They are not "interstellar", of course.

Asteroids. Most asteroids lie between the orbits of Mars and Jupiter.
The chunks of metal and rock between the planets are known as asteroids. They are small celestial bodies that orbit the Sun. Asteroids can vary in size, ranging from small boulders to objects several hundred kilometers in diameter. They are primarily found in the asteroid belt, a region located between the orbits of Mars and Jupiter, although some asteroids can also be found in other parts of the solar system.
asteroids are small chunks of rock which move in the asteroid belt between Mars and Jupiter while dwarf planets like Pluto have a centrifugal force and orbit the sun.
The asteroid belt (Main Asteroid Belt) between Mars and Jupiter contains many millions of planetesimals, chunks of rock and ice that apparently never coalesced into a planet.
Canned tuna labeled as flakes, comes from skipjack. Canned tuna labeled as chunks, come from bluefin.
it is a very good question. It starts like this meteors shoot out from Jupiter to a place like earth, if they don't hit anything from millions of miles they will stop. then dark matter (the thing that holds our universe) will put them together and make chunks. then those chunks form bigger chunks so on and so on. finally they make a planet. this takes billions of years.
Those are called satellites.
lakes such as 4 of 5 of the great lkaes were formed by large chunks of ice melting forming a large cavity, rivers are formed by flows of water forming rivers by erosion, or by shifts in underground plates moving the continents
