The Sun is the central star of the solar system. And all the planets, asteroids, comets, dust and satellites rotate around them. It has a mass 332.900 times greater than that of Earth, and a volume 1.300.000 times greater. Already in the first years of school we learned about the magnitude of this star. But have you ever heard of the star Nemesis?

Nemesis, the sister of the sun.

The hypothetical companion of the sun was first suggested in 1985 by physicists R.A. Muller, Piet Hut and Marc Davis. The hypothesis was raised that the sun would have a “twin sister” that would be a small, dark star, known as a brown dwarf, with an orbit thousands of times farther away than Pluto.
In this theory, the sun would be part of a binary system. Its sister star is called Nemesis or “Death Star” because of its high potential for destruction. It could fling comets, meteors and asteroids against the Earth and the interior of the solar system. The theory says that its orbit around the sun lasts for about 27 million years. At one point it crosses the Oort cloud and flings asteroids and comets on all sides, reaching our solar system and reaching the earth.
There are no studies to prove their existence. The absence of an unambiguous gravitational field or striking craters has made the possibility of the existence of the sister of the Sun remain only in theory.

Sedna

The discovery of this dwarf planet raised again the theory of the star Nemesis. According to Mike Brown, the discoverer of Sedna, the planet should not be there. It never comes close enough to be affected by the sun and never goes far enough to be affected by other stars.
Another suspect for the existence of Nemesis is that comets and asteroids within the solar system appear to come from much of the same region of the Oort cloud. It’s believed that the gravitational influence of a massive solar companion would break the balance of a part of the cloud, mirroring comets, meteors and asteroids in its wake.

Oort Cloud

The Oort cloud, also called Öpik-Oort, is a hypothetical spherical cloud located at the edge of the Solar System, consisting of numerous celestial objects such as comets and asteroids. Although not yet directly observed, there are good indications for its existence.

Telescope Wise

The Wise Telescope may be the hope to find the sister star of the Sun. It was released in December 2009 with the goal of mapping the sky in the infrared spectrum. He has made countless important discoveries and detected dozens of new comets, but with the gigantic amount of data generated to be panned, the possible discovery of Nemesis could take years.

For now, this is the information about the twin sister star of the sun, and do you believe in the existence of Nemesis? Tell us there in the comments. 😊
