According to a paper in the journal Astronomical Journal, a family of four stars is called 30 Ari. Previously, scientists believed that this planet is surrounded by three stars, but it was recently discovered fourth.

The exoplanet in the star system 30 Ari is a gas giant, surpassing the mass of Jupiter is almost 10 times. One revolution around the main star is 335 days.

By the way, the central star of this system is the star of the satellite, which is located very close to it, but it is not a planet orbiting around this it. Also in this system, there is also a second celebrity couple – about 150 million km from the first.

According to scientists, if a little dream and imagine that if people are on this planet and look at the sky, we saw would be one small “sun” and the two bright stars that would be visible even during the day.

It is worth adding that this is the second star system consisting of four stars. First discovered by amateur astronomers as early as 2013, it was called KIC 4862625.

Now, researchers believe that such planets in the system are the four stars in the universe can occur much more frequently than previously thought.
