NASA’s TESS telescope has discovered analogues of six planets in our solar system, helping us learn what our solar system was like billions of years ago.

Astronomers have discovered a unique planetary system consisting of six young exoplanets and possibly one additional planet orbiting the young star TOI-1136. The discovery not only helps improve our understanding of the formation and evolution of planets around young stars, but may also provide an analogy for the solar system in its infancy around 4 billion years ago. TOI-1136 is a nearby dwarf star in the Milky Way galaxy, about 270 light-years from Earth. Scientists are fascinated by this planetary system because of its rarity. Few star systems have such a large number of planets. Although roughly comparable in size to our solar system, it also shows diversity and similarity, allowing discoveries about systems with similar compositions. NASA’s TESS telescope has discovered analogues of six planets in our solar system, helping us learn what our solar system was like billions of years ago. The first exploration of this planetary system began in 2019 with NASA’s TESS space telescope. However, to obtain more detailed information, astronomers used a variety of ground-based telescopes to conduct long-term observations to determine the characteristics of the planet’s atmosphere, including its mass and the shape of its orbit. The planets from TOI-1136 b to TOI-1136 g in the TOI-1136 system are classified as sub-Neptunes. The smallest of the six known planets is twice the size of Earth, but other planets discovered in this system are four times the size of Earth, including the ice giant Uranus and Same as Neptune. All the planets in the TOI-1136 system orbit their star so closely that a complete rotation takes less than 88 Earth days. Mercury, the planet closest to the sun, also has an orbital period of 88 days. If you study these planets, you can imagine that they are all closer to their star than Mercury is to the Sun. The exoplanets of the TOI-1136 system are a unique class of exoplanets that are distinct from the exoplanets of our solar system. But as other planetary systems are studied, more and more scientists believe that this class of planets may be the most common in the galaxy, potentially opening new horizons in our understanding of the universe. Masu. But what’s most interesting about TOI-1136 is the age of the planet and its star. At only 700 million years old, it is relatively young by cosmic standards. Compared to the solar system, which is about 4.5 billion years old, this system seems very young. This creates a unique opportunity to study planets shortly after their formation, allowing us to delve deeper into the processes of planetary system formation and evolution, including the requirements for the formation of our own solar system. Young stars like TOI-1136 also require special care due to their hyperactivity. These observations are of particular interest to the astronomical community because of the strong magnetism and intense sunspots and flares associated with young stars. Radiation from young stars greatly influences the formation and evolution of the planets that orbit them. This activity of young stars creates special conditions for the planet and affects the properties of the atmosphere, which changes over time. The young star has always shownexcitability” and is very active, like a child. This makes it difficult to take accurate measurements. However, such measurements make it possible not only to compare planetary changes, but also to study how the atmospheres of these planets evolved at different distances from their stars, which is important in such studies. This is one of the most important aspects,” said the team’s Stephen Cain. Leader and Professor of Planetary Astrophysics.
