Nasa has found a distant star circled by eight planets, equal to the complement in our own Solar System. It's the largest number of worlds ever discovered in a planetary system outside our own.
The star known as Kepler-90, is just a bit hotter and larger than the Sun; astronomers already knew of seven planets around it. The newly discovered world is small enough to be rocky, according to scientists.

Engineers from Google used a type of artificial intelligence called machine learning to find planets that were missed by previous searches. The discovery was based on observations gathered by Nasa's Kepler Space Telescope.
Its parent star is very distant, lying 2,545 light-years away. But its planetary system appears to be ordered in a similar way to our own.
Andrew Vanderburg, a co-discoverer at the University of Texas at Austin, said: "The Kepler-90 star system is like a mini version of our Solar System. You have small planets inside and big planets outside, but everything is scrunched in much closer." To give a sense of how close, the outermost planet in the system orbits at around the same distance the Earth does from the Sun.
