The researchers suggested that another sun was born in the giant Oort cloud, from which the solar system was formed later, and we are talking about a double star system. The companion was located at a considerable distance from the main luminary, at the same time it can be considered a twin brother. It is located from the Earth at a distance of 1,000 times farther than the main star and looks in the sky like a bright object in the constellation Peacock.
The proof of the relationship is the coincidence of the chemical composition, reminiscent of the sun. At the same time, the mass of the twin exceeds the main star by 15%. The second star formed 4.6 billion years ago from dust and gas entering the Oort cloud.
