The milky Way is a pretty average size galaxy, which, however, was able to shelter about 100 billion planets. Each of these worlds has its own unique features and characteristics, sometimes dramatically different from those we are accustomed to see on Earth. One of the more unusual worlds can be a rocky planet LTT1445Ab, which revolves directly around the three stars. Despite the fact that the planet is unlikely to adopt any life, learning its features can bring a great contribution to the development of modern astrophysics.
Planet lit by three stars
System LTT1445Ab is a trio of small red stars that are at a distance of about 22.5 years from our Sun. Exoplanet orbiting LTT 14455A, the brightest star in the system, about 1.35 times more Land and 8 times more massive than her, and getting 5 times more solar radiation of its star. The staff of the Harvard-Smithsonian center for astrophysics believe the detected object in transit due to the fact that its short orbital period, equal to 5 full days, fully exoplanet goes in front of its star, allowing observers on Earth to see the barely noticeable reduction in light emitted by a star.

Located in the neighborhood of the Solar system, exoplanet is giving astronomers a unique opportunity to study carefully the composition of its atmosphere. The main issue for researchers is the possibility of the presence of oxygen and water vapor, which can indicate the possible presence of life. However, even if LTT1445Ab somehow survived and oxygen, researchers at Harvard do not expect to find the exoplanet any traces of potential organisms: the extremely high temperatures and high radiation levels make this place totally unfit for the emergence of biological life.
Despite the fact that the planet of the ternary system is not suitable for life, scientists will continue to collect data about the exoplanet to improve the analysis of atmospheres of distant planets using telescopes “Magellan”, “Hubble” and “Spitzer”. In addition, experts hope to understand whether it is possible to fill the gas envelope of the planet, which is extremely close from its star the distance, using fumes emitted by a planet’s crust.

Exoplanet with three stars may be of interest to researchers because in the ternary system are extremely rare three M-dwarf, which is considered one of the coldest and smallest stars in our galaxy. At a time when the planet rotates around its main star, the other two alternately approach and withdraw from each other, as if in a cosmic dance. In a sense, the presence of the planet in the neighborhood of three stars can be a very fascinating phenomenon, even despite the impossibility of the existence of LTT1445Ab any life. In addition, the views of the daytime sky for exoplanet must be truly cosmic!
