An international research team has discovered two planets near the Tigarden star, similar to Earth and potentially suitable for the formation and development of life.

The opening is reported on the website of the University of Göttingen. The planets are located near one of the stars closest to us, the distance to which from the Earth is only 12.5 light years.

Star Tigarden is one of the smallest. Its mass and radius is about 10 times less than solar, and the temperature is only about 2700 degrees Celsius.

Despite its proximity to the Earth, it was discovered only in 2003. The research team has been observing her for the past three years. The data obtained indicate the existence of two planets.

“They are the same as the inner planets of our solar system,” says Dr. Matthias Zehmeister from the Institute of Astrophysics at the University of Göttingen, the main author of the study.

According to astronomers, these two bodies may be part of a large system. One of the planets called Teegarden b. Calculations showed that the temperature on its surface can vary from zero to 50 degrees Celsius.

The distance from it to the star is about 40 times less than the distance from the Earth to the Sun. The second planet – Teegarden c, – has a more severe climate. The temperature on its surface can drop to minus 47 degrees Celsius.
