Exoplanet tally set to pass 4,000 mark
The number of planets detected around other stars - or exoplanets - is set to hit the 4,000 mark.
The huge haul is a sign of the explosion of findings from searches with telescopes on the ground and in space over the last 25 years.
It's also an indication of just how common planets are - with most stars in the Milky Way hosting at least one world in orbit around them.
That's something astronomers couldn't be certain of just 30 years ago.
, run by the Observatoire de Paris, has already passed the 4,000 mark.
Dr Françoise Roques, from the observatory, who is on the scientific board of the encyclopedia, told BBC News: "The great news is that we shift from a starry sky to a planetary sky, as there are more planets than stars.
"And also that the planetary systems have great diversity of structure, with planets orbiting zero, one, two... stars, or other planets."
is 74 planets away from the milestone. But there are 443 planet candidates detected by Nasa's Tess space telescope (launched in 2018) awaiting confirmation.
There are a further 2,423 candidates detected by the Kepler space telescope.
The latest exoplanet to be added to the Nasa archive was the Super Earth GI 686 b, which orbits a red dwarf star (a type cooler than our Sun) which was discovered using ground telescopes. It was added on 21 March.
