Question

Kepler-186f is much closer to its sun than Earth is to its sun. Why is it considered to be in the habitable zone even though it’s so close to a sun?

Answer 1

answer: Its sun is cooler than our sun, so there is a possibility that water can exist in liquid state on this planet.

Explanation: this is the exact answer.

Answer 2

See the explanation below

Step-by-step explanation:

There are many factors that determine the affordability of a planet, than its distance from the sun. It is clear that the solar radiation received by humans cannot be greater or less than certain values recommended by scientists.

However this planet may have a stronger magnetic field that diverts in large quantities the dangerous radiation that can reach Kepler-186f, in the same way the star of this planet may have less intense radiation than our sun.

These factors can be seen in an easier way by investigating the properties of the planet Kepler-186f which must be different from the planet Earth.
