dust and rocky material. As a comet approaches the Sun, it begins to vaporise, which means that it turns into a gas. It then produces a distinctive tail. The main difference between asteroids and comets is their composition, as in, what they are made of.

The atmosphere of a comet, called its "coma," is made of gas and dust that spew out of the sun-warmed nucleus. The atmosphere of a typical comet is wider than Jupiter.

Comet: A body of ice, rock and dust that can be several miles in diameter and orbits the sun. Debris from comets is the source of many meteoroids. ... Meteor: A meteoroid that enters the earth's atmosphere and vaporizes. Also called a “shooting star.”

Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt—a region between the orbits of Mars and Jupiter.

Pluto has a thin, tenuous atmosphere that expands when it comes closer to the sun and collapses as it moves farther away—similar to a comet. The main constituent is molecular nitrogen, though molecules of methane and carbon monoxide have also been detected.

The atmospheric characteristics of rocky and gas planets differ. ... The terrestrial planets in the solar system have atmospheres made up mostly of gases such as carbon dioxide, nitrogen and oxygen. The gas giants, on the other hand, consist mainly of lighter gases like hydrogen and helium.
132257
The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases, and all terrestrial planets have rocky surfaces. ... Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets.

An asteroid is a small rocky object that orbits the Sun. ... A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth's atmosphere, creating a streak of light in the sky. An asteroid is a small rocky object that orbits the Sun.

Space is the vacuum that exists between celestial bodies. The simplest explanation is that it's just an empty area . Atmosphere on the other hand is the sum of gases that suround a celestial body. Our atmosphere for example is composed of nitrogen oxygen argon and carbon dioxide.

There are 8 planets and over 160 moons in the solar system. Of these, the planets Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have significant atmospheres. Pluto (a dwarf planet) may have an appreciable atmosphere, but perhaps only when its highly elliptical orbit is closest to the Sun.

Asteroids certainly hit the sun after having their orbits disturbed by the planets - most objects with unstable orbits only have a few possible destinations in the solar system (the Sun or the planets).

Although asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt—a region between the orbits of Mars and Jupiter. Some asteroids go in front of and behind Jupiter.

But some objects blur the distinction between asteroids and comets. Asteroids are generally considered to be made up of metals and rocky material, while comets are made up of ice, dust and rocky material. ... Asteroids formed much closer to the sun, where it was too warm for ices to remain solid.
