These two planets at 500 light-years would be very similar to Earth

Kepler 186-f and Kepler 62-f would be in what is called the "habitable zone" of their own solar system and are apparently very similar to the Earth.

The Earth is a planet in which many coincidences They allowed the existence of life. We are in the habitable zone of the solar system, in which neither cold nor excessive heat is tolerated . In addition, it has an adequate atmosphere, a defensive magnetic field and climatic stability due to its inclination to the sun . This, not to mention the presence of liquid water.

Since we can observe the space is unknown if there are more planets similar to ours. The mere possibility of living elsewhere in the universe raises many questions for our heads . However, we already have some good candidates similar to our beloved home .

We are talking about Kepler-62f and Kepler-186f . A study by the Georgia Institute of Technology revealed that these planets looked like the Earth. While the first is located about 500 light-years away from us, the second is at a distance of 1200 light-years

These astronomical objects would have more coincidences than we think. Not only do they conform to the basic notions of habitability, but apparently they could also have stable seasonal periods . This is due to its axial inclination .

<h3> The relevance of axial tilt </h3>
<p><strong>  The axial tilt is nothing more than the angle that a planet has on its own axis compared to the sun </strong>. In general, this varies between its own poles in certain periods of time. On Earth, it generates the four seasons we all know. When it is summer, we are in the area closest to the sun; while in the winter we are in the farthest. </p>
<p>  <strong> Although we believe that temperatures between summer and winter vary widely, these changes do not prove to be very harmful to the existence of life </strong>. After all, the maximum that the Earth is inclined is 22.1 degrees. Compared to extreme cases such as Uranus (97.7 degrees) this is quite normal. </p>
<p>  <strong> The researchers believe that the Kepler-186f axial tilt is constant </strong>. In this way, it is very possible that it also has regular seasons and a very stable climate. The same thing would apply to Kepler-62f, which is considered a "Super Earth" because of its large size. </p>
<p>  <strong> The importance of this is that it can facilitate the existence of life on these planets, if it is not there already </strong> ]. In fact, one of the authors of the study, Gongjie Li, recounted the current state of Mars with its degree of inclination: </p>
<blockquote>
<p>  "Mars is in the habitable zone of our solar system, but its axial inclination was very unstable, ranging from zero to 60 degrees <strong>. This instability probably contributed to the decomposition of the Martian atmosphere and the evaporation of water from its surface. </strong>. "</p>
</blockquote>
<p><strong>  On the other hand, the presence of neighboring planets can influence the stability of this inclination </strong>. Fortunately for the Earth, Mars does not affect it at all thanks to the Moon. It is not known at present whether Kepler-186f and Kepler-62f have satellites, but do not appear to be affected by neighboring organisms. </p>
<p>  <strong> Kepler-186f has less than 10% of radius than Earth, but its mbad and density remains a mystery </strong>. Complete an orbit around your star every 130 days. According to NASA, the brightness of this star at noon looks as bright as the sun just before sunset here on Earth. Kepler-186f is in the constellation Cygnus as part of a star system of five planets </p>
<p>  <strong> We will have to wait in the future if science discovers more similarities between these planets and ours </strong> . Who knows, maybe there is life on their surface. </p>
