Located 100 light-years from Earth, the planet has all the conditions to make new places for mankind

In April 2018, the US space and space agency NASA launched the Tess space telescope, which was specially designed to detect and track planets outside the Solar System. The priority of this telescope is to look for planets similar in size to Earth and send their outer images to scientists for analysis.

Most recently, at the annual meeting of the American Astronomical Society, a representative of NASA announced the discovery of a planet with many features most similar to the Earth, named TOI 700 d.

According to NASA, the planet was actually discovered at the beginning of this year. However, due to some errors in the process of parameter analysis, the TOI 700 d was misclassified by scientists when they thought the planet was larger and had a surface temperature hotter than it actually was. However, after a more detailed observation, the researchers realized the life potential of TOI 700 d.

The TESS telescope has a mission to search for exoplanets with potential for life.

When we correction repair again parameter of the stars, dimensions of planets as well reduced. So, we is already TOI discovered 700 d as well sized almost the same as Earth and listed in the area habitable. Next, we use the Spitzer space telescope to confirm the accuracy and produce the official results.“- A NASA researcher said.

It is known that the Tess telescope has detected a total of 4 planets the size of Earth. They are named TOI 700a, b, c, d, orbiting the star TOI 700, 100 light years from Earth. Of these, the TOI 700d alone is in the “Goldilocks Region,” which has a moderate distance from the host star – neither too far nor too close, where temperatures can allow the existence of liquid water.

According to NASA, the star star TOI 700 is quite small, only 40% the size of the Sun, while the surface temperature is only half. Meanwhile, the planet TOI 700d is about 20% larger than Earth and orbits the star TOI 700 in a 37-day period. It receives 86% of the energy the Earth receives from the Sun. The difference is that one side of the planet always has daylight.

Computer simulations show that the 700-pound TOI planet can be covered in oceans with a dense atmosphere and filled with CO2. After this announcement, many astronomers will focus on observing the TOI 700 d with other devices to get the most complete data possible.

This is a very interesting discovery for astronomers because the TOI 700 d is one of the few planets that can have life outside the Solar System and is about the size of Earth.
