First planetary system discovered with more planets than ours
Scientists may not be having much success in the search for
extraterrestrial life but astronomers seem to have no difficulty in
picking up the presence of new planets. Specifically, an astronomer at
the University of Hertfordshire has discovered the presence of multiple
new planets surrounding the star HD 10180 - enough to give it the crown
as the only solar system discovered to date with more planets than ours.
Astronomers calculated the presence of the planets by analysing the
gravitational pulls on the distant star HD 10180 with the High Accuracy
Radial Velocity Planet Searcher (HARPS) telescope.
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 c**ser 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.
In total, researchers have found nine planets, one more than our
Solar System's eight. None of the planets in the 127 light-year away
solar system appears to be capable of sustaining life - most are so
close to the sun that their scorched surfaces can't even sustain solid
