Scientists discover six-planet system(6 Exoplanets and HD110067 Star)
In the northern constellation of Coma Berenices in our Milky Way galaxy is a star named HD110067, which is about 20% smaller in mass than our Sun.
6 planets revolve around this star. The star HD110067 and its six planets are located about 100 light years away from our Earth.
These six planets revolve around their star with a rhythm. These planets revolve in such a precise pattern that it can be set to a music.
All these planets revolve around their star very fast. The innermost planet takes about 9 days to orbit the star, and the outermost planet takes about 54 days.
When the nearest planet to the star makes three complete revolutions around it, the other one makes exactly two revolutions during the same time.
In our own Solar System, Pluto is in a similar resonance with Neptune (Pluto orbits our Sun twice every three Neptune orbits).
These six planets are between the size of Earth and Neptune. These planets are called Sub-Neptune. These planets are not like our Earth.
These six planets revolve around their star very closely. So close that all of their orbits can fit within the distance between our Sun and its nearest planet, Mercury.
But the star HD110067 is smaller and less bright than our Sun, so its planets are not affected by radiation as much.
This system has been rotating in the same pattern for 1 billion years. The six planets are orbiting the star in a similar manner and appear to have not changed their positions since their formation.
