Habitable Zone facts
While investigating facts about Habitable Zone Planets and Habitable Zone Definition, I found out little known, but curios details like:
The earth will become inhospitable to life in 2 - 3 billion years as the sun increases in temperature, pushing the habitable Goldilocks zone to Mars or beyond.
how to calculate habitable zone?
After the conclusion of the First World War, the French government declared a "Zone Rouge" deemed unfit for human habitation.
What is the habitable zone?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what planets are in the habitable zone in our solar system. Here are 19 of the best facts about Habitable Zone Calculator and Habitable Zone Solar System I managed to collect.
what habitable zone means?
-
The Korean Demilitarized Zone is recognized as one of the most well-preserved areas of temperate habitat in the world due to the lack of human habitation of the area.
-
Forty-two thousand acres of French countryside, known as the Red Zone, are still closed to the public and unsafe for human habitation due to high concentrations of unexploded ordnance left over from the First World War.
-
Earth is only *just* inside the habitable zone by 1%. We very nearly too close to the sun to ever have life as we know it.
-
The impact of large asteroids hitting earth had ejected billions of tons of life-bearing rocks and water into space, which might reach habitable zones within our solar system as well as in interstellar space
-
In 2013 astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of stars in just our Milky Way galaxy alone.
-
Galaxies have their own habitable zone, just like stars
-
There could be as many as 40 billion Earth-sized planets orbiting in the habitable zones....
-
An extrasolar planet called Cancri f in the Cancer constellation (around 41 lightyears away) is the only known planet outside our solar system which spends its entire orbit within it's stars habitable zone
-
TRAPPIST-1 has 7 temperate terrestrial planets orbiting the its star, 5 of which are similar in size to Earth and 3 of which orbit within the habitable zone
-
The habitable area around a star, that is not too cold or too hot, is called the Goldilocks zone

For your convenience take a look at Habitable Zone figures with stats and charts presented as graphic.
Why is the habitable zone called the goldilocks zone?
You can easily fact check why can a star have several habitable zones by examining the linked well-known sources.
NASA’s Hubble Found Water Vapor on Habitable-Zone Exoplanet for 1st Time
Our Solar System sits within a 'galactic habitable zone', much like how the Earth sits within the 'Goldilocks zone' of our Solar System; making extraterrestrial life MUCH less likely - source
NASA's Kepler Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star - source
Astronomers found a super-Earth planet in the habitable zone of a Sun-like star, some 1,400 light-years away from us
The current far future timeline of humankind includes an astroengineering project to alter the Earth's orbit by repeated asteroid gravity assists to compensate for the Sun's increasing brightness and outward migration of the habitable zone within a period of a billion years from now. - source
When will mars be in the habitable zone?
Galaxies themselves have a habitable zone, just like stars
How many planets are in the habitable zone?
My opinion on scientist who only look for alien life similar to life on earth (they say the planets position in the habitable zone is a requirement), which I think is stupid and narrowminded, has a name.
