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.
