Comets.
Look up into the sky. Stars, planets, comets, asteroids, galaxies, etc., are celestial bodies.
Asteroids and comets are alike in that they are both heavenly or celestial bodies. Most of them were born early in the formation of the solar system too.
Other celestial bodies in space include comets, asteroids, moons, and stars. Comets are icy objects that release gas and dust as they approach the sun. Asteroids are rocky objects that orbit the sun. Moons are natural satellites that orbit planets. Stars are massive balls of gas that emit light and heat energy.
A celestial body is any physical body beyond the earth's atmosphere.
Astronomy is the study of the universe (celestial objects such as stars, planets, comets, nebulae, star cluster, and galaxies).
"Comets: The "Special Guest Stars" in the Celestial drama".
Comets can be captured by planets, ejected from the solar system, or collide with a celestial body such as a planet or star. Some comets may break apart or disintegrate due to the effects of gravitational forces and their volatile nature.
Comets originate from the Oort cloud, a spherical shell of icy bodies at the outer edges of our solar system. These comets can be perturbed and sent into the inner solar system where they become visible as they approach 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.
Astronomical objects moving through space are typically referred to as celestial bodies or celestial objects. They can include planets, asteroids, comets, and moons.
I am pretty sure that comets are lighter than moons but it depends on the comet
