Kepler 186f: A Planet in the Habitable Zone?

It’s time to go off on our travels again, and this time we’re going to pay a visit to a star system which has not just one but multiple planets, and one of them happens to lie in the habitable zone of the star. We’re going to Kepler 186, let’s find out more.

Located about 582 light years away we find our star of interest. If you want to see it from earth, you’d have to point yourself at the constellation of Cygnus and have a pretty powerful telescope. Let’s go there now, in our space and time machine it’s just a short hop.

Let us turn our attention firstly to the star, Kepler 186. This is an M class red dwarf star, although it is a large red dwarf on the border between a red and orange star. This star is half the diameter of our sun with about half its mass as well. This means that it has about 5% the luminosity of our sun.

No intros, no monologues just straight to the subject, just the way i like it! Subscribed!

Kepler-186f, along with the other four planets in the system, were discovered in 2014.

Thanks for another great video. Love the mix of subjects. Great way to spend 10 minutes or so

[PizzaPowerXYZ]

Learning more and more every time a video comes out on this channel

[amandaunknown]

always glad to see such a quality video, nice creative blendr art too!

[imeldadariodiaz]

I like how you have a travel capsule for these cool awesome videos

[nyxshorts]

i love your content, please never stop uploading, you teach us alot!

[DDLyon]

Thanks for helping me with my science project

Sir, been watching your videos lately (after recently discovering purely by accident/coincidence); it's a true crime your videos being so informative, good and tecnical but under-viewed.
Kuddos!

Very interesting I'm very intruig to know more

[barmetler]

I don't think it's a problem that that planet is towards the outside of the inhabitable zone, we definitely don't have any issues making a planet warmer XD

[thebeautyofuniverse]

Note here
Realistically, f is in outer edge and close to the edge of outermost habitable zone
F has an estimated equilibrium temperature (or the temperature without anything changing the temperatures like the atmosphere greenhouse effect or the reflectivity) is somewhere -80
So Kepler-186f might need a lot of greenhouse gas way more than earth in order to warm up to temperatures suitable for life, but that amount of greenhouse gas might evaporate more like water or CO2 or any volatiles that is stored, leading to a venus-like atmosphere making it inhospitable
So these scenarios of the planet being dry cold Antarctica-like and planet being venus like, makes the planet very delicate, so it’s more possible the planet might not be hospitable for life
Perhaps the planet might become hospitable to life if it was dry cold Antarctica like when the star ages and becomes brighter and warms kepler-186f to a hospitable temperature’s

I truly believe no human knows what's out there, just a hypothesis, there are other earth like planets but the inhabitants of this world are just guessing the whereabouts and anything else.

[ianbrewer]

itll take 70, 000 years for voyager 1 to reach the alpha centauri system. With our knowledge on technology and what’s physically possible we will probably never be able to leave this solar system

[MrLince-hrof]

are new elements out in the universe we don´t know ?

[sammybivas]

And the punch line is, why do you think that it’s not occupied?

[alvinalex]

It is same anime type: Astra lost in space

[ANTIMANNER_GAMING]

If there were trees on that planet it would be red colored leaves.

Hey, I'm not sure if you'll respond to this, but I got a few suggestions.

1. What if Sirius B Collided with Earth?
2. What if a Rocky Planet had the Mass of Jupiter, a Brown Dwarf, or a Star?

[dallenmcdermott]

shit looks like earth, better than kepler-69c for sure.
