Not really, you're thinking of comets,
asteroids are composed of rock, metal, or a combination of both.
Asteroids are solid rocky objects. Gas giants, like Jupiter and Saturn, are mainly composed of gas.
The Universe
Frozen lumps of gas and rock in space are commonly referred to as comets. Comets are composed of ice, dust, gas, and rocky particles, often forming a visible tail as they approach the Sun and begin to vaporize.
Asteroids have more in common with Mars than with Jupiter. This is because both asteroids and Mars are rocky bodies, while Jupiter is a gas giant. Like Mars, asteroids are composed primarily of rock and metal, whereas Jupiter is mostly made up of gas and lacks a solid surface like asteroids and Mars.
the universe is composed of stars, planets, satellites, asteroids, meteoroids, dust, and gas.
Earth is primarily solid, with a thin layer of gas that makes up its atmosphere. The solid parts of Earth include the crust, mantle, and core, which are composed of various types of rock and metal. The gases in Earth's atmosphere, such as oxygen and nitrogen, are not frozen but are in a gaseous state.
A comet is composed of dust, rock particles, and frozen gases. It typically features a nucleus at its core, surrounded by a glowing coma—a cloud of gas and dust. When a comet approaches the Sun, solar radiation causes the gases to sublimate, forming a tail that always points away from the Sun due to solar wind.
That sounds more like a comet. Meteroids are relatively small rocks. They might have traces of ice or other frozen materials that would be gas at our temperature, but mostly they are just rock, because ice in such small quantities would tend to bleed away into space. Asteroids are much larger, and may often have ice and frozen "gases", but only as a relatively small part of their volume. Comets, on the other hand, are generally ice and frozen gases, with some rock mixed in.
Jupiter is primarily composed of gas but may have a solid silicate rock and ice core.
Asteroids and comets are both celestial bodies that orbit the Sun. They are remnants from the formation of the solar system and are composed of rock, metals, and other materials. However, comets are distinguished by their icy composition and tail of gas and dust when they approach the Sun.
No. An asteroid is just a large chunk of rock. Stars are not rock, but balls of burning gas. Asteroids are formed when planets/moons/larger asteroids collide and parts of the object go flying off into space.
Gas. Jupiter is composed predominantly of hydrogen and helium.
