What are all the different types of rock bodies that can be found in Space?
Example: Meteors, Asteriods, Comets, planetiods.
I will thumbs up all answers.
You don't have to mention all the rock bodies that exist, just as much as you can.

Asteroids
Large rocky airless objects that resemble huge boulders, they range in size from a few meters to many tens or even hundreds of kilometres in diameter. The largest asteroid in the Solar System is Ceres with a diameter of 952km.

Asteroids are usually found in the Asteroid belt between Mars and Jupiter, and the Kuiper belt beyond the most distant planet, Neptune. But there are many that drift through space orbiting the Sun. Some of these rogue asteroids pose the biggest danger to Earth as some pass quite close.

Comets
Large objects made up of rock, dust and ice, tens of kilometres in size that originate from the Oort cloud at the extremes of the solar system, they are remnants of its creation billions of years ago. Comets are often referred to as dirty snowballs that have been knocked out of the Oort cloud by a collision, or the gravity of a passing star sends them hurtling toward the Sun.

Meteoroids
A small particle of rock or dust left behind by an asteroid or comet and is significantly smaller in size, ranging from a grain of sand to roughly a meter wide.

Meteors
The visible streak of light caused by an object such as a meteoroid, asteroid or other space debris as it enters Earth’s atmosphere. Heat causes the object to glow as it heats up and the streak of light is also known as a shooting star.

Meteorites
A meteor that has impacted the ground, an object can only be classed as a meteorite after impact and can be identified by varying techniques including; testing the object to see if it is magnetic at the impact site or looking for elements such as iridium in a lab.

Recently, James found an oddly-colored rock in his backyard and surmised that it came from space. James sent the rock off for elemental analysis to confirm his theory. Isotopic analysis via mass spectrometry found appreciable amounts of (26)^Al and (26)^Mg in the sample (275 μg and 81.3 μg, respectively). These isotopes are formed only when cosmic species are bombarded with solar rays to form 26Al, which then radioactively decays into 26Mg, with t1/2 = 7.17 × 105 years. Given the...
