They're distant cousins.
it was born from the interstellar cloud
Condensed clouds of interstellar gas that originally assembled from the remnants of nova or supernova stellar explosions that occurred many eons before our Solar System was formed.
enormous dark clouds of interstellar dust entered the solar system blocking the light from the sun. making the earth cold.
The solar system was previously a cloud of interstellar gas.
Not yet - but in about 5 billion years - yes.
A collapsing interstellar sloud
FALSE. The outer edge of the "Oort Cloud" of comets marks the end of the Solar System.
It could be called interstellar space or terrestrial.
The Solar System has no predefined limits.Generally the limit of the Solar System and interstellar space is at a place called the Roche limit where our own Sun's gravitational influence is diminished by another - usually star - interstellar object.This boundary is generally accepted to be the mean distance between our Sun and Alpha Centauri A or about 2 light years from the Sun.
the rest of the universe and other solar systems
The only moon in our solar system with clouds is Titan, Saturn's largest moon. It is the only moon in our solar system with a dense atmosphere.
The heliopause marks the outer boundary of our solar system. This is where the solar wind from the Sun meets the interstellar medium of space.
