The TSS satellite in NASA discovered this planet, which was called “GJ 12 B” or (Gliese 12 b), and was studied in detail using the “Maroon-X” tool, installed on the international observatory (Gemini), allowing to measure the mass, density and transaction of orbit or orbit of small external planets, especially in systems indicated in the systems.
It turns out that the size of the planet “GJ 12 B” is approximately the size of the Earth, since its radius is equivalent to 0.96 of the radius of the Earth, and its surface temperature is about 27 ° C. Its mass is approximately 0.71 ground mass. Scientists believe that its density is comparable to the density of the earth or slightly less, which may indicate the presence of air cover or volatile compounds, such as water, or a lower percentage of heavy elements in its composition.
Scientists believe that the star of the planet “GJ 12 B” is of particular importance. This is a static and inactive dwarf, which means that the conditions for its monitoring of the atmosphere using James’s web Telescope are more convenient. For comparison, in the Trappist-1 system, which also contains many external planets the size of the Earth, but the activity of the star around the planets holds these studies due to strong magnetic candles and “noise”.
According to astronomers, although the orbit of the planet “GJ 12 b” is more elongated than the orbit of the Earth (tropical deviation 0.16 versus 0.017), it is located on the inner edge of the region suitable for its star. That is, on its surface there may be conditions for liquid water- one of the main signs of the possibility of life.
