Earth-like planet discovered, learn more

In the search for another Earth-like planet far from our solar system, scientists have discovered the strongest candidate to date, one that is exactly the same size and mass as our Earth, but orbits at just the right distance from its star. That which is necessary for the presence of life there.

Scientists from the Harvard Smithsonian Center for Astrophysics in the United States have published three papers in the latest issue of the Astrophysical Journal, in which this discovery is described in detail. (Paper 1, Paper 2, Paper 3)

The planet, named TOI-700d, is located 102 light-years away from Earth and was spotted by the Transiting Exoplanet Survey Satellite (TESS) space mission. After being discovered.
According to the analysis, it is the most Earth-like planet discovered so far outside our solar system; That is, in terms of its mass and size, it is exactly like the earth.

Its main star is named TOI-700a. It is a “dwarf star” that has become very dim following passing through its infancy, while also having a lower temperature than our Sun. (It should be noted that our sun is passing through its youth phase which will last for regarding five billion years.)

This is the reason why the “Habitable Zone” around it is located at a much shorter distance; And “TOI 700D” is orbiting in the same area.

When this planet has so many features together, does it have an atmosphere like our Earth? Is there even water in liquid form? Is there even life there? In their third paper, the experts have expressed the strong possibility of the presence of life on this planet, such as air, water and life.

However, he also admitted that at present we have no space telescope, no space mission that can definitively find out regarding the atmosphere of a planet so far away and whether or not liquid water exists there. can do Also, there is no such plan for the future.

Therefore, it will be necessary to develop a special space mission in the coming years that can provide final and decisive answers to all these questions.
