Exo-Twin: Jupiter's Twin rotates around the Sun Twin

Exo-Twin: Jupiter's Twin rotates around the Sun Twin

The so-called HIP 11915 star not only looks like our Sun, but also has an identical mass and fully corresponds to its age. But the most surprising thing is that astronomers discovered a planet in orbit around it, which strikingly resembles Jupiter, and its mass, as in the case of a star, corresponds to the well-known gas giant, which occupies approximately the same position in orbit around the Sun, which is a duplicate around HIP 11915.

This discovery without doubt has some very interesting implications, since it directly influences the studies of planetary formation and the theory of the formation of planets like Earth, in other areas of the galaxy.

It is also known that Jupiter is a kind of gravitational power plant for our solar system. In the old time, it was a very aggressive and turbulent area, but the gravitational weight of Jupiter stabilized the inner solar system, securing the orbits of all celestial bodies, which allowed to create a favorable environment for the further formation of the Earth.

The modern theory of building the solar system also assumes that Jupiter had a really huge role in its formation, being a kind of space “Vacuum cleaner” clearing the system of many lost asteroids and comets. This allowed life on our planet to be firmly established here, as the number of blows was reduced. The idea of ​​how another planet, similar to Jupiter, behaves, has truly amazing consequences for the further search for other celestial bodies with a developed oasis and gives all the necessary insight into how common planetary systems like ours develop.

“The pursuit of exploring Earth 2.0 and the Solar System 2.0 as a whole is one of the most exciting beginnings in the history of astronomy,” said Jorge Meléndez of the National University of São Paulo, Brazil, leader and co-author of an article on this topic in the journal Astronomy and Astrophysics .

“After two decades of hunting for exoplanets like ours, we are finally starting to see such long-awaited gas giants like those present in our solar system,” said Megan Bedellon from the University of Chicago, a researcher and lead author of the article. “This discovery is exciting in all respects, because the understanding that there may be other similar solar systems, which may be similar to ours even more, gives really inexpressible emotions.”

Now, since the promising Solar System 2.0 has been found, HIP 11915 will become the center of subsequent exoplanetary research. But is there really a small, rocky world at least a little resembling our Earth? Time will tell it and it remains only to wait.
