Jupiter Could Have Become the Second Star in our Solar System

About half of all the star systems in our galaxy are made of couples or triplets of stars. Our Solar System, on the other hand, only has one star, the Sun, and a few small planets. However, this was almost not the case, as Jupiter was on the verge of becoming a star along with the Sun.

Jupiter is the biggest planet in the Solar System, and also the largest. It is so immensely big that it is right on the edge of becoming a star, just like the Sun. If it were approximately 20 times bigger than it is, it would have a sufficient mass for the pressures and temperatures in the nucleus to ignite nuclear fusion and put Jupiter on the path to becoming a star.

An Almost Second Star in Our Solar System

The material the formed our Solar system accumulated to create the planets, and most of that material got on Jupiter through runaway exponential growth. A small bunch of rocks and ice, most likely about five to ten times the mass of our planet, formed a core that suctioned all the surrounding hydrogen and helium as fast as it could.

When talking about exponential growth, 20 times bigger is not that much, but according to researchers, the planet Jupiter would have ended up blowing up and lighting the cosmos as a second sun, if the Solar System was just a little bit different.

However, this doesn’t exclude the possibility of the formation of other planets, such as the planets rotating around binary stars. But this would make life on Earth much more far-fetched, as planets that orbit in binary systems almost never get to that optimal place for the action of temperatures required in order to prevent water from either vaporizing because of the heat or freezing from cold.
