Astronomers have discovered a third planet in the Kepler-47 system, this new planet named as Kepler-47d.
Using data from NASA’s Kepler space telescope, they detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets Kepler-47b and Kepler-47c.
According to a new study, Kepler-47d is about seven times larger than Earth and also the largest of the three planets in the Kepler-47 circumbinary system.
Kepler-47 system
The Kepler-47 system is approximately 3.5 billion-years-old and it is 3,340 light years away in the direction of the constellation Cygnus.
After the discovery of Kepler-47d, now there are three planets in Kepler-47, that are orbiting two suns.
Kepler-47 is binary star system and only known multi-planet circumbinary system.
Circumbinary planets are those that orbit two stars.
