For a long time, humanity has tried to find the planet most similar to Earth around The cosmos. But he was always running into unanswered questions. Even so, our search is not over and it seems that it is currently paying off.
This extrasolar planet was discovered by scientists in old reviews of data collected by the Kepler space telescope. It is considered the most Earth-like planet due to its size and temperature. It is located 300 light years from our solar system and orbits a star. For these reasons it is said that it could have water on its surface and, most likely, life.
Until this moment it was overlooked in research by what is now a study center for astronomers. According to calculations, it is only 1.06 times greater than Earth and receives 75% of the light that we receive from the Sun. These data indicate that the planet’s temperature may be habitable, if it is not already habitable.
This is not all good news about Kepler-1649c, there is also bad news. The point is that it orbits a red dwarf. These types of stars are well known for the large explosions and bursts they produce, so life there may be a challenge.
Do we know everything?
There are still many things that are unknown about the considered planet most similar to Earth (Kepler-1649c). The first one is of great importance, its atmosphere. This element could be essential because it would affect the temperature on the planet.
Despite all the resources and time devoted to studying the planet Kepler-1649c, it is subject to errors. It is due to the errors in the measurements of such distant planets. Despite these, any type of planets orbiting a red dwarf is of great astrobiological interest, as they could be promising for life as it surrounds us.
Is it just this planet?
Well, no! According to observations, it is calculated that there are other planets of similar sizes to Earth that compete for the position of being the planet most similar to Earth. Among them are:
– Teegarden c
– TOI 700d
The first two are quite similar in size to our planet. The next two are closer to our environment because of their temperature. These findings are the most relevant of those found in the solar system. To know the situation of extreme temperatures on earth click here
According to the University of Texas scholar, they would have missed the opportunity to study the planet most similar to Earth (Kepler-1649c) but they would have reviewed the mislabeled planets under a rigorous algorithm that requires a lot of work at hand.
Your solar system
Kepler-1649c’s orbit is so close to its little red dwarf that its year equates to just 19.5 Earth days. In subsequent observations, a rocky planet more or less similar to the size of Kepler-1649c but its orbit is half traveled. The most analogous thing in our solar system is the trajectory of Venus.
Red dwarfs are the most frequent stars in the solar system, so astros, such as the “planet most similar to Earth”, can be common in the universe.
Scientists are intrigued not only by this planet, but by the overall structure of its system. Each time the outermost planet in this solar system makes its way around its star, Kepler-1649c goes only 4 times. The relationship remains stable, so it is synonymous with great stability and it is forecast that this will be the case for a good time.
This type of proportions is very rare in the universe. The most common is to find symmetries from 3 to 2. This phenomenon is called orbital resonance. For all these reasons, Kepler-1649c is thought to be the planet most similar to Earth.
Another of the planets found, in this case by the United States Space Agency, NASA, which closely resembles terrestrial conditions. It is a planet 60% larger than Earth. It rotates its star at almost the same distance that the Earth does around the Sun.
It is located 1,400 light-years from the Milky Way, in the constellation Cygnus. It takes Kepler-452b 385 days to orbit its star, only 5% faster than Earth. Its star is only 4 percent bigger than our Sun and 10% brighter.
TOI 700 d
This exoplanet discovered by NASA’s Jet Propulsion Laboratory and its TESS satellite is also on the list of planets with conditions similar to Earth and potentially habitable. It is 100 light years away and its distance from its star is intermediate. The presence of water is totally probable due to its setting.
It was initially misclassified as a larger and hot planet, but several amateur astronomers were able to identify the error. A graduate student at the University of Chicago named Emily Gilbert, was primarily responsible for the discovery. He corrected the parameters of the star and thus the sizes of its planets were reduced. Thus it was possible to realize that the TOI 700 d was within the habitable zone due to its size. Another great discovery is that of the tear-shaped stars, to find out more click here
His data is: 20% larger than Earth, orbits its star in 37 days and receives 86% of the energy that Earth receives from the Sun. Its star is 40% the size of the Sun and 50% less hot. Due to these circumstances, NASA affirms that the possibility that the planet is covered with oceans is not far from the truth. It is also based on the discovery that the atmosphere around it is dense in carbon dioxide.
One of its faces is always towards its star, just like the Earth and the Moon. This phenomenon is known as asynchronous rotation. Simulations made from the data collected predict that the winds occur from the far side of the planet towards the one that is illuminated.
Definitely the universe is a subject to study and that raises many questions as new discoveries are discovered, the discoveries made by the Kepler telescope will give us a world of possibilities, as well as the other findings made with projects carried out with the Hubble Telescope and other telescopes that are at the forefront of new projects carried out in deep space.
