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.

9 != 8

Pluto forever!

More seriously, we're probably not within a century of being able to detect Pluto-mass KBOs around other stars, so it doesn't count in this context whether we count it as a planet locally or not.

Some 3,500 exoplanets - worlds circling other stars - have been documented in recent decades.

Amazing. guessed it was only in the hundreds.
