Our Solar System consists of the Sun, our eight planets, several dwarf planets, and many more smaller objects such as asteroids. The Earth is within the habitable zone of the Sun.
Habitable zones, also called Comfort Zones and Life Zones, are considered orbits about stars that possess small, rocky planets or moons where water does not boil or where it doesn’t stay frozen all of the time.
A
habitable zone (HZ) is a region in space that is considered by human astronomers to be favorable for extraterrestrial life; at least, for life as we know it on Earth.
For this reason that life may be possible, HZs are also sometimes called Goldilock Zones—because they aren’t too hot, aren’t too cold, but 'just right' for the existence of life.
With this expanded search for extraterrestrial life—and with serious expectations that we will eventually find life on other planets—shouldn’t we rename these so far hypothetical alien creatures so they have more serious names.
Extraterrestrial life, or life originating outside of Earth, has yet to be identified as to its existence.
Credible evidence has yet to be identified, according to the scientific community—whether that is directed to microbial or intelligent life outside of Earth, or to intelligent life forms (supposedly) seen here on Earth.
Page three continues with the consideration of life elsewhere in the Universe.
