Planetary System With More Planets Than Our Own Is Discovered

Planetary System Bigger Than Our Own

While the search for extraterrestrial life has yet to produce any results, scientists examining planetary systems have found multiple new planets surrounding the star HD 10180, leading to speculation that the planetary system surrounding the star has more planets than our own system.

The discover was made by an astronomer at the University of Hertfordshire and if correct it will be the only solar system so far that has been revealed to have more planets than our own solar system.

In order to determine the number of planets in the system scientists used complex mathematical equations to determine the gravitational pulls on the star HD 10180. Researchers took their measurements using the High Accuracy Radial Velocity Planet Searchers (HARPS) telescope.

According to PopSci:

The first batch of HD 10190’s planets were discovered in 2010 and¬†Neptune-sized, or about 13 to 25 times the size of Earth. The other, more recently discovered planets are closer in mass to our planet, though much closer to their sun distance-wise than Earth. The planets follow a regular motion around their sun similar to our own star system, with periods between 1.2 and 600 days.

The system has nine planets, one more than our own solar system although researchers point out that none of the planets are capable of sustaining life in fact the planets are so hot that they likely couldn’t sustain any type of metals and even if they were inhabitable it would take forever to get there, HD 10180 is 127 light-years away from Earth.
